 TXMLParser                                                           
                                                                      
 TXMLParser is an abstract class which interfaces with Libxml2.       
 Libxml2 is the XML C parser and toolkit developed for the Gnome      
 project.                                                             
                                                                      
 The libxml library provides two interfaces to the parser, a DOM      
 style tree interface and a SAX style event based interface.          
                                                                      
 TXMLParser is parent class of TSAXParser, which is a SAX interface   
 of libxml.                                                           
                                                                      

 Cleanup.

 The parser will validate the xml file if val = true.

 To release any existing document.

 This function is called when an error from the parser has occured.
 Message is the parse error.

 This fucntion is called when a warning from the parser has occured.
 Message is the parse error.

 Returns the parse code message.

 Initialize parser parameters, such as, disactivate non-standards libxml1
 features, on/off validation, clear error and warning messages.

 Stops parsing.

 Set the parse code:
  0: Parse succesfull
 -1: Attempt to parse a second file while a parse is in progress
 -2: Parse context is not created
 -3: An error occured while parsing file
 -4: A fatal error occured while parsing file
 -5: Document is not well-formed

 Set parser stops in case of error:
 stop = true, stops on error
 stop = false, continue parsing on error...
