I am trying to scrape the weather section from the following page http://www.zamnet.zm but am having trouble with my code - can anyone help out? <%@ Import Namespace="System.Net" %> <%@ Import Namespace="System.IO" %> <script language="C#" runat="server"> void Page_Load(Object Src, EventArgs E) { myPage.Text = readHtmlPage("http://www.zamnet.zm"); myWeather.Text = GetWeather(myPage.Text, "Lusaka Today","View Other Zambian Cities"); } private String readHtmlPage(string url) { String result; WebResponse objResponse; WebRequest objRequest = System.Net.HttpWebRequest.Create(url); objResponse = objRequest.GetResponse(); using (StreamReader sr = new StreamReader(objResponse.GetResponseStream()) ) { result = sr.ReadToEnd(); // Close and clean up the StreamReader sr.Close(); } return result; } private static string GetWeather(string Content, string beginSection, string endSection) { int iFoundBegin = Content.IndexOf(beginSection); if (iFoundBegin != -1) { int iFoundEnd = Content.IndexOf(endSection,iFoundBegin + beginSection.Length); if (iFoundEnd != -1) { return Content.Substring(iFoundBegin + beginSection.Length, iFoundEnd - (iFoundBegin + beginSection.Length)); } } return null; } </script> <html> <body> This content is being populated from a separate HTTP request to <a href=http://aspmessageboard.com/archive/index.php/"http://www.zamnet.zm">http://www.zamnet.zm</a>:<hr/> <asp:literal id="myPage" runat="server"/> <asp:literal id="myWeather" runat="server"/> </body> </html>
