Execute scripts to interact with the web document:

Dim source = Await WebView21.ExecuteScriptAsync("document.documentElement.outerHTML")
Dim decoded = System.Text.RegularExpressions.Regex.Unescape(source)

Hi John, thanks for your help.

I tried but "on the first line "Await" gives the following error:

BC37058: 'Await' can only be used within an Async method. Consider marking this method with the 'Async' modifier and changing its return type to Tasks.

Any suggestions

Thanks once again.

Yes, you must add Async to your method. If it's an event handler Sub-method you don't add return type.
