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.

Member Function Documentation

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.

void TiXmlNode::Clear ( )

Delete all the children of this node. Does not affect 'this'.

Definition at line 169 of file tinyxml.cpp.

{
        TiXmlNode* node = firstChild;
        TiXmlNode* temp = 0;

        while ( node )

                temp = node;
                node = node->next;
                delete temp;
        }       

        firstChild = 0;
        lastChild = 0;
}

Here is the caller graph for this function:

virtual TiXmlNode* TiXmlNode::Clone ( ) const [pure virtual]

Create an exact duplicate of this node and return it. The memory must be deleted by the caller.

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

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.

TiXmlNode * TiXmlNode::LinkEndChild ( TiXmlNode * addThis )

Add a new node related to this. Adds a child past the LastChild.

NOTE: the node to be added is passed by pointer, and will be henceforth owned (and deleted) by tinyXml. This method is efficient and avoids an extra copy, but should be used with care as it uses a different memory model than the other insert functions.
