This example shows how to use the Chilkat HTTP component to fetch the CNN home page, convert it to XML, and then use Chilkat XML to navigate to the main headline and extract it. This example worked on 6-June-2005. Future changes in the HTML delivered by CNN may break this code, but the purpose of the code is to demonstrate the ease of extracting information from HTML.

// Create an instance of Chlkat.Http to fetch the CNN home page.
Chilkat.Http http = new Chilkat.Http();
http.UnlockComponent("HTTP 30-day trial");

// Make our HTTP client mimic Mozilla Firefox
http.MimicFireFox = true;

// Do not fetch from cache or save to cache.
http.FetchFromCache = false;
http.UpdateCache = false;
		
Chilkat.HtmlToXml conv = new Chilkat.HtmlToXml();
conv.UnlockComponent("Html-to-Xml 30-day trial");

// Get the HTML for the CNN home page.		    
conv.Html = http.QuickGetStr("http://www.cnn.com/");

// Convert it to XML and load it into Chilkat XML.
Chilkat.Xml xml = new Chilkat.Xml();
xml.LoadXml(conv.ToXml());

// Navigate to the main headline.
// This works based on the structure of the CNN home page on 6-June-2005.
// This code can break if the HTML returned by CNN changes in certain ways.
// The purpose of this example is to show how easy it is to extract a piece
// of information from an HTML page.
Chilkat.Xml node = xml.SearchForAttribute(null,"div","class","cnnMainT1Hd");
if (node != null) 
{
    node.FirstChild2();
    node.FirstChild2();
    node.FirstChild2();
    MessageBox.Show("Main Headline = " + node.Content);
}
