Detailed Description

The parent class for everything in the Document Object Model. (Except for attributes). Nodes have siblings, a parent, and children. A node can be in a document, or stand on its own. The type of a TiXmlNode can be queried, and it can be cast to its more defined type.

Member Enumeration Documentation

enum TiXmlNode::NodeType

The types of XML nodes supported by TinyXml. (All the unsupported types are picked up by UNKNOWN.)

Member Function Documentation

virtual TiXmlNode* TiXmlNode::Clone (   )  const [pure virtual]

Create an exact duplicate of this node and return it. The memory must be deleted by the caller. Implemented in TiXmlElement, TiXmlComment, TiXmlText, TiXmlDeclaration, TiXmlUnknown, and TiXmlDocument.

const TiXmlDocument* TiXmlNode::GetDocument (   )  const

Return a pointer to the Document this node lives in. Returns null if not in a document.

TiXmlNode* TiXmlNode::InsertAfterChild (  TiXmlNode *  afterThis, const TiXmlNode &  addThis )

Add a new node related to this. Adds a child after the specified child. Returns a pointer to the new object or NULL if an error occured.

TiXmlNode* TiXmlNode::InsertBeforeChild (  TiXmlNode *  beforeThis, const TiXmlNode &  addThis )

Add a new node related to this. Adds a child before the specified child. Returns a pointer to the new object or NULL if an error occured.

TiXmlNode* TiXmlNode::InsertEndChild (  const TiXmlNode &  addThis  )

Add a new node related to this. Adds a child past the LastChild. Returns a pointer to the new object or NULL if an error occured.

const TiXmlNode* TiXmlNode::IterateChildren (  TiXmlNode *  previous  )  const

An alternate way to walk the children of a node. One way to iterate over nodes is: for( child = parent->FirstChild(); child; child = child->NextSibling() ) IterateChildren does the same thing with the syntax: child = 0; while( child = parent->IterateChildren( child ) ) IterateChildren takes the previous child as input and finds the next one. If the previous child is null, it returns the first. IterateChildren will return null when done.

TiXmlNode* TiXmlNode::LinkEndChild (  TiXmlNode *  addThis  )

Add a new node related to this. Adds a child past the LastChild. NOTE: the node to be added is passed by pointer, and will be henceforth owned (and deleted) by tinyXml. This method is efficient and avoids an extra copy, but should be used with care as it uses a different memory model than the other insert functions. See also: InsertEndChild

const TiXmlElement* TiXmlNode::NextSiblingElement (  const char *   )  const

Convenience function to get through elements. Calls NextSibling and ToElement. Will skip all non-Element nodes. Returns 0 if there is not another element.

const TiXmlElement* TiXmlNode::NextSiblingElement (   )  const

Convenience function to get through elements. Calls NextSibling and ToElement. Will skip all non-Element nodes. Returns 0 if there is not another element.

TiXmlNode* TiXmlNode::ReplaceChild (  TiXmlNode *  replaceThis, const TiXmlNode &  withThis )

Replace a child of this node. Returns a pointer to the new object or NULL if an error occured.

void TiXmlNode::SetValue (  const char *  _value  )  [inline]

Changes the value of the node. Defined as: Document: filename of the xml file Element: name of the element Comment: the comment text Unknown: the tag contents Text: the text string

virtual int TiXmlNode::Type (   )  const [inline, virtual]

Query the type (as an enumerated value, above) of this node. The possible types are: DOCUMENT, ELEMENT, COMMENT, UNKNOWN, TEXT, and DECLARATION.

const char* TiXmlNode::Value (   )  const [inline]

The meaning of 'value' changes for the specific type of TiXmlNode. Document: filename of the xml file Element: name of the element Comment: the comment text Unknown: the tag contents Text: the text string The subclasses will wrap this function.
