Display XML in AxSHDocVw.AxWebBrowser

In my recent blog,  AxShDocVw, SHDocVw, mshtml References, I showed how to set up a VS.NET project to use the AxSHDocVw.AxWebBrowser control.

I was recently asked how to display formatted XML in this control. Here's just one way. I'm sure you can find ways to improve upon it.

private void DisplayXml(AxSHDocVw.AxWebBrowser browser,XmlDocument document)
{
   // generate a unique file name
     string filnam = Environment.GetFolderPath(Environment.SpecialFolder.InternetCache)
         + "\\" + document.GetHashCode().ToString();
    // clean up just incase
   if (File.Exists(filnam)) File.Delete(filnam);
    // write wsdl to a temporary file
   StreamWriter file = File.CreateText(filnam);
    string text = document.OuterXml.Replace("utf-16","utf-8");
   file.Write(text);
   file.Close();
   file = null;
    // navigate to the temporary file
   object refmissing = System.Reflection.Missing.Value;
   browser.Navigate(filnam, ref refmissing,ref refmissing, ref refmissing, ref refmissing);
}

This can be used when the control has not yet been initialized and does not yet have a body or DOM.
