Below is the code i use to alter the HTML displayed in IE. However it always throws exception - Could not set the outerHTML property. Invalid target element for this operation. Ain't it possible to set the outerHTML?

protected void AlterContent(ref HTMLDocument docInput, HTMLDocument docAlteredOutPut)
{
    try
    {
        if (docInput开发者_StackOverflow.body.tagName.ToLower() == "body" && docAlteredOutPut.body.innerHTML != null)
        {
            docInput.documentElement.outerHTML = docAlteredOutPut.documentElement.outerHTML;
        }
    }
    catch
    {
    }
}

Thanks.

You cannot replace the html for the<body>element. There's no need to, this works fine:

public partial class Form1 : Form {
    public Form1() {
        InitializeComponent();
        webBrowser1.Url = new Uri("http://stackoverflow.com");
        webBrowser1.DocumentCompleted += webBrowser1_DocumentCompleted;
    }
    void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) {
        var body = webBrowser1.Document.Body;
        body.InnerHtml = "pwned";
    }
}
