body: <p>I've an xml payload that returns to me</p>
  
  <pre><code>&lt;response&gt;&lt;row&gt;&lt;row _id="1" _uuid="CD07C40E-4943-44B0-BF5E-370DA2133E25" _position="1"

   _address="http://data.seattle.gov/resource/fire-911/111"&gt;&lt;address&gt;10049 College Way N&lt;/address&gt; 
   &lt;type&gt;Aid Response&lt;/type&gt;&lt;latitude&gt;47.701756&lt;/latitude&gt;&lt;longitude&gt;-122.335022&lt;/longitude&gt;
   &lt;report_location latitude="47.701756" longitude="-122.335022"/&gt;
   &lt;incident_number&gt;F110104009&lt;/incident_number&gt;&lt;/row&gt;

  <p>I want to capture the "row" nodes with xpath : <code>#[xpath://response/row/row]</code>. This returns me a string of commas <code>[, , , , , , , ,]</code> instead of </p>
  
  <pre><code>&lt;row _id="111" _uuid="2423EC44-56D5-494C-941F-6F3B5DF49AC5" _position="111" _address="http://data.seattle.gov/resource/fire-911/111"&gt;
      &lt;address&gt;10049 College Way N&lt;/address&gt; 
      &lt;type&gt;Aid Response&lt;/type&gt;
      &lt;latitude&gt;47.701756&lt;/latitude&gt;
      &lt;longitude&gt;-122.335022&lt;/longitude&gt;
      &lt;report_location latitude="47.701756" longitude="-122.335022"/&gt;
      &lt;incident_number&gt;F110104009&lt;/incident_number&gt;
  &lt;/row&gt;      
  </code></pre>
  
  <p>If I insert this xpath through an online tester, this works: <code>//response/row/row</code></p>
  
  <pre><code>&lt;row _id="112" _uuid="DDAE5717-4A07-4E71-9CAE-D1F1CBAA94FD" _position="112"  _address="http://data.seattle.gov/resource/fire-911/112"&gt;
      &lt;address&gt;5929 Beach Dr Sw&lt;/address&gt;  
      &lt;type&gt;Aid Response&lt;/type&gt;
      &lt;latitude&gt;47.550431&lt;/latitude&gt;
      &lt;longitude&gt;-122.397816&lt;/longitude&gt; 
      &lt;report_location latitude="47.550431" longitude="-122.397816"/&gt;
      &lt;incident_number&gt;F110104008&lt;/incident_number&gt;
  &lt;/row&gt;
  </code></pre>
  
  <p>What would I have to do get it to work in mule? </p>
  
  <p>My configuration.xml:</p>
  
  <pre><code>    &lt;flow name="seattleemergencyFlow1" doc:name="seattleemergencyFlow1"&gt;
      &lt;http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8900"   
      path="get-emergency" doc:name="HTTP"/&gt;
      &lt;http:outbound-endpoint exchange-pattern="request-response" host="data.seattle.gov" port="80" 
       path="resource/kzjm-xkqj.xml?" method="GET" contentType="application/json" doc:name="HTTP"/&gt;
      &lt;object-to-string-transformer doc:name="Object to String"/&gt;
      &lt;logger message="#[xpath://response/row/row]" level="ERROR" doc:name="Logger"/&gt;
  </code></pre>
  
  <p>Thank you!</p>
