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 have to debug a software that is 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 use 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). -// This is useful when you get error messages like: -// 'XMLNode::openFileHelper' : cannot convert parameter 2 from 'const char [5]' to 'const wchar_t *' -// The _XMLWIDECHAR preprocessor variable force the XMLParser library into either utf16/32-mode (the proprocessor variable -// must be defined) or utf8-mode(the pre-processor variable must be undefined). -#define _XMLWIDECHAR -#endif - -#if defined(WIN32) || defined(UNDER_CE) || defined(_WIN32) || defined(WIN64) || defined(__BORLANDC__) -// comment the next line if you are under windows and the compiler is not Microsoft Visual Studio (6.0 or .NET) or Borland -#define _XMLWINDOWS -#endif - -#ifdef XMLDLLENTRY -#undef XMLDLLENTRY -#endif -#ifdef _USE_XMLPARSER_DLL -#ifdef _DLL_EXPORTS_ -#define XMLDLLENTRY __declspec(dllexport) -#else -#define XMLDLLENTRY __declspec(dllimport) -#endif -#else -#define XMLDLLENTRY -#endif - -// uncomment the next line if you want no support for wchar_t* (no need for the <wchar.h> or <tchar.h> libraries anymore to compile) -//#define XML_NO_WIDE_CHAR - -#ifdef XML_NO_WIDE_CHAR -#undef _XMLWINDOWS -#undef _XMLWIDECHAR -#endif - -#ifdef _XMLWINDOWS -#include <tchar.h> -#else -#define XMLDLLENTRY -#ifndef XML_NO_WIDE_CHAR -#include <wchar.h> // to have 'wcsrtombs' for ANSI version - // to have 'mbsrtowcs' for WIDECHAR version -#endif -#endif - -// Some common types for char set portable code -#ifdef _XMLWIDECHAR - #define _CXML(c) L ## c - #define XMLCSTR const wchar_t * - #define XMLSTR wchar_t * - #define XMLCHAR wchar_t -#else - #define _CXML(c) c - #define XMLCSTR const char * - #define XMLSTR char * - #define XMLCHAR char -#endif -#ifndef FALSE - #define FALSE 0 -#endif /* FALSE */ -#ifndef TRUE - #define TRUE 1 -#endif /* TRUE */ - - -/// Enumeration for XML parse errors. -typedef enum XMLError -{ - eXMLErrorNone = 0, - eXMLErrorMissingEndTag, - eXMLErrorNoXMLTagFound, - eXMLErrorEmpty, - eXMLErrorMissingTagName, - eXMLErrorMissingEndTagName, - eXMLErrorUnmatchedEndTag, - eXMLErrorUnmatchedEndClearTag, - eXMLErrorUnexpectedToken, - eXMLErrorNoElements, - eXMLErrorFileNotFound, - eXMLErrorFirstTagNotFound, - eXMLErrorUnknownCharacterEntity, - eXMLErrorCharacterCodeAbove255, - eXMLErrorCharConversionError, - eXMLErrorCannotOpenWriteFile, - eXMLErrorCannotWriteFile, - - eXMLErrorBase64DataSizeIsNotMultipleOf4, - eXMLErrorBase64DecodeIllegalCharacter, - eXMLErrorBase64DecodeTruncatedData, - eXMLErrorBase64DecodeBufferTooSmall -} XMLError; - - -/// Enumeration used to manage type of data.
