getting childnode in Response

Hi.. I have following code

import com.eviware.soapui.impl.wsdl.teststeps.*;
import com.eviware.soapui.support.XmlHolder;

def groovyUtils = new com.eviware.soapui.support.GroovyUtils( context );
def i=0;
def WsdlTestRequestName;

//Get the name of the WSDL test request

for( testStep in testRunner.testCase.getTestStepList() ) {
    if( testStep instanceof WsdlTestRequestStep ) {
    //log.info i++ +"Name of testcases in this suite: " +"[" +"]" +" Name of the WSDL step is " +testStep.getName();
    WsdlTestRequestName=testStep.getName();
    }
  }
// Get testresponse XML holder object
def responseHolder = groovyUtils.getXmlHolder("${WsdlTestRequestName}#Response");

//Declare the namespace - Hardcoded here. Dont know to get the namespace automatically.
//def names= responseHolder.getNamespaces()
//responseHolder.namespaces["imed"] = "http://blahblahbhala"

//Get all the Nodes of the selected Xpath
node = responseHolder.getDomNodes( "//imed:getMediaAssetResponse/getMediaAssetResponse/mediaAssetInfo/text/*" )

//Traverse each node
node.each {
 
   log.info "map node " + " - " + it.QName.toString() + ":" 
  }
// Cound number of nodes 
def nodeCount = responseHolder.getDomNodes("//imed:getMediaAssetResponse[1]/getMediaAssetResponse[1]/mediaAssetInfo[1]/document[1]/*").length

log.info nodeCount

to Parse following XML

            <copyrightOwner>sonoras imperio</copyrightOwner>
                  <deletedReason>quae divum incedo</deletedReason>
                  <approxDuration>100</approxDuration>
                   <originalRecordedDate>2009-05-16</originalRecordedDate>
                   <retentionReason>100</retentionReason>
                  <assetType>100</assetType>
                      <entityState>100</entityState>
                  <description>
                     <em3:Description>fremunt celsa</em3:Description>
                     <em3:Language>100</em3:Language>
                     <em3:Type>100</em3:Type>
                  </description>
                  <clip>
                     <id>100</id>
                        <sourceTimecodeIn>100</sourceTimecodeIn>
                     <sourceTimecodeOut>100</sourceTimecodeOut>
                       <sequenceTimecodeIn>100</sequenceTimecodeIn>
                     <sequenceTimecodeOut>100</sequenceTimecodeOut>
                     <sourceTimeCodeFormat>
                        <DropFrameIndicator>true</DropFrameIndicator>
                        <EditRate>100</EditRate>
                        <UnknownFormatIndicator>true</UnknownFormatIndicator>
                        <EditRateType>100</EditRateType>
                     </sourceTimeCodeFormat>
                  </clip>

However, I could not get the node names and values of inner XML trees like

   <description>
                     <em3:Description>fremunt celsa</em3:Description>
                     <em3:Language>100</em3:Language>
                     <em3:Type>100</em3:Type>
                  </description>

any help ?
