C++搜索引擎代码
求解这段代码什么意思？？
for(int i=1;i<=1;i++)
{
strUrl.Format("http://%s.58.com/xiaoqu/?page=%d",strPUrl,i);
strPageContent=GetDataFromHttp(strUrl);
strPageContent=(char*)ConvertUTF8toGB2312(strPageContent); //属于UTF-8编码
strPageContent.Replace(" ","");
strPageContent.Replace(" ","");
strPageContent.Replace(""","");
strPageContent.Replace(" ","");
//strHead="<tdclass=img><ahref=http://%s.58.com/xiaoqu/";
strHead.Format("href=http://%s.58.com/xiaoqu/",strPUrl);
// strTail="target=_blank";
strTail=">";
while(strPageContent.Find(strHead)!=-1)
{
strPageContent=strPageContent.Right(strPageContent.GetLength()-strPageContent.Find(strHead)-strHead.GetLength());
strId=strPageContent.Left(strPageContent.Find(strTail));
strPageContent=strPageContent.Right(strPageContent.GetLength()-strPageContent.Find(strTail)-strTail.GetLength());
/* if(strId.Find("\//")<=0) //不含有`两个//
{
continue;
} */
AfxMessageBox("text");
strSubUrl.Format("http://%s.58.com/xiaoqu/%sjieshao/",strPUrl,strId);
//strSubUrl.Format("http://%s.58.com/xiaoqu/%sjieshao/",strPUrl,strId);
strResult=GetDataFromHttp(strSubUrl);
strResult=(char*)ConvertUTF8toGB2312(strResult); //属于UTF-8编码
[解决办法]
循环代码，并且打开http://%s.58.com/xiaoqu/?page=%d这个网址，然后对其进行网页源代码进行分析，提取strHead和strTail之间的数据
