delphi 读取网页源代码问题

delphi 网页里有一个大表格，里面有各种数据。从源代码里知道这个表格的ID。如何用读源代码方法只读这个表格的源代码

获取网页源代码的最简单办法，就是利用 WinInet 单元中的函数：uses WinInet;function GetWebPage(const Url: string):string;var Session, Http文件:HINTERNET; szSizeBuffer:Pointer; dwLengthSizeBuffer:DWord; dwReserved:DWord; dwFileSize:DWord; dwBytesRead:DWord; Contents:PChar;begin Session:=InternetOpen('',0,niL,niL,0); Http文件:=InternetOpenUrl(Session,PChar(Url),niL,0,0,0); dwLengthSizeBuffer:=1024; HttpQueryInfo(HttpFile,5,szSizeBuffer,dwLengthSizeBuffer,dwReserved); GetMem(Contents,dwFileSize); InternetReadFile(HttpFile,Contents,dwFileSize,dwBytesRead); InternetCloseHandle(HttpFile); InternetCloseHandle(Session); Result:=StrPas(Contents); FreeMem(Contents);end;使用时，直接把收到的源代码显示出来：:Memo1.Text := GetWebPage(blog.asp?name=aliwy);
