Detailed Description

Any tag that TinyXML-2 doesn't recognize is saved as an unknown. It is a tag of text, but should not be modified. It will be written back to the XML, unchanged, when the file is saved.

DTD tags get thrown into XMLUnknowns.

Member Function Documentation

Accept()

virtual bool tinyxml2::XMLUnknown::Accept ( XMLVisitor *  visitor ) const

virtual

Accept a hierarchical visit of the nodes in the TinyXML-2 DOM. Every node in the XML tree will be conditionally visited and the host will be called back via the XMLVisitor interface.

This is essentially a SAX interface for TinyXML-2. (Note however it doesn't re-parse the XML for the callbacks, so the performance of TinyXML-2 is unchanged by using this interface versus any other.)

The interface has been based on ideas from:

• http://www.saxproject.org/
• http://c2.com/cgi/wiki?HierarchicalVisitorPattern

Which are both good references for "visiting".

An example of using Accept():

XMLPrinter printer;
tinyxmlDoc.Accept( &printer );
const char* xmlcstr = printer.CStr();

Implements tinyxml2::XMLNode.

operator=()

XMLUnknown& tinyxml2::XMLUnknown::operator= ( const XMLUnknown &  )

protected

ParseDeep()

char* tinyxml2::XMLUnknown::ParseDeep ( char *  , StrPair *  endTag  )

virtual

Reimplemented from tinyxml2::XMLNode.

ShallowClone()

virtual XMLNode* tinyxml2::XMLUnknown::ShallowClone ( XMLDocument *  document ) const

virtual

Make a copy of this node, but not its children. You may pass in a Document pointer that will be the owner of the new Node. If the 'document' is null, then the node returned will be allocated from the current Document. (this->GetDocument())

Note: if called on a XMLDocument, this will return null.

Implements tinyxml2::XMLNode.

ShallowEqual()

virtual bool tinyxml2::XMLUnknown::ShallowEqual ( const XMLNode *  compare ) const

virtual

Test if 2 nodes are the same, but don't test children. The 2 nodes do not need to be in the same Document.

Note: if called on a XMLDocument, this will return false.

Implements tinyxml2::XMLNode.

ToUnknown() [1/2]

virtual XMLUnknown* tinyxml2::XMLUnknown::ToUnknown ( )

virtual

Safely cast to an Unknown, or null.

Reimplemented from tinyxml2::XMLNode.

ToUnknown() [2/2]

virtual const XMLUnknown* tinyxml2::XMLUnknown::ToUnknown ( ) const

virtual

Reimplemented from tinyxml2::XMLNode.
