title: Get URL from HTML code using a regular expression
body: <p>Consider:</p>
  
  <pre><code>&lt;div&gt;&lt;a href="http://anirudhagupta.blogspot.com/"&gt;Anirudha Web blog&lt;/a&gt;&lt;/div&gt;
  </code></pre>
  
  <p>What is the regular expression to get <code>http://anirudhagupta.blogspot.com/</code>
  from the following?</p>
  
  <pre><code>&lt;div&gt;&lt;a href="http://anirudhagupta.blogspot.com/"&gt;Anirudha Web blog&lt;/a&gt;&lt;/div&gt;
  </code></pre>
  
  <p>If you suggest something in C# that's good. I also like jQuery to do this.</p>
