title: Find a Text / String in a WebView of windows phone 8.1
body: <p>I have a local html file opened in the WebView, here I need to search a Text from the webview. Android has  <code>webview.findAll(string);</code> &amp; <code>webview.findAllAsync(string);</code> methods to achieve this.</p>
  
  <p>Is there any method or alternative to do the same in windows phone 8.1??</p>
