Using .NET's Webbrowser control for Windows Forms , it is pretty easy to access the DOM. Consider this scenario
this.webBrowser1.Navigate
(Path.Combine(Application.StartupPath,"TestPage.html"));
Now, Assume that you've a test javascript method in your html page, which accepts a string param. So, once loading is complete, you may
webBrowser1.Document.InvokeScript("test", new object[] { "hi" });
Now, I'm trying running this in Mono. At Runtime, Mono should be using Mono's web browser control - http://www.mono-project.com/WebBrowser. I am finding some very weird behavior (see the update)
Question is, how to access the HTML DOM, probably to invoke a script, via Mono's webbrowser control?
Update
Just noted that webBrowser1.Document is null only when I'm connected to the network. Otherwise, if I'm offline, the script is actually getting invoked, but then the Mono runtime crashes after that, with this error
