How can I extract variables from a SOAP response without namespace using Extract Variable policy.

SOAP response:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Body>
      <ServiceCatalogResponse xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
         <ServiceReply xsi:type="ns:ServiceReply" xmlns:ns="http://xmlns.telco.com/ServiceCatalog/ServiceReply" xmlns:ns0="http://schemas.xmlsoap.org/soap/envelope/">
            <ns:Header>
               <ns1:ResponseCode xmlns:ns1="http://xmlns.telco.com/EAI/Common/ResponseCodes">0</ns1:ResponseCode>
               <ns1:ResponseMsg xmlns:ns1="http://xmlns.telco.com/EAI/Common/ResponseCodes">Success</ns1:ResponseMsg>
               <ns1:ErrorDescription xmlns:ns1="http://xmlns.telco.com/EAI/Common/ResponseCodes"/>
               <ns1:RequestId xmlns:ns1="http://xmlns.telco.com/EAI/Common/ResponseCodes">41d17462666776</ns1:RequestId>
            </ns:Header>

Sample excerpt of Extract Variable policy:

 <Variable type="string" name="ResponseCode">
            <XPath>/SOAP-ENV:Envelope/SOAP-ENV:Body/xs:ServiceCatalogResponse/type:ServiceReply/ns:Header/ns1:ResponseCode/text()</XPath>
        </Variable>

My challenge is ServiceCatalogResponse and ServiceReply.How can I extract variable from the SOAP response and map it to the Extract Variable policy?

You shouldn’t include an alias for elements with no namespaces.

In your example,

/SOAP-ENV:Envelope/SOAP-ENV:Body/ServiceCatalogResponse/ServiceReply/ns:Header/ns1:ResponseCode/text()

should work.
