c语言截取字符串中的某段字符串

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

int  main(void)

{

      char srcBuf[1024] = {0};

      int srcLen = 0;

      char* bufTmp = NULL;

      char destBuf[128] = {0};

     snprintf(srcBuf,1024,”<?xml version=\”1.0\”?>\r\n”

                                  “<Response>\r\n”

                                  “<Type>A</Type>\r\n”

                                  “</Response>\r\n”);

    srcLen = strlen(srcBuf);//”转义字符\不算入长度”

    bufTmp = strstr(srcBuf,”<Response>”);

    strncat(destBuf,srcBuf,bufTmp-srcBuf);

    printf(“destBuf:%s\n”,destBuf);

    return 0;

}

输出结果：<?xml version=”1.0″?>
