title: In JMeter, how to capture values from REST POST Request (not the Response)?
body: <p>Part of REST POST Request looks like below where I am passing different values for VIN and DEALER_ID:</p>
  
  <pre><code>        &lt;ns3:PARAM&gt;
                &lt;ns3:ITEM&gt;VIN&lt;/ns3:ITEM&gt;
                &lt;ns3:VALUE xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string"&gt;${vin}&lt;/ns3:VALUE&gt;
          &lt;/ns3:PARAM&gt;
          &lt;ns3:PARAM&gt;
                &lt;ns3:ITEM&gt;DEALER_ID&lt;/ns3:ITEM&gt;
                &lt;ns3:VALUE xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string"&gt;${dealer_id}&lt;/ns3:VALUE&gt;
          &lt;/ns3:PARAM&gt;
  </code></pre>
  
  <p>I need to extract the values from ${vin} and ${dealer_id}, so I can have those on the CSV report with other values I am capturing from Response. I know how to capture values from Response, but don't know how to capture from variables in Request. Can someone help? Thanks. </p>
