2	****************************************************************************
3	* <P> XML.c - implementation file for basic XML parser written in ANSI C++
4	* for portability. It works by using recursion and a node tree for breaking
5	* down the elements of an XML document. </P>
6	*
7	* @version V2.33
8	* @author Frank Vanden Berghen
9	*
10	* NOTE:
11	*
12	* If you add "#define STRICT_PARSING", on the first line of this file
13	* the parser will see the following XML-stream:
14	* <a><b>some text</b><b>other text </a>
15	* as an error. Otherwise, this tring will be equivalent to:
16	* <a><b>some text</b><b>other text</b></a>
17	*
18	* NOTE:
19	*
20	* If you add "#define APPROXIMATE_PARSING" on the first line of this file
21	* the parser will see the following XML-stream:
22	* <data name="n1">
23	* <data name="n2">
24	* <data name="n3" />
25	* as equivalent to the following XML-stream:
26	* <data name="n1" />
27	* <data name="n2" />
28	* <data name="n3" />
29	* This can be useful for badly-formed XML-streams but prevent the use
30	* of the following XML-stream (problem is: tags at contiguous levels
31	* have the same names):
32	* <data name="n1">
33	* <data name="n2">
34	* <data name="n3" />
35	* </data>
36	* </data>
37	*
38	* NOTE:
39	*
40	* If you add "#define _XMLPARSER_NO_MESSAGEBOX_" on the first line of this file
41	* the "openFileHelper" function will always display error messages inside the
42	* console instead of inside a message-box-window. Message-box-windows are
43	* available on windows 9x/NT/2000/XP/Vista only.
