Detailed Description

An attribute is a name-value pair. Elements have an arbitrary number of attributes, each with a unique name.

Note:: The attributes are not TiXmlNodes, since they are not part of the tinyXML document object model. There are other suggested ways to look at this problem.

virtual void TiXmlAttribute::Print	(	FILE *	cfile,
		int	depth
	)		const `[inline, virtual]`

All TinyXml classes can print themselves to a filestream or the string class (TiXmlString in non-STL mode, std::string in STL mode.) Either or both cfile and str can be null.

This is a formatted print, and will insert tabs and newlines.

(For an unformatted stream, use the << operator.)

Implements TiXmlBase.

QueryDoubleValue examines the value string. See QueryIntValue().

Here is the caller graph for this function:

int TiXmlAttribute::QueryIntValue ( int * _value ) const

QueryIntValue examines the value string. It is an alternative to the IntValue() method with richer error checking. If the value is an integer, it is stored in 'value' and the call returns TIXML_SUCCESS. If it is not an integer, it returns TIXML_WRONG_TYPE.

A specialized but useful call. Note that for success it returns 0, which is the opposite of almost all other TinyXml calls.

        if ( TIXML_SSCANF( value.c_str(), "%d", ival ) == 1 )
