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-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::XMLDocument, tinyxml2::XMLElement, tinyxml2::XMLUnknown, tinyxml2::XMLDeclaration, tinyxml2::XMLComment, and tinyxml2::XMLText.

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

Delete a child of this node.

void tinyxml2::XMLNode::DeleteChildren ( )

Delete all the children of this node.

const XMLNode* tinyxml2::XMLNode::FirstChild ( ) const
inline

Get the first child node, or null if none exists.

XMLNode* tinyxml2::XMLNode::FirstChild ( )
inline
const XMLElement* tinyxml2::XMLNode::FirstChildElement ( const char *  value = 0) const

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

XMLElement* tinyxml2::XMLNode::FirstChildElement ( const char *  value = 0)
inline
const XMLDocument* tinyxml2::XMLNode::GetDocument ( ) const
inline

Get the XMLDocument that owns this XMLNode.

XMLDocument* tinyxml2::XMLNode::GetDocument ( )
inline

Get the XMLDocument that owns this XMLNode.

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.

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.

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.

const XMLNode* tinyxml2::XMLNode::LastChild ( ) const
inline

Get the last child node, or null if none exists.

XMLNode* tinyxml2::XMLNode::LastChild ( )
inline
const XMLElement* tinyxml2::XMLNode::LastChildElement ( const char *  value = 0) const

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

XMLElement* tinyxml2::XMLNode::LastChildElement ( const char *  value = 0)
inline
XMLNode* tinyxml2::XMLNode::LinkEndChild ( XMLNode addThis)
inline
const XMLNode* tinyxml2::XMLNode::NextSibling ( ) const
inline

Get the next (right) sibling node of this node.

XMLNode* tinyxml2::XMLNode::NextSibling ( )
inline
const XMLElement* tinyxml2::XMLNode::NextSiblingElement ( const char *  value = 0) const

Get the next (right) sibling element of this node, with an optionally supplied name.

XMLElement* tinyxml2::XMLNode::NextSiblingElement ( const char *  value = 0)
inline
bool tinyxml2::XMLNode::NoChildren ( ) const
inline

Returns true if this node has no children.

XMLNode& tinyxml2::XMLNode::operator= ( const XMLNode )
protected
const XMLNode* tinyxml2::XMLNode::Parent ( ) const
inline

Get the parent of this node on the DOM.

XMLNode* tinyxml2::XMLNode::Parent ( )
inline
virtual char* tinyxml2::XMLNode::ParseDeep ( char *  ,
StrPair  
)
virtual
const XMLNode* tinyxml2::XMLNode::PreviousSibling ( ) const
inline

Get the previous (left) sibling node of this node.

XMLNode* tinyxml2::XMLNode::PreviousSibling ( )
inline
const XMLElement* tinyxml2::XMLNode::PreviousSiblingElement ( const char *  value = 0) const

Get the previous (left) sibling element of this node, with an optionally supplied name.

XMLElement* tinyxml2::XMLNode::PreviousSiblingElement ( const char *  value = 0)
inline
void tinyxml2::XMLNode::SetValue ( const char *  val,
bool  staticMem = false 
)

Set the Value of an XML node.

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.

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

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::XMLElement, tinyxml2::XMLUnknown, tinyxml2::XMLDeclaration, tinyxml2::XMLComment, and tinyxml2::XMLText.
