Dear Experts,

I want to get the informatin from a remote website. I am using MFC classes for getting the information. It is working fine. I am able to get the whole html file but what i want is only text content in the webpage. I am using the following code.

CInternetSession *strSess = new CInternetSession("new");
CString pServer;
CString pObject;
CString strUrl = "";
CHttpConnection* httpcon = strSess->GetHttpConnection(pServer,nport);
CHttpFile * httpFile = httpcon->OpenRequest(1,pObject,NULL,1,NULL,NULL,INTERNET_FLAG_EXISTING_CONNECT);
          BOOL result = httpFile->SendRequest(NULL,0,NULL,0);
          CStdioFile str("c:\\test.txt",CFile::modeCreate | CFile::modeReadWrite);


catch(CInternetException * thro)
          TCHAR strError[255];
          cout<<"There was some error";

how to do this.

>>whole html file but what i want is only text content in the webpage

Can you be more specific?  The "text content" and the "html file" for a web page are the SAME THING.

You mean you want the markup tags removed (and all comment, script and style elements)?
Then you'd parse the file and remove anything that's not between <body> and </body>.
In the body element, remove the markuptags, basically anything between angled braces '<' and '>'
This also takes care of the comments and most script and style declarations since most html designers place those within a comments.
Finally, replace &xxx; codes (like &nbsp; &lt;) with their proper characters.

No, there are no MFC classes or functions to parse the HTML.  For this you need an HTML parser.  See:

for information and software to do this.

What you are trying to do is NON-TRIVIAL!

There is a sample on how to use Microsoft's MSHTML as an HTML parser.  You must have IE 4.0 or later
