/**
****************************************************************************
* <P> XML.c - implementation file for basic XML parser written in ANSI C++
* for portability. It works by using recursion and a node tree for breaking
* down the elements of an XML document. </P>
*
* @version V2.41
* @author Frank Vanden Berghen
*
* NOTE:
*
* If you add "#define STRICT_PARSING", on the first line of this file
* the parser will see the following XML-stream:
* <a><b>some text</b><b>other text </a>
* as an error. Otherwise, this tring will be equivalent to:
* <a><b>some text</b><b>other text</b></a>
*
* NOTE:
*
* If you add "#define APPROXIMATE_PARSING" on the first line of this file
* the parser will see the following XML-stream:
* <data name="n1">
* <data name="n2">
* <data name="n3" />
* as equivalent to the following XML-stream:
* <data name="n1" />
* <data name="n2" />
* <data name="n3" />
* This can be useful for badly-formed XML-streams but prevent the use
* of the following XML-stream (problem is: tags at contiguous levels
* have the same names):
* <data name="n1">
* <data name="n2">
* <data name="n3" />
* </data>
* </data>
*
* NOTE:
*
* If you add "#define _XMLPARSER_NO_MESSAGEBOX_" on the first line of this file
* the "openFileHelper" function will always display error messages inside the
* console instead of inside a message-box-window. Message-box-windows are
* available on windows 9x/NT/2000/XP/Vista only.
