These are the ONLY 2 files that you + *need when using the library inside your own projects. + * + * All the functions of the library are documented inside the comments of the + *file <a href="../../xmlParser.h">xmlParser.h</a>. These comments can be + *transformed in full-fledged HTML documentation using the DOXYGEN software: + *simply type: "doxygen doxy.cfg" + * + * By default, the XMLParser library uses (char*) for string representation.To + *use the (wchar_t*) version of the library, you need to define the "_UNICODE" + *preprocessor definition variable (this is usually done inside your project + *definition file) (This is done automatically for you when using Visual + *Studio). + * + * \section example Advanced Tutorial and Many Examples of usage. + * + * Some very small introductory examples are described inside the Tutorial file + * <a href="../../xmlParser.html">xmlParser.html</a> + * + * Some additional small examples are also inside the file <a + *href="../../xmlTest.cpp">xmlTest.cpp</a> (for the "char*" version of the + *library) and inside the file <a + *href="../../xmlTestUnicode.cpp">xmlTestUnicode.cpp</a> (for the "wchar_t*" + * version of the library). If you have a question, please review these + *additionnal examples before sending an e-mail to the author. + * + * To build the examples: + * - linux/unix: type "make" + * - solaris: type "make -f makefile.solaris" + * - windows: Visual Studio: double-click on xmlParser.dsw + * (under Visual Studio .NET, the .dsp and .dsw files will be automatically + *converted to .vcproj and .sln files) + * + * In order to build the examples you need some additional files: + * - linux/unix: makefile + * - solaris: makefile.solaris + * - windows: Visual Studio: *.dsp, xmlParser.dsw and also xmlParser.lib and + *xmlParser.dll + * + * \section debugging Debugging with the XMLParser library + * + * \subsection debugwin Debugging under WINDOWS + * + * Inside Visual C++, the "debug versions" of the memory allocation + *functions are very slow: Do not forget to compile in "release mode" to get + *maximum speed. When I had to debug a software that was using the XMLParser + *Library, it was usually a nightmare because the library was sooOOOoooo slow in + *debug mode (because of the slow memory allocations in Debug mode). To solve + *this problem, during all the debugging session, I am now using a very fast DLL + *version of the XMLParser Library (the DLL is compiled in release mode). Using + *the DLL version of the XMLParser Library allows me to have lightening XML + *parsing speed even in debug! Other than that, the DLL version is useless: In + *the release version of my tool, I always use the normal, ".cpp"-based, + *XMLParser Library (I simply include the <a + *href="../../xmlParser.cpp">xmlParser.cpp</a> and <a + *href="../../xmlParser.h">xmlParser.h</a> files into the project). + * + * The file <a href="../../XMLNodeAutoexp.txt">XMLNodeAutoexp.txt</a> + *contains some "tweaks" that improve substancially the display of the content + *of the XMLNode objects inside the Visual Studio Debugger. Believe me, once you + *have seen inside the debugger the "smooth" display of the XMLNode objects, you + *cannot live without it anymore! + * + * \subsection debuglinux Debugging under LINUX/UNIX + * + * The speed of the debug version of the XMLParser library is tolerable so + *no extra work.has been done. + * + ****************************************************************************/ + +#ifndef __INCLUDE_XML_NODE__ +#define __INCLUDE_XML_NODE__ + +#include <stdlib.h> + +#ifdef _UNICODE +// If you comment the next "define" line then the library will never "switch to" +// _UNICODE (wchar_t*) mode (16/32 bits per characters).
