title: regular expression to find meta value
body: <p>i am trying to read from a webpage and get the last modified date from meta. for example</p>
  
  <pre><code>&lt;head&gt;
  &lt;meta http-equiv="Content-Type" content="text/html; charset=windows-1252"&gt;
  &lt;meta http-equiv="last-modified" content="Mon, 17 Sep 2012 13:57:35 SGT" /&gt;
  &lt;/head&gt;
  </code></pre>
  
  <p>i am reading line by line, how can i build the regex in this case? I am fairly new to the regex. i have tried</p>
  
  <pre><code>line.matches("&lt;meta http-equiv=\"last-modified\" content=\"(\w)*\" /&gt; "); 
  </code></pre>
  
  <p>but do not think it is correct.</p>
