Detailed Description

XMLNode is a base class for every object that is in the XML Document Object Model (DOM), except XMLAttributes. Nodes have siblings, a parent, and children which can be navigated. A node is always in a XMLDocument. The type of a XMLNode can be queried, and it can be cast to its more defined type.

A XMLDocument allocates memory for all its Nodes. When the XMLDocument gets deleted, all its Nodes will also be deleted.

A Document can contain: Element (container or leaf)
                        Comment (leaf)
                        Unknown (leaf)
                        Declaration( leaf )

An Element can contain: Element (container or leaf)
                        Text    (leaf)
                        Attributes (not on tree)
                        Comment (leaf)
                        Unknown (leaf)

Member Function Documentation

◆ Accept()

virtual bool tinyxml2::XMLNode::Accept ( XMLVisitor visitor) const
pure 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();

Implemented in tinyxml2::XMLText, tinyxml2::XMLComment, tinyxml2::XMLDeclaration, tinyxml2::XMLUnknown, tinyxml2::XMLElement, and tinyxml2::XMLDocument.

◆ ShallowClone()

virtual XMLNode * tinyxml2::XMLNode::ShallowClone ( XMLDocument document) const
pure 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())

Note: if called on a XMLDocument, this will return null.

Implemented in tinyxml2::XMLDocument, tinyxml2::XMLText, tinyxml2::XMLComment, tinyxml2::XMLDeclaration, tinyxml2::XMLUnknown, and tinyxml2::XMLElement.

◆ ShallowEqual()

virtual bool tinyxml2::XMLNode::ShallowEqual ( const XMLNode compare) const
pure virtual

Test if 2 nodes are the same, but don't test children. The 2 nodes do not need to be in the same Document.

Note: if called on a XMLDocument, this will return false.

Implemented in tinyxml2::XMLDocument, tinyxml2::XMLText, tinyxml2::XMLComment, tinyxml2::XMLDeclaration, tinyxml2::XMLUnknown, and tinyxml2::XMLElement.
