Grab content from webpage

For an application I am working on, I needed to integrate dynamic content from a webpage. Unfortunately the website doesn’t offer any kind of xml feed, so I needed to transform the xhtml from the webpage into a format for my application.

My first idea was to look at the xhtml as if it is xml, which could be a solution. Because I am convinced that there is always somebody else with the same problem or part of problem, I was searching the web for blog articles and forum posts for information about this.

While searching I found HtmlAgilityPack. HtmlAgilityPack is an open source library for the dotnet framework and makes it very easy to get html pages from an URL and search for content in that page. By using xpath, HtmlAgilityPack returns a Node or a Nodelist from which you can extract the inner text, inner html and all attributes. This is basically all you need to convert an (x)html page into something your application understands.

You can use it like this:

//Create the object and get the page
HtmlWeb hw = new HtmlWeb();
HtmlDocument doc = hw.Load(Url);

//Use Xpath to get a node
HtmlNodeExampleNode = doc.DocumentNode.SelectSingleNode("//div[@id='FinalResult']");

//Get the content from the node
string innerHtml = ExampleNode.InnerHtml;
string innerText = ExampleNode.InnerText;
string attribute = ExampleNode.Attributes["order"].Value;
