-****************************************************************************
-* <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 V2.43
-* @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.
