soapui - SOAP 応答の CDATA からの JSON コンテンツの抽出

Question

I am working on SoapUI where I have a Soap request which takes input in Json String format and after the processing I get a Soap Response in XML with JSON format enclosed in CDATA.

I am trying to extract the data from Soap Response using the below code but I get error "Content is not allowed in prolog"

import com.eviware.soapui.support.XmlHolder
import net.sf.json.groovy.JsonSlurper
import groovy.xml.Namespace

respXmlHolder = new XmlHolder(messageExchange.getResponseContentAsXml())
respXmlHolder.declareNamespace("ns1","http://tempuri.org/")
CDATAXml = respXmlHolder.getNodeValue("//ns1:ReportResult")
log.info(CDATAXml)


def data = new XmlParser().parseText(CDATAXml).Rpt
log info "data.findAll{it.'Name'}.size()"

The Soap Response looks this way as shown below:

<ReportResponse xmlns="http://tempuri.org/">
     <ReportResult><![CDATA[{
  "Report": [
    {
      "Name": "ABC",
      "Number": "123",
      "Type": "XYZ",
      "Desc": "EFGH",
      "Group Name": "Name123",
      "Group Number": "123",
      "End Date": "12/30/2014",
      "Due Date": "04/15/2015",
      "Completion Date": null,
      "Status": "Status1",
      "Received Date": "",
      "Delivery Date": "",
      "Location": "",
      "Role": "",
     },
     {
      "Name": "EFG",
       "Number": "123",
      "Type": "XYZ",
      "Desc": "EFGH",
      "Group Name": "Name123",
      "Group Number": "123",
      "End Date": "12/30/2014",
      "Due Date": "04/15/2015",
      "Completion Date": null,
      "Status": "Status1",
      "Received Date": "",
      "Delivery Date": "",
      "Location": "",
      "Role": "Manager",
     }
    ]
} ]]></ReportResult>
  </ReportResponse>
   </s:Body>
</s:Envelope>

Please help me in this regard.
