Hello!

Right now I'm working on a Internet Explorer add on which is supposed to scan a HTML-document for URL's in plain text, and then "linkify" them.

I have access to the websites DOM, and had an idea to traverse all of the DOM nodes and search for "links" using RegEx, to replace these text with HTML-code, however, when changing the "InnerText" property of the IHTMLElement object, all of it's child nodes are lost, which seriously destroys the website.

Here's some code, that nearly works, but only for nodes that doesn't have any children.

Can anyone please help me with this problem, I would be very grateful!

Regards

//This method is called when IE has finished loading a page
void _webBrowser2Events_DocumentComplete(object pDisp, ref object URL)
{
    if (pDisp == _webBrowser2)
    {
        HTMLDocument pageContent = _webBrowser2.Document;
        IHTMLElement bodyHtmlElmnt = pageContent.body;
        fixElement(bodyHtmlElmnt);
    }   
}
And here's the fixElement-method:

void fixElement(IHTMLElement node)
{
    if (node.innerText!=null && ((IHTMLElementCollection)node.children).length==0)
    {
        node.innerText= node.innerText.Replace("testString", "replaceWithThis");
    }

    foreach (IHTMLElement child in (node.children as mshtml.IHTMLElementCollection))
    {
        fixElement(child);
    }
}
