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.

Constructor & Destructor Documentation

virtual TiXmlNode::~TiXmlNode ( ) [virtual]

TiXmlNode::TiXmlNode ( NodeType _type ) [protected]

Member Function Documentation

virtual bool TiXmlNode::Accept ( TiXmlVisitor * visitor ) const [pure virtual]

Accept a hierchical visit 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 TiXmlElement, TiXmlComment, TiXmlText, TiXmlDeclaration, TiXmlUnknown, and TiXmlDocument.

TiXmlNode* TiXmlNode::IterateChildren	(	const char *	_value,
		const TiXmlNode *	previous
	)			`[inline]`

const TiXmlNode* TiXmlNode::IterateChildren	(	const char *	value,
		const TiXmlNode *	previous
	)			const

This flavor of IterateChildren searches for children with a particular 'value'.

TiXmlNode* TiXmlNode::IterateChildren ( const TiXmlNode * previous ) [inline]

const TiXmlNode* TiXmlNode::IterateChildren ( const 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::LastChild ( const char * _value ) [inline]

The last child of this node matching 'value'. Will be null if there are no children.

const TiXmlNode* TiXmlNode::LastChild ( const char * value ) const

TiXmlNode* TiXmlNode::LastChild ( ) [inline]

The last child of this node. Will be null if there are no children.

const TiXmlNode* TiXmlNode::LastChild ( ) const [inline]

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

TiXmlNode* TiXmlNode::NextSibling ( const char * _next ) [inline]

const TiXmlNode* TiXmlNode::NextSibling ( const char * ) const

Navigate to a sibling node with the given 'value'.

TiXmlNode* TiXmlNode::NextSibling ( ) [inline]

const TiXmlNode* TiXmlNode::NextSibling ( ) const [inline]

TiXmlElement* TiXmlNode::NextSiblingElement ( const char * _next ) [inline]

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.

TiXmlElement* TiXmlNode::NextSiblingElement ( ) [inline]

const TiXmlElement* TiXmlNode::NextSiblingElement ( ) const

Convenience function to get through elements.

bool TiXmlNode::NoChildren ( ) const [inline]

Returns true if this node has no children.

const TiXmlNode* TiXmlNode::Parent ( ) const [inline]

TiXmlNode* TiXmlNode::Parent ( ) [inline]

One step up the DOM.

virtual const char* TiXmlBase::Parse	(	const char *	p,
		TiXmlParsingData *	data,
		TiXmlEncoding	encoding
	)			`[pure virtual, inherited]`

Implemented in TiXmlAttribute, TiXmlElement, TiXmlComment, TiXmlText, TiXmlDeclaration, TiXmlUnknown, and TiXmlDocument.

TiXmlNode* TiXmlNode::PreviousSibling ( ) [inline]

const TiXmlNode* TiXmlNode::PreviousSibling ( ) const [inline]

virtual void TiXmlBase::Print	(	FILE *	cfile,
		int	depth
	)			const `[pure virtual, inherited]`

All TinyXml classes can print themselves to a filestream or the string class (TiXmlString in non-STL mode, std::string in STL mode.

) Either or both cfile and str can be null.

This is a formatted print, and will insert tabs and newlines.

(For an unformatted stream, use the << operator.)

Implemented in TiXmlAttribute, TiXmlElement, TiXmlComment, TiXmlText, TiXmlDeclaration, TiXmlUnknown, and TiXmlDocument.

static const char* TiXmlBase::ReadName	(	const char *	p,
		TIXML_STRING *	name,
		TiXmlEncoding	encoding
	)			`[static, protected, inherited]`

static const char* TiXmlBase::ReadText	(	const char *	in,

Delete a child of this node.

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.

int TiXmlBase::Row ( ) const [inline, inherited]

Return the position, in the original source file, of this node or attribute.

The row and column are 1-based. (That is the first row and first column is 1,1). If the returns values are 0 or less, then the parser does not have a row and column value.

Generally, the row and column value will be set when the TiXmlDocument::Load(), TiXmlDocument::LoadFile(), or any TiXmlNode::Parse() is called. It will NOT be set when the DOM was created from operator>>.

The values reflect the initial load. Once the DOM is modified programmatically (by adding or changing nodes and attributes) the new values will NOT update to reflect changes in the document.

There is a minor performance cost to computing the row and column. Computation can be disabled if TiXmlDocument::SetTabSize() is called with 0 as the value.

See also:: TiXmlDocument::SetTabSize()

static void TiXmlBase::SetCondenseWhiteSpace ( bool condense ) [inline, static, inherited]

The world does not agree on whether white space should be kept or not.

In order to make everyone happy, these global, static functions are provided to set whether or not TinyXml will condense all white space into a single space or not. The default is to condense. Note changing this value is not thread safe.

void TiXmlBase::SetUserData ( void * user ) [inline, inherited]

Set a pointer to arbitrary user data.

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
