title: Parsing HTML via JMeter regexp
body: <p>I have some trouble with a regex in JMeter.
  I have this form in HTML</p>
  
  <pre><code>&lt;form class="UIForm" id="UIComposer" action="/portal/intranet/?portal:componentId=b5914710-6c12-4fa9-9a18-2707d97111b7&amp;interactionstate=JBPNS_rO0ABXcmAAt1aWNvbXBvbmVudAAAAAEAClVJQ29tcG9zZXIAB19fRU9GX18*&amp;portal:type=action" onsubmit="return false;" method="post"&gt;
  </code></pre>
  
  <p>and I need to get the values of <code>componentId</code> and <code>interactionstate</code> in JMeter, as variables.</p>
