1. 测试tinyxml库
  1. cong@msi:/work/cloud/test$ tree xml/
  2. xml/
  3. ├── a.xml                  -->测试用的xml
  4. ├── Makefile               -->Makefile
  5. ├── test.cpp               -->测试用demo
  6. ├── tinystr.cpp            -->下面这几个都是从tinyxml中扣出来的
  7. ├── tinystr.h
  8. ├── tinyxml.cpp
  9. ├── tinyxmlerror.cpp
  10. ├── tinyxml.h
  11. └── tinyxmlparser.cpp

  13. 0 directories, 9 files

2. 代码如下
  1. cong@msi:/work/cloud/test/xml$ cat test.cpp
  2. #include <stdio.h>
  3. #include <stdlib.h>
  4. #include <string.h>
  5. #include <errno.h>
  6. #include <iostream>
  7. #include <string>

  9. #include "tinyxml.h"

  11. #define dbmsg(fmt, args ...) printf("%s:%s[%d]: "fmt"\n", __FILE__,__FUNCTION__, __LINE__,##args)
