Detailed Description

In correct XML the declaration is the first entry in the file. 

		<?xml version="1.0" standalone="yes"?>

TinyXml will happily read or write files without a declaration, however. There are 3 possible attributes to the declaration: version, encoding, and standalone.

Note: In this version of the code, the attributes are handled as special cases, not generic attributes, simply because there can only be at most 3 and they are always the same.

Member Enumeration Documentation

enum RTT::marsh::TiXmlNode::NodeType [inherited]

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

const TiXmlDocument * RTT::marsh::TiXmlNode::GetDocument ( ) const [inherited]

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 RTT::marsh::TiXmlNode::ToDocument().

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

TiXmlNode * RTT::marsh::TiXmlNode::InsertAfterChild ( TiXmlNode *  afterThis,
const TiXmlNode &  addThis 
) [inherited]

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 RTT::marsh::TiXmlNode::Clone().

TiXmlNode * RTT::marsh::TiXmlNode::InsertBeforeChild ( TiXmlNode *  beforeThis,
const TiXmlNode &  addThis 
) [inherited]

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 RTT::marsh::TiXmlNode::Clone().

TiXmlNode * RTT::marsh::TiXmlNode::InsertEndChild ( const TiXmlNode &  addThis) [inherited]

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 RTT::marsh::TiXmlNode::Clone(), and RTT::marsh::TiXmlNode::LinkEndChild().

const TiXmlNode * RTT::marsh::TiXmlNode::IterateChildren ( const TiXmlNode *  previous) const [inherited]

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 RTT::marsh::TiXmlNode::FirstChild(), and RTT::marsh::TiXmlNode::NextSibling().

TiXmlNode * RTT::marsh::TiXmlNode::LinkEndChild ( TiXmlNode *  addThis) [inherited]

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.

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

const TiXmlElement * RTT::marsh::TiXmlNode::NextSiblingElement ( ) const [inherited]

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 * RTT::marsh::TiXmlNode::NextSiblingElement ( const char *  _value) const [inherited]

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 RTT::marsh::TiXmlNode::NextSibling(), and RTT::marsh::TiXmlNode::ToElement().

TiXmlNode * RTT::marsh::TiXmlNode::ReplaceChild ( TiXmlNode *  replaceThis,
const TiXmlNode &  withThis 
) [inherited]

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 RTT::marsh::TiXmlNode::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, inherited]

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, inherited]

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, inherited]

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.
