I have an HTML document with an iFrame, which i am loading in a webbrowser window. My objective is once that iFrame document is loaded, capture the document contents and search for a particular line.
I am not been able to do it so far, any suggestions ?
HTML CODE
<html>
<body>
<iframe id="monitor" src="http://monitor.baseline.com"></iframe>
</body>
</html>
On
i got it by doing the below
var javascript = @"
var Frame = document.getElementById('monitor');
window.external.iFrameCheck(Frame.contentWindow.document);
";
var doc = (IHTMLDocument2)webBrowser1.Document;
//Once we have the document, execute our JavaScript in it
doc.parentWindow.execScript(javascript);
this would then call the below c# code
[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
[ComVisible(true)]
public class ComVisibleObjectForScripting
{
public void iFrameCheck(HTMLDocument FrameDoc)
{
//Do what you want here with your FrameDoc
// the innerHTML will give you the content of the iframe
}
}
You can add a JavaScript function to the OnLoad event of the iFrame:
And then follow these solutions to parse your document. But be aware about cross-site-scripting restrictions. If the src of your iFrame is a totally different domain, it probably won't work.
