title: How to handle special characters (such as "&") in Convert Query Params to XML of datapower
body: <p>I am new to datapower, so I am sorry its silly question.</p>
  
  <p>I have create one flow in datapower whose request and response type is Non-XML.
  when I try to post an XML to my flow I am getting following error.</p>
  
  <p><code>Convert HTTP produced invalid XML: mismatched tag, expected employed_by at offset</code> </p>
  
  <p>here is the sample request XML :-</p>
  
  <pre><code>...
  &lt;emp_status type="employed" /&gt;
  &lt;employed_by&gt;abc &amp;amp; company&lt;/employed_by&gt;
  &lt;work_phone_no&gt;XXXXX&lt;/work_phone_no&gt;
  &lt;years_employed&gt;10&lt;/years_employed&gt;
  &lt;months_employed&gt;10&lt;/months_employed&gt; 
  ...
  </code></pre>
  
  <p>but If I remove <code>&amp;amp;</code> from the request XML then my flow works fine.</p>
