title: Fetching attribute value from property using ant - may be with propertyregex
body: <p>I tried using linecontainsregexp within filterchain ant-task by framing regexp pattern holding unique server name say 'act1' &amp; now property holds value like this:</p>
  
  <pre><code>&lt;Server name="act1" value="ServerName" port="1234"&gt;&lt;/Server&gt;
  </code></pre>
  
  <p>How to get individual attribute names?. For eg if I want to get port #, how to retrieve it. I tried with something like:</p>
  
  <pre><code>&lt;propertyregex property="extracted.prop" input="${server.details}"
                                 regexp="(.*)\\ *@@" select="\1" /&gt;
  </code></pre>
  
  <p>thank you.</p>
