pugixml 1.6

-

- Introduction -

-

- pugixml is a light-weight C++ XML - processing library. It consists of a DOM-like interface with rich traversal/modification - capabilities, an extremely fast XML parser which constructs the DOM tree - from an XML file/buffer, and an XPath 1.0 implementation for complex data-driven - tree queries. Full Unicode support is also available, with Unicode interface - variants and conversions between different Unicode encodings (which happen - automatically during parsing/saving). The library is extremely portable and - easy to integrate and use. pugixml is developed and maintained since 2006 - and has many users. All code is distributed under the MIT - license, making it completely free to use in both open-source and - proprietary applications. -

-

- pugixml enables very fast, convenient and memory-efficient XML document processing. - However, since pugixml has a DOM parser, it can't process XML documents that - do not fit in memory; also the parser is a non-validating one, so if you - need DTD/Schema validation, the library is not for you. -

-

- This is the quick start guide for pugixml, which purpose is to enable you - to start using the library quickly. Many important library features are either - not described at all or only mentioned briefly; for more complete information - you should read the complete manual. -

-

	Note
	- No documentation is perfect, neither is this one. If you encounter a description - that is unclear, please file an issue as described in Feedback. Also if - you can spare the time for a full proof-reading, including spelling and - grammar, that would be great! Please send me an e-mail; - as a token of appreciation, your name will be included into the corresponding - section of the manual. -

-

- Installation -

-

- pugixml is distributed in source form. You can download a source distribution - via one of the following links: -

-

https://github.com/zeux/pugixml/releases/download/v1.6/pugixml-1.6.zip
-https://github.com/zeux/pugixml/releases/download/v1.6/pugixml-1.6.tar.gz
-

-

- The distribution contains library source, documentation (the guide you're - reading now and the manual) and some code examples. After downloading the - distribution, install pugixml by extracting all files from the compressed - archive. The files have different line endings depending on the archive format - - .zip archive has Windows line endings, .tar.gz archive has Unix line endings. - Otherwise the files in both archives are identical. -

-

- The complete pugixml source consists of three files - one source file, pugixml.cpp, - and two header files, pugixml.hpp and pugiconfig.hpp. pugixml.hpp is the primary - header which you need to include in order to use pugixml classes/functions. - The rest of this guide assumes that pugixml.hpp is either in the current directory - or in one of include directories of your projects, so that #include "pugixml.hpp" - can find the header; however you can also use relative path (i.e. #include "../libs/pugixml/src/pugixml.hpp") - or include directory-relative path (i.e. #include - <xml/thirdparty/pugixml/src/pugixml.hpp>). -

-

- The easiest way to build pugixml is to compile the source file, pugixml.cpp, - along with the existing library/executable. This process depends on the method - of building your application; for example, if you're using Microsoft Visual - Studio^[1], - Apple Xcode, Code::Blocks or any other IDE, just add pugixml.cpp to one of - your projects. There are other building methods available, including building - pugixml as a standalone static/shared library; read - the manual for further information. -

-

- Document object model -

-

- pugixml stores XML data in DOM-like way: the entire XML document (both document - structure and element data) is stored in memory as a tree. The tree can be - loaded from character stream (file, string, C++ I/O stream), then traversed - via special API or XPath expressions. The whole tree is mutable: both node - structure and node/attribute data can be changed at any time. Finally, the - result of document transformations can be saved to a character stream (file, - C++ I/O stream or custom transport). -

-

- The root of the tree is the document itself, which corresponds to C++ type - xml_document. Document has - one or more child nodes, which correspond to C++ type xml_node. - Nodes have different types; depending on a type, a node can have a collection - of child nodes, a collection of attributes, which correspond to C++ type - xml_attribute, and some additional - data (i.e. name). -

-

- The most common node types are: -

-

- Document node (node_document) - - this is the root of the tree, which consists of several child nodes. - This node corresponds to xml_document - class; note that xml_document - is a sub-class of xml_node, - so the entire node interface is also available. -
- Element/tag node (node_element) - - this is the most common type of node, which represents XML elements. - Element nodes have a name, a collection of attributes and a collection - of child nodes (both of which may be empty). The attribute is a simple - name/value pair. -
- Plain character data nodes (node_pcdata) - represent plain text in XML. PCDATA nodes have a value, but do not have - name or children/attributes. Note that plain character - data is not a part of the element node but instead has its own node; - for example, an element node can have several child PCDATA nodes. -

-

- Despite the fact that there are several node types, there are only three - C++ types representing the tree (xml_document, - xml_node, xml_attribute); - some operations on xml_node - are only valid for certain node types. They are described below. -

-

- - - - - -

	Note
	- All pugixml classes and functions are located in `pugi` - namespace; you have to either use explicit name qualification (i.e. `pugi::xml_node`), or to gain access to relevant - symbols via `using` directive - (i.e. `using pugi::xml_node;` or `using - namespace pugi;`). -

-

- xml_document is the owner - of the entire document structure; destroying the document destroys the whole - tree. The interface of xml_document - consists of loading functions, saving functions and the entire interface - of xml_node, which allows - for document inspection and/or modification. Note that while xml_document is a sub-class of xml_node, xml_node - is not a polymorphic type; the inheritance is present only to simplify usage. -

-

- xml_node is the handle to - document node; it can point to any node in the document, including document - itself. There is a common interface for nodes of all types. Note that xml_node is only a handle to the actual - node, not the node itself - you can have several xml_node - handles pointing to the same underlying object. Destroying xml_node handle does not destroy the node - and does not remove it from the tree. -

-

- There is a special value of xml_node - type, known as null node or empty node. It does not correspond to any node - in any document, and thus resembles null pointer. However, all operations - are defined on empty nodes; generally the operations don't do anything and - return empty nodes/attributes or empty strings as their result. This is useful - for chaining calls; i.e. you can get the grandparent of a node like so: - node.parent().parent(); - if a node is a null node or it does not have a parent, the first parent() - call returns null node; the second parent() call then also returns null node, so you - don't have to check for errors twice. You can test if a handle is null via - implicit boolean cast: if (node) { ... } - or if (!node) { ... }. -

-

- xml_attribute is the handle - to an XML attribute; it has the same semantics as xml_node, - i.e. there can be several xml_attribute - handles pointing to the same underlying object and there is a special null - attribute value, which propagates to function results. -

-

- There are two choices of interface and internal representation when configuring - pugixml: you can either choose the UTF-8 (also called char) interface or - UTF-16/32 (also called wchar_t) one. The choice is controlled via PUGIXML_WCHAR_MODE define; you can set - it via pugiconfig.hpp or via preprocessor options. All tree functions that - work with strings work with either C-style null terminated strings or STL - strings of the selected character type. Read - the manual for additional information on Unicode interface. -

-

- Loading document -

-

- pugixml provides several functions for loading XML data from various places - - files, C++ iostreams, memory buffers. All functions use an extremely fast - non-validating parser. This parser is not fully W3C conformant - it can load - any valid XML document, but does not perform some well-formedness checks. - While considerable effort is made to reject invalid XML documents, some validation - is not performed because of performance reasons. XML data is always converted - to internal character format before parsing. pugixml supports all popular - Unicode encodings (UTF-8, UTF-16 (big and little endian), UTF-32 (big and - little endian); UCS-2 is naturally supported since it's a strict subset of - UTF-16) and handles all encoding conversions automatically. -

-

- The most common source of XML data is files; pugixml provides a separate - function for loading XML document from file. This function accepts file path - as its first argument, and also two optional arguments, which specify parsing - options and input data encoding, which are described in the manual. -

-

- This is an example of loading XML document from file (samples/load_file.cpp): -

-

- -

-

pugi::xml_document doc;
-
-pugi::xml_parse_result result = doc.load_file("tree.xml");
-
-std::cout << "Load result: " << result.description() << ", mesh name: " << doc.child("mesh").attribute("name").value() << std::endl;
-

-

- load_file, as well as other - loading functions, destroys the existing document tree and then tries to - load the new tree from the specified file. The result of the operation is - returned in an xml_parse_result - object; this object contains the operation status, and the related information - (i.e. last successfully parsed position in the input file, if parsing fails). -

-

- Parsing result object can be implicitly converted to bool; - if you do not want to handle parsing errors thoroughly, you can just check - the return value of load functions as if it was a bool: - if (doc.load_file("file.xml")) { ... - } else { ... }. - Otherwise you can use the status - member to get parsing status, or the description() member function to get the status in a - string form. -

-

- This is an example of handling loading errors (samples/load_error_handling.cpp): -

-

- -

-

pugi::xml_document doc;
-pugi::xml_parse_result result = doc.load_string(source);
-
-if (result)
-    std::cout << "XML [" << source << "] parsed without errors, attr value: [" << doc.child("node").attribute("attr").value() << "]\n\n";
-else
-{
-    std::cout << "XML [" << source << "] parsed with errors, attr value: [" << doc.child("node").attribute("attr").value() << "]\n";
-    std::cout << "Error description: " << result.description() << "\n";
-    std::cout << "Error offset: " << result.offset << " (error at [..." << (source + result.offset) << "]\n\n";
-}
-

-

- Sometimes XML data should be loaded from some other source than file, i.e. - HTTP URL; also you may want to load XML data from file using non-standard - functions, i.e. to use your virtual file system facilities or to load XML - from gzip-compressed files. These scenarios either require loading document - from memory, in which case you should prepare a contiguous memory block with - all XML data and to pass it to one of buffer loading functions, or loading - document from C++ IOstream, in which case you should provide an object which - implements std::istream or std::wistream - interface. -

-

- There are different functions for loading document from memory; they treat - the passed buffer as either an immutable one (load_buffer), - a mutable buffer which is owned by the caller (load_buffer_inplace), - or a mutable buffer which ownership belongs to pugixml (load_buffer_inplace_own). - There is also a simple helper function, xml_document::load, - for cases when you want to load the XML document from null-terminated character - string. -

-

- This is an example of loading XML document from memory using one of these - functions (samples/load_memory.cpp); - read the sample code for more examples: -

-

- -

-

const char source[] = "<mesh name='sphere'><bounds>0 0 1 1</bounds></mesh>";
-size_t size = sizeof(source);
-

-

- -

-

// You can use load_buffer_inplace to load document from mutable memory block; the block's lifetime must exceed that of document
-char* buffer = new char[size];
-memcpy(buffer, source, size);
-
-// The block can be allocated by any method; the block is modified during parsing
-pugi::xml_parse_result result = doc.load_buffer_inplace(buffer, size);
-
-// You have to destroy the block yourself after the document is no longer used
-delete[] buffer;
-

-

- This is a simple example of loading XML document from file using streams - (samples/load_stream.cpp); read - the sample code for more complex examples involving wide streams and locales: -

-

- -

-

std::ifstream stream("weekly-utf-8.xml");
-pugi::xml_parse_result result = doc.load(stream);
-

-

- Accessing document data -

-

- pugixml features an extensive interface for getting various types of data - from the document and for traversing the document. You can use various accessors - to get node/attribute data, you can traverse the child node/attribute lists - via accessors or iterators, you can do depth-first traversals with xml_tree_walker objects, and you can use - XPath for complex data-driven queries. -

-

- You can get node or attribute name via name() accessor, and value via value() accessor. Note that both functions never - return null pointers - they either return a string with the relevant content, - or an empty string if name/value is absent or if the handle is null. Also - there are two notable things for reading values: -

-

- It is common to store data as text contents of some node - i.e. <node><description>This - is a - node</description></node>. - In this case, <description> node does not have a value, but instead - has a child of type node_pcdata - with value "This is a node". - pugixml provides child_value() and text() helper functions to parse such data. -
- In many cases attribute values have types that are not strings - i.e. - an attribute may always contain values that should be treated as integers, - despite the fact that they are represented as strings in XML. pugixml - provides several accessors that convert attribute value to some other - type. -

-

- This is an example of using these functions (samples/traverse_base.cpp): -

-

- -

-

for (pugi::xml_node tool = tools.child("Tool"); tool; tool = tool.next_sibling("Tool"))
-{
-    std::cout << "Tool " << tool.attribute("Filename").value();
-    std::cout << ": AllowRemote " << tool.attribute("AllowRemote").as_bool();
-    std::cout << ", Timeout " << tool.attribute("Timeout").as_int();
-    std::cout << ", Description '" << tool.child_value("Description") << "'\n";
-}
-

-

- Since a lot of document traversal consists of finding the node/attribute - with the correct name, there are special functions for that purpose. For - example, child("Tool") - returns the first node which has the name "Tool", - or null handle if there is no such node. This is an example of using such - functions (samples/traverse_base.cpp): -

-

- -

-

std::cout << "Tool for *.dae generation: " << tools.find_child_by_attribute("Tool", "OutputFileMasks", "*.dae").attribute("Filename").value() << "\n";
-
-for (pugi::xml_node tool = tools.child("Tool"); tool; tool = tool.next_sibling("Tool"))
-{
-    std::cout << "Tool " << tool.attribute("Filename").value() << "\n";
-}
-

-

- Child node lists and attribute lists are simply double-linked lists; while - you can use previous_sibling/next_sibling and other such functions for - iteration, pugixml additionally provides node and attribute iterators, so - that you can treat nodes as containers of other nodes or attributes. All - iterators are bidirectional and support all usual iterator operations. The - iterators are invalidated if the node/attribute objects they're pointing - to are removed from the tree; adding nodes/attributes does not invalidate - any iterators. -

-

- Here is an example of using iterators for document traversal (samples/traverse_iter.cpp): -

-

- -

-

for (pugi::xml_node_iterator it = tools.begin(); it != tools.end(); ++it)
-{
-    std::cout << "Tool:";
-
-    for (pugi::xml_attribute_iterator ait = it->attributes_begin(); ait != it->attributes_end(); ++ait)
-    {
-        std::cout << " " << ait->name() << "=" << ait->value();
-    }
-
-    std::cout << std::endl;
-}
-

-

- If your C++ compiler supports range-based for-loop (this is a C++11 feature, - at the time of writing it's supported by Microsoft Visual Studio 11 Beta, - GCC 4.6 and Clang 3.0), you can use it to enumerate nodes/attributes. Additional - helpers are provided to support this; note that they are also compatible - with Boost Foreach, - and possibly other pre-C++11 foreach facilities. -

-

- Here is an example of using C++11 range-based for loop for document traversal - (samples/traverse_rangefor.cpp): -

-

- -

-

for (pugi::xml_node tool: tools.children("Tool"))
-{
-    std::cout << "Tool:";
-
-    for (pugi::xml_attribute attr: tool.attributes())
-    {
-        std::cout << " " << attr.name() << "=" << attr.value();
-    }
-
-    for (pugi::xml_node child: tool.children())
-    {
-        std::cout << ", child " << child.name();
-    }
-
-    std::cout << std::endl;
-}
-

-

- The methods described above allow traversal of immediate children of some - node; if you want to do a deep tree traversal, you'll have to do it via a - recursive function or some equivalent method. However, pugixml provides a - helper for depth-first traversal of a subtree. In order to use it, you have - to implement xml_tree_walker - interface and to call traverse - function. -

-

- This is an example of traversing tree hierarchy with xml_tree_walker (samples/traverse_walker.cpp): -

-

- -

-

struct simple_walker: pugi::xml_tree_walker
-{
-    virtual bool for_each(pugi::xml_node& node)
-    {
-        for (int i = 0; i < depth(); ++i) std::cout << "  "; // indentation
-
-        std::cout << node_types[node.type()] << ": name='" << node.name() << "', value='" << node.value() << "'\n";
-
-        return true; // continue traversal
-    }
-};
-

-

- -

-

simple_walker walker;
-doc.traverse(walker);
-

-

- Finally, for complex queries often a higher-level DSL is needed. pugixml - provides an implementation of XPath 1.0 language for such queries. The complete - description of XPath usage can be found in the manual, but here are some - examples: -

-

- -

-

pugi::xpath_node_set tools = doc.select_nodes("/Profile/Tools/Tool[@AllowRemote='true' and @DeriveCaptionFrom='lastparam']");
-
-std::cout << "Tools:\n";
-
-for (pugi::xpath_node_set::const_iterator it = tools.begin(); it != tools.end(); ++it)
-{
-    pugi::xpath_node node = *it;
-    std::cout << node.node().attribute("Filename").value() << "\n";
-}
-
-pugi::xpath_node build_tool = doc.select_node("//Tool[contains(Description, 'build system')]");
-
-if (build_tool)
-    std::cout << "Build tool: " << build_tool.node().attribute("Filename").value() << "\n";
-

-

- - - - - -

	Caution
	- XPath functions throw `xpath_exception` - objects on error; the sample above does not catch these exceptions. -

-

- Modifying document data -

-

- The document in pugixml is fully mutable: you can completely change the document - structure and modify the data of nodes/attributes. All functions take care - of memory management and structural integrity themselves, so they always - result in structurally valid tree - however, it is possible to create an - invalid XML tree (for example, by adding two attributes with the same name - or by setting attribute/node name to empty/invalid string). Tree modification - is optimized for performance and for memory consumption, so if you have enough - memory you can create documents from scratch with pugixml and later save - them to file/stream instead of relying on error-prone manual text writing - and without too much overhead. -

-

- All member functions that change node/attribute data or structure are non-constant - and thus can not be called on constant handles. However, you can easily convert - constant handle to non-constant one by simple assignment: void - foo(const pugi::xml_node& n) { pugi::xml_node nc = n; }, so const-correctness - here mainly provides additional documentation. -

-

- As discussed before, nodes can have name and value, both of which are strings. - Depending on node type, name or value may be absent. You can use set_name and set_value - member functions to set them. Similar functions are available for attributes; - however, the set_value function - is overloaded for some other types except strings, like floating-point numbers. - Also, attribute value can be set using an assignment operator. This is an - example of setting node/attribute name and value (samples/modify_base.cpp): -

-

- -

-

pugi::xml_node node = doc.child("node");
-
-// change node name
-std::cout << node.set_name("notnode");
-std::cout << ", new node name: " << node.name() << std::endl;
-
-// change comment text
-std::cout << doc.last_child().set_value("useless comment");
-std::cout << ", new comment text: " << doc.last_child().value() << std::endl;
-
-// we can't change value of the element or name of the comment
-std::cout << node.set_value("1") << ", " << doc.last_child().set_name("2") << std::endl;
-

-

- -

-

pugi::xml_attribute attr = node.attribute("id");
-
-// change attribute name/value
-std::cout << attr.set_name("key") << ", " << attr.set_value("345");
-std::cout << ", new attribute: " << attr.name() << "=" << attr.value() << std::endl;
-
-// we can use numbers or booleans
-attr.set_value(1.234);
-std::cout << "new attribute value: " << attr.value() << std::endl;
-
-// we can also use assignment operators for more concise code
-attr = true;
-std::cout << "final attribute value: " << attr.value() << std::endl;
-

-

- Nodes and attributes do not exist without a document tree, so you can't create - them without adding them to some document. A node or attribute can be created - at the end of node/attribute list or before/after some other node. All insertion - functions return the handle to newly created object on success, and null - handle on failure. Even if the operation fails (for example, if you're trying - to add a child node to PCDATA node), the document remains in consistent state, - but the requested node/attribute is not added. -

-

- - - - - -

	Caution
	- attribute() and child() functions do not add attributes or nodes to the - tree, so code like `node.attribute("id") = 123;` will not do anything if `node` does not have an attribute with - name `"id"`. Make sure - you're operating with existing attributes/nodes by adding them if necessary. -

-

- This is an example of adding new attributes/nodes to the document (samples/modify_add.cpp): -

-

- -

-

// add node with some name
-pugi::xml_node node = doc.append_child("node");
-
-// add description node with text child
-pugi::xml_node descr = node.append_child("description");
-descr.append_child(pugi::node_pcdata).set_value("Simple node");
-
-// add param node before the description
-pugi::xml_node param = node.insert_child_before("param", descr);
-
-// add attributes to param node
-param.append_attribute("name") = "version";
-param.append_attribute("value") = 1.1;
-param.insert_attribute_after("type", param.attribute("name")) = "float";
-

-

- If you do not want your document to contain some node or attribute, you can - remove it with remove_attribute - and remove_child functions. - Removing the attribute or node invalidates all handles to the same underlying - object, and also invalidates all iterators pointing to the same object. Removing - node also invalidates all past-the-end iterators to its attribute or child - node list. Be careful to ensure that all such handles and iterators either - do not exist or are not used after the attribute/node is removed. -

-

- This is an example of removing attributes/nodes from the document (samples/modify_remove.cpp): -

-

- -

-

// remove description node with the whole subtree
-pugi::xml_node node = doc.child("node");
-node.remove_child("description");
-
-// remove id attribute
-pugi::xml_node param = node.child("param");
-param.remove_attribute("value");
-
-// we can also remove nodes/attributes by handles
-pugi::xml_attribute id = param.attribute("name");
-param.remove_attribute(id);
-

-

- Saving document -

-

- Often after creating a new document or loading the existing one and processing - it, it is necessary to save the result back to file. Also it is occasionally - useful to output the whole document or a subtree to some stream; use cases - include debug printing, serialization via network or other text-oriented - medium, etc. pugixml provides several functions to output any subtree of - the document to a file, stream or another generic transport interface; these - functions allow to customize the output format, and also perform necessary - encoding conversions. -

-

- Before writing to the destination the node/attribute data is properly formatted - according to the node type; all special XML symbols, such as < and &, - are properly escaped. In order to guard against forgotten node/attribute - names, empty node/attribute names are printed as ":anonymous". - For well-formed output, make sure all node and attribute names are set to - meaningful values. -

-

- If you want to save the whole document to a file, you can use the save_file function, which returns true on success. This is a simple example - of saving XML document to file (samples/save_file.cpp): -

-

- -

-

// save document to file
-std::cout << "Saving result: " << doc.save_file("save_file_output.xml") << std::endl;
-

-

- To enhance interoperability pugixml provides functions for saving document - to any object which implements C++ std::ostream - interface. This allows you to save documents to any standard C++ stream (i.e. - file stream) or any third-party compliant implementation (i.e. Boost Iostreams). - Most notably, this allows for easy debug output, since you can use std::cout - stream as saving target. There are two functions, one works with narrow character - streams, another handles wide character ones. -

-

- This is a simple example of saving XML document to standard output (samples/save_stream.cpp): -

-

- -

-

// save document to standard output
-std::cout << "Document:\n";
-doc.save(std::cout);
-

-

- All of the above saving functions are implemented in terms of writer interface. - This is a simple interface with a single function, which is called several - times during output process with chunks of document data as input. In order - to output the document via some custom transport, for example sockets, you - should create an object which implements xml_writer_file - interface and pass it to xml_document::save - function. -

-

- This is a simple example of custom writer for saving document data to STL - string (samples/save_custom_writer.cpp); - read the sample code for more complex examples: -

-

- -

-

struct xml_string_writer: pugi::xml_writer
-{
-    std::string result;
-
-    virtual void write(const void* data, size_t size)
-    {
-        result.append(static_cast<const char*>(data), size);
-    }
-};
-

-

- While the previously described functions save the whole document to the destination, - it is easy to save a single subtree. Instead of calling xml_document::save, - just call xml_node::print function on the target node. You - can save node contents to C++ IOstream object or custom writer in this way. - Saving a subtree slightly differs from saving the whole document; read the manual for - more information. -
