Detailed Description

A Document binds together all the functionality. It can be saved, loaded, and printed to the screen. All Nodes are connected and allocated to a Document. If the Document is deleted, all its Nodes are also deleted.

Member Function Documentation

bool BT_TinyXML2::XMLDocument::Accept ( XMLVisitor * visitor ) const [virtual]

Accept a hierarchical visit of the nodes in the TinyXML-2 DOM. Every node in the XML tree will be conditionally visited and the host will be called back via the XMLVisitor interface.

This is essentially a SAX interface for TinyXML-2. (Note however it doesn't re-parse the XML for the callbacks, so the performance of TinyXML-2 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():

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

Implements BT_TinyXML2::XMLNode.

void BT_TinyXML2::XMLDocument::DeepCopy ( XMLDocument * target ) const

XMLError BT_TinyXML2::XMLDocument::LoadFile ( FILE * fp )

Load an XML file from disk. You are responsible for providing and closing the FILE*.

XMLError BT_TinyXML2::XMLDocument::Parse	(	const char *	xml,
		size_t	nBytes = `(size_t)(-1)`
	)

Parse an XML file from a character string. Returns XML_SUCCESS (0) on success, or an errorID.

You may optionally pass in the 'nBytes', which is the number of bytes which will be parsed. If not specified, TinyXML-2 will assume 'xml' points to a null terminated string.

Print the Document. If the Printer is not provided, it will print to stdout. If you provide Printer, this can print to a file:

    	XMLPrinter printer( fp );
    	doc.Print( &printer );

Or you can use a printer to print to memory:

    	XMLPrinter printer;
    	doc.Print( &printer );
    	// printer.CStr() has a const char* to the XML

virtual XMLNode* BT_TinyXML2::XMLDocument::ShallowClone ( XMLDocument * document ) const [inline, virtual]

Make a copy of this node, but not its children. You may pass in a Document pointer that will be the owner of the new Node. If the 'document' is null, then the node returned will be allocated from the current Document. (this->GetDocument())
