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 Function Documentation

virtual bool omega::xml::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 omega::xml::TiXmlDocument, omega::xml::TiXmlUnknown, omega::xml::TiXmlDeclaration, omega::xml::TiXmlText, omega::xml::TiXmlComment, and omega::xml::TiXmlElement.

void omega::xml::TiXmlNode::Clear ( )

Delete all the children of this node. Does not affect 'this'.

virtual TiXmlNode* omega::xml::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 omega::xml::TiXmlDocument, omega::xml::TiXmlUnknown, omega::xml::TiXmlDeclaration, omega::xml::TiXmlText, omega::xml::TiXmlComment, and omega::xml::TiXmlElement.

void omega::xml::TiXmlNode::CopyTo ( TiXmlNode *  target) const
protected
const TiXmlNode* omega::xml::TiXmlNode::FirstChild ( ) const
inline

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

TiXmlNode* omega::xml::TiXmlNode::FirstChild ( )
inline
const TiXmlNode* omega::xml::TiXmlNode::FirstChild ( const char *  value) const

The first child of this node with the matching 'value'.

Will be null if none found.

TiXmlNode* omega::xml::TiXmlNode::FirstChild ( const char *  _value)
inline

The first child of this node with the matching 'value'. Will be null if none found.

const TiXmlElement* omega::xml::TiXmlNode::FirstChildElement ( ) const

Convenience function to get through elements.

TiXmlElement* omega::xml::TiXmlNode::FirstChildElement ( )
inline
const TiXmlElement* omega::xml::TiXmlNode::FirstChildElement ( const char *  _value) const

Convenience function to get through elements.

TiXmlElement* omega::xml::TiXmlNode::FirstChildElement ( const char *  _value)
inline
const TiXmlDocument* omega::xml::TiXmlNode::GetDocument ( ) const

Return a pointer to the Document this node lives in.

Returns null if not in a document.

TiXmlDocument* omega::xml::TiXmlNode::GetDocument ( )
inline
TiXmlNode* omega::xml::TiXmlNode::Identify ( const char *  start,
TiXmlEncoding  encoding 
)
protected
TiXmlNode* omega::xml::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* omega::xml::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* omega::xml::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* omega::xml::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* omega::xml::TiXmlNode::IterateChildren ( const TiXmlNode *  previous)
inline
const TiXmlNode* omega::xml::TiXmlNode::IterateChildren ( const char *  value,
const TiXmlNode *  previous 
) const

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

TiXmlNode* omega::xml::TiXmlNode::IterateChildren ( const char *  _value,
const TiXmlNode *  previous 
)
inline
const TiXmlNode* omega::xml::TiXmlNode::LastChild ( ) const
inline
TiXmlNode* omega::xml::TiXmlNode::LastChild ( )
inline

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

const TiXmlNode* omega::xml::TiXmlNode::LastChild ( const char *  value) const
TiXmlNode* omega::xml::TiXmlNode::LastChild ( const char *  _value)
inline

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

TiXmlNode* omega::xml::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.
