title: Regex for matching url prefix
body: <p>I want to delete the Google prefix in all URLs.</p>
  
  <pre><code>&lt;a href="http://news.google.com/news/url?sa=t&amp;fd=R&amp;ct2=en&amp;usg=YFo&amp;url=http://www.goo.tv/gd/2015/0509/735557.html

  </code></pre>
  
  <p>I want to remove <code>http://news.google.com/news/url?sa=t&amp;fd=R&amp;ct2=en&amp;blalba....url=</code>
  this Google prefix, so that it only retains the real URL.</p>
  
  <p>I tried the regex, but it doesn't match each prefix, it matches all content 
  <code>&lt;a href="(http:\/\/news.google.com/news/url\?([\s\S]*)&amp;url=)</code></p>
