title: How to add an anchor tag to a URL in a String
body: <p>I've got a few strings which contain youtube links (different lenghts and positions in the string, not every string contains an URL) and text. These strings will be written into paragraph-tags but i want the URLs to be clickable, so i need anchor tags around the URL.</p>
  
  <p>I managed to find a way to access the paragraph which contains a link:</p>
  
  <pre><code>if($("#facebookFeed p:contains('http')").length){
      //do stuff
  }
  </code></pre>
  
  <p>I'm stuck here and not sure if thats the right way to do it. </p>
