Detailed Description

A light-weight wrapper for manipulating attributes in DOM tree.

Note: xml_attribute does not allocate any memory for the attribute it wraps; it only wraps a pointer to existing attribute.

Default ctor. Constructs an empty attribute.

Member Function Documentation

pugi::xml_attribute::operator unspecified_bool_type (   )  const

Safe bool conversion. Allows xml_node to be used in a context where boolean variable is expected, such as 'if (node)'.

bool pugi::xml_attribute::operator== (  const xml_attribute &  r  )  const

Compare wrapped pointer to the attribute to the pointer that is wrapped by r. Parameters: r  - value to compare to Returns: comparison result

bool pugi::xml_attribute::operator!= (  const xml_attribute &  r  )  const

Compare wrapped pointer to the attribute to the pointer that is wrapped by r. Parameters: r  - value to compare to Returns: comparison result

bool pugi::xml_attribute::operator< (  const xml_attribute &  r  )  const

Compare wrapped pointer to the attribute to the pointer that is wrapped by r. Parameters: r  - value to compare to Returns: comparison result

bool pugi::xml_attribute::operator> (  const xml_attribute &  r  )  const

Compare wrapped pointer to the attribute to the pointer that is wrapped by r. Parameters: r  - value to compare to Returns: comparison result

bool pugi::xml_attribute::operator<= (  const xml_attribute &  r  )  const

Compare wrapped pointer to the attribute to the pointer that is wrapped by r. Parameters: r  - value to compare to Returns: comparison result

bool pugi::xml_attribute::operator>= (  const xml_attribute &  r  )  const

Compare wrapped pointer to the attribute to the pointer that is wrapped by r. Parameters: r  - value to compare to Returns: comparison result

xml_attribute pugi::xml_attribute::next_attribute (   )  const

Get next attribute in attribute list of node that contains the attribute. Returns: next attribute, if any; empty attribute otherwise

xml_attribute pugi::xml_attribute::previous_attribute (   )  const

Get previous attribute in attribute list of node that contains the attribute. Returns: previous attribute, if any; empty attribute otherwise

int pugi::xml_attribute::as_int (   )  const

Cast attribute value as int. Returns: attribute value as int, or 0 if conversion did not succeed or attribute is empty

unsigned int pugi::xml_attribute::as_uint (   )  const

Cast attribute value as unsigned int. Returns: attribute value as unsigned int, or 0 if conversion did not succeed or attribute is empty Note: values out of non-negative int range (usually [0, 2^31-1]) get clamped to range boundaries

double pugi::xml_attribute::as_double (   )  const

Cast attribute value as double. Returns: attribute value as double, or 0.0 if conversion did not succeed or attribute is empty

float pugi::xml_attribute::as_float (   )  const

Cast attribute value as float. Returns: attribute value as float, or 0.0f if conversion did not succeed or attribute is empty

bool pugi::xml_attribute::as_bool (   )  const

Cast attribute value as bool. Returns true for attributes with values that start with '1', 't', 'T', 'y', 'Y', returns false for other attributes. Returns: attribute value as bool, or false if conversion did not succeed or attribute is empty

xml_attribute& pugi::xml_attribute::operator= (  const char *  rhs  )

Set attribute value to rhs. Parameters: rhs  - new attribute value Returns: self

xml_attribute& pugi::xml_attribute::operator= (  int  rhs  )

Set attribute value to rhs. Parameters: rhs  - new attribute value Returns: self

xml_attribute& pugi::xml_attribute::operator= (  bool  rhs  )

Set attribute value to either 'true' or 'false' (depends on whether rhs is true or false). Parameters: rhs  - new attribute value Returns: self

bool pugi::xml_attribute::set_name (  const char *  rhs  )

Set attribute name to rhs. Parameters: rhs  - new attribute name Returns: success flag (call fails if attribute is empty or there is not enough memory)

bool pugi::xml_attribute::set_value (  const char *  rhs  )

Set attribute value to rhs. Parameters: rhs  - new attribute value Returns: success flag (call fails if attribute is empty or there is not enough memory)

bool pugi::xml_attribute::set_value (  int  rhs  )

Set attribute value to rhs. Parameters: rhs  - new attribute value Returns: success flag (call fails if attribute is empty or there is not enough memory)

bool pugi::xml_attribute::set_value (  double  rhs  )

Set attribute value to rhs. Parameters: rhs  - new attribute value Returns: success flag (call fails if attribute is empty or there is not enough memory)

bool pugi::xml_attribute::set_value (  bool  rhs  )

Set attribute value to either 'true' or 'false' (depends on whether rhs is true or false). Parameters: rhs  - new attribute value Returns: success flag (call fails if attribute is empty or there is not enough memory)

bool pugi::xml_attribute::empty (   )  const

Check if attribute is empty. Returns: true if attribute is empty, false otherwise

const char* pugi::xml_attribute::name (   )  const

Get attribute name. Returns: attribute name, or "" if attribute is empty

const char* pugi::xml_attribute::value (   )  const

Get attribute value. Returns: attribute value, or "" if attribute is empty
