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.

Definition at line 425 of file tinyxml.h.

Member Enumeration Documentation

enum RTT::marsh::TiXmlNode::NodeType

The types of XML nodes supported by TinyXml.

(All the unsupported types are picked up by UNKNOWN.)

Definition at line 467 of file tinyxml.h.

Member Function Documentation

virtual TiXmlNode* RTT::marsh::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 RTT::marsh::TiXmlDocument, RTT::marsh::TiXmlUnknown, RTT::marsh::TiXmlDeclaration, RTT::marsh::TiXmlText, RTT::marsh::TiXmlComment, and RTT::marsh::TiXmlElement.

Referenced by InsertAfterChild(), InsertBeforeChild(), InsertEndChild(), and ReplaceChild().

const TiXmlDocument * RTT::marsh::TiXmlNode::GetDocument ( ) const

Return a pointer to the Document this node lives in.

Returns null if not in a document.

Definition at line 631 of file tinyxml.cpp.

References ToDocument().

Referenced by LinkEndChild(), and RTT::marsh::TiXmlElement::SetAttribute().

TiXmlNode * RTT::marsh::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.

Definition at line 289 of file tinyxml.cpp.

References Clone().

TiXmlNode * RTT::marsh::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.

Definition at line 263 of file tinyxml.cpp.

References Clone().

TiXmlNode * RTT::marsh::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.

Definition at line 253 of file tinyxml.cpp.

References Clone(), and LinkEndChild().

const TiXmlNode * RTT::marsh::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.

Definition at line 411 of file tinyxml.cpp.

References FirstChild(), and NextSibling().

TiXmlNode * RTT::marsh::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.

References GetDocument().

Referenced by InsertEndChild(), and RTT::marsh::TiXmlDocument::Parse().

const TiXmlElement * RTT::marsh::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.

Definition at line 574 of file tinyxml.cpp.

References NextSibling(), and ToElement().

Referenced by RTT::marsh::TiXmlHandle::ChildElement().

const TiXmlElement * RTT::marsh::TiXmlNode::NextSiblingElement ( const char *  _value) 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.

Definition at line 602 of file tinyxml.cpp.

References NextSibling(), and ToElement().

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

All TinyXml classes can print themselves to a filestream.

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

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

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

Referenced by RTT::marsh::TiXmlElement::Print(), and RTT::marsh::TiXmlDocument::Print().

TiXmlNode * RTT::marsh::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.

Definition at line 315 of file tinyxml.cpp.

References Clone().

int RTT::marsh::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()

Definition at line 235 of file tinyxml.h.

static void RTT::marsh::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 values is not thread safe.

Definition at line 212 of file tinyxml.h.

void RTT::marsh::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

Definition at line 511 of file tinyxml.h.

Referenced by RTT::marsh::TiXmlText::TiXmlText().

int RTT::marsh::TiXmlNode::Type ( ) const [inline]

Query the type (as an enumerated value, above) of this node.

The possible types are: DOCUMENT, ELEMENT, COMMENT, UNKNOWN, TEXT, and DECLARATION.

Definition at line 664 of file tinyxml.h.

const char* RTT::marsh::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.
