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

virtual bool tinyxml2::XMLNode::accept ( XMLVisitor visitor) const
pure virtual

Accept a hierarchical visit of 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 tinyxml2::XMLDocument, tinyxml2::XMLElement, tinyxml2::XMLUnknown, tinyxml2::XMLDeclaration, tinyxml2::XMLComment, and tinyxml2::XMLText.

Value()
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.
