Equivalent method of WebBrowser.DocumentText in WebView2

Question

The question is not new, however none of the tons of answers I tried worked for me. Here is what I used to do before in IE WebBrowser object:

int_start_tag = myWebBrowser.DocumentText.IndexOf("radius:\">");

Looks simple enough. I can't figure out how to do the same thing using WebView2. The commented lines are tests and don't work for me. MessageBox.Show is just for me to verify the contents, but I would be doing some processing on the return data.

        private async void button3_Click(object sender, EventArgs e)
        {
            //String html = await webView21.ExecuteScriptAsync("document.documentElement.outerHTML");
            String html = await webView21.CoreWebView2.ExecuteScriptAsync("document.body.outerHTML");
            //String htmldecoded = System.Web.Helpers.Json.Decode(html);
            MessageBox.Show(html);
        }

Answer 1

This works for me :

                string sHtml = await webView21.CoreWebView2.ExecuteScriptAsync("document.documentElement.outerHTML");
                string sHtmlDecoded = System.Text.RegularExpressions.Regex.Unescape(sHtml);
                Debug.WriteLine(sHtmlDecoded);
