Detailed Description

The parent class for everything in the Document Object Model. (Except for attributes). Nodes have siblings, a parent, and children. A node can be in a document, or stand on its own. The type of a TiXmlNode can be queried, and it can be cast to its more defined type.

virtual bool TiXmlNode::Accept ( TiXmlVisitor visitor ) const [pure virtual]

Accept a hierchical visit the nodes in the TinyXML DOM. Every node in the XML tree will be conditionally visited and the host will be called back via the TiXmlVisitor interface.

This is essentially a SAX interface for TinyXML. (Note however it doesn't re-parse the XML for the callbacks, so the performance of TinyXML is unchanged by using this interface versus any other.)

The interface has been based on ideas from:

Which are both good references for "visiting".

An example of using Accept():

		TiXmlPrinter printer;
		tinyxmlDoc.Accept( &printer );
		const char* xmlcstr = printer.CStr();
		

Implemented in TiXmlElement, TiXmlComment, TiXmlText, TiXmlDeclaration, TiXmlUnknown, and TiXmlDocument.

const TiXmlNode * TiXmlNode::IterateChildren ( const TiXmlNode previous ) const

An alternate way to walk the children of a node. One way to iterate over nodes is:

			for( child = parent->FirstChild(); child; child = child->NextSibling() )
		

IterateChildren does the same thing with the syntax:

			child = 0;
			while( child = parent->IterateChildren( child ) )
		

IterateChildren takes the previous child as input and finds the next one. If the previous child is null, it returns the first. IterateChildren will return null when done.

std::ostream& operator<< ( std::ostream &  out,
const TiXmlNode base 
) [friend]

An output stream operator, for every class. Note that this outputs without any newlines or formatting, as opposed to Print(), which includes tabs and new lines.

The operator<< and operator>> are not completely symmetric. Writing a node to a stream is very well defined. You'll get a nice stream of output, without any extra whitespace or newlines.

But reading is not as well defined. (As it always is.) If you create a TiXmlElement (for example) and read that from an input stream, the text needs to define an element or junk will result. This is true of all input streams, but it's worth keeping in mind.

A TiXmlDocument will read nodes until it reads a root element, and all the children of that root element.
