纯C实现xml构造解析器，所有实现只有一个.c一个.h文件组成，简单易用，易于扩展。

#include <string.h>
#include <stdio.h>
#include <stdlib.h>
#include "sxml.h"
#define LUA_SCRIPT "function fun()\n\
  int a;\n\
  a = 10;\n\
  return a;\n\
end"
int main()
{

  char* tmp;
  const char* pstr;
  int line=1;

  sxml_doc_t* parser=NULL;
  sxml_doc_t* doc = sxml_doc_new("a.xml","1.0","GB2312");
  sxml_node_t* node = sxml_node_new("root");

  printf("%s\n", tmp);
  while((pstr = skip_line(pstr)))line++;

  //tmp = sxml_doc_print(parser);//有问题，内存越界
  tmp = sxml_doc_print_buffered(parser,16);
  printf("%s\n", tmp);

}
