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.

◆ DeepClone()

XMLNode * tinyxml2::XMLNode::DeepClone ( XMLDocument * target ) const

Make a copy of this node and all its children.

If the 'target' is null, then the nodes will be allocated in the current document. If 'target' is specified, the memory will be allocated is the specified XMLDocument.

NOTE: This is probably not the correct tool to copy a document, since XMLDocuments can have multiple top level XMLNodes. You probably want to use XMLDocument::DeepCopy()

◆ DeleteChild()

void tinyxml2::XMLNode::DeleteChild ( XMLNode * node )

Delete a child of this node.

◆ DeleteChildren()

void tinyxml2::XMLNode::DeleteChildren ( )

Delete all the children of this node.

◆ FirstChildElement()

const XMLElement * tinyxml2::XMLNode::FirstChildElement ( const char * name = 0 ) const

Get the first child element, or optionally the first child element with the specified name.

◆ GetUserData()

void * tinyxml2::XMLNode::GetUserData ( ) const

inline

Get user data set into the XMLNode. TinyXML-2 in no way processes or interprets user data. It is initially 0.

◆ InsertAfterChild()

XMLNode * tinyxml2::XMLNode::InsertAfterChild	(	XMLNode *	afterThis,
		XMLNode *	addThis )

Add a node after the specified child node. If the child node is already part of the document, it is moved from its old location to the new location. Returns the addThis argument or 0 if the afterThis node is not a child of this node, or if the node does not belong to the same document.

◆ InsertEndChild()

XMLNode * tinyxml2::XMLNode::InsertEndChild ( XMLNode * addThis )

Add a child node as the last (right) child. If the child node is already part of the document, it is moved from its old location to the new location. Returns the addThis argument or 0 if the node does not belong to the same document.

◆ InsertFirstChild()

XMLNode * tinyxml2::XMLNode::InsertFirstChild ( XMLNode * addThis )

Add a child node as the first (left) child. If the child node is already part of the document, it is moved from its old location to the new location. Returns the addThis argument or 0 if the node does not belong to the same document.

◆ LastChildElement()

const XMLElement * tinyxml2::XMLNode::LastChildElement ( const char * name = 0 ) const

Get the last child element or optionally the last child element with the specified name.

◆ SetUserData()

void tinyxml2::XMLNode::SetUserData ( void * userData )

inline

Set user data into the XMLNode. TinyXML-2 in no way processes or interprets user data. It is initially 0.

◆ SetValue()

void tinyxml2::XMLNode::SetValue	(	const char *	val,
		bool	staticMem = false )

Set the Value of an XML node.

See also: Value()

◆ 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.

◆ Value()

const char * tinyxml2::XMLNode::Value ( ) const

The meaning of 'value' changes for the specific type.

Document:   empty (NULL is returned, not an empty string)
Element:    name of the element
Comment:    the comment text
Unknown:    the tag contents
Text:       the text string
