+[#xml_node::children][#xml_node::attributes]
+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 [@http://www.boost.org/libs/foreach/ Boost Foreach], and possibly other pre-C++11 foreach facilities.

+ ``/implementation-defined type/`` xml_node::attributes() const;
+
+`children` function allows you to enumerate all child nodes; `children` function with `name` argument allows you to enumerate all child nodes with a specific name; `attributes` function allows you to enumerate all attributes of the node. Note that you can also use node object itself in a range-based for construct, which is equivalent to using `children()`.
