How could I get MIME type from a web view?

Question

I'm about to develop a browser plugin that detects whether a page is WML and if so, it will be transformed to HTML via an API.

What I want to do is override onPageFinished in WebViewClient and get MIME type from WebView. But there seems no such kind of methods in those two classes.

Am I missing anything or are there some other approaches? Any advice given will be appreciated.

You can try using MimeTypeMap's

getFileExtensionFromUrl() followed by getMimeTypeFromExtension()

Thanks, but that won't help if the URL just ends up with `php`, `aspx`, etc. I think I should check the DOM to see DOCTYPE is wml or the root of the XML is ``. – neuront Jul 29 '11 at 06:40
How about [guessContentTypeFromStream()](http://developer.android.com/reference/java/net/URLConnection.html#guessContentTypeFromStream(java.io.InputStream)) you can use [this](http://stackoverflow.com/questions/3134389/access-the-http-response-headers-in-a-webview/3134609#3134609) to get an InputStream – Reno Jul 29 '11 at 07:06
Thanks for the hint, and I have found a new approach. – neuront Jul 29 '11 at 12:27

I have just come up with an idea and seems work.

Load a javascript with loadUrl when the page is finish loading (onProgressChange to 100%). The js code is like

javascript:(function() {
    var wml_root = document.getElementsByTagName('wml');
    if (wml_root && wml_root.length > 0) {
        // apply an XLST or do something here...
    }
})()
