webservices parsing problem

guys can you give suggestions on how to parse the RESULTS of this soap request?

soap_request("StepName=XXYYZZ",          
  "URL=*************",          
  "SOAPEnvelope="
  "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:iden=\"&&&&&&&&&&&&&\" xmlns:$$$$$$$$$$$$$\">"
     "<soapenv:Header>"
      "</soapenv:Header>"
     "<soapenv:Body>"
        "<abc:ENROLL>"
           "<userDetails>"
              "<firstName>{fName}</firstName>"
              "<lastName>{Lname}</lastName>"
              "<birthDate>{Bday}</birthDate>"
              "<phoneNumber>"
                 "<areaCode>091</areaCode>"
                 "<mainPhoneNumber>{phone_num}</mainPhoneNumber>"
              "</phoneNumber>"
              "<emailAddress>{eMail}</emailAddress>"
           "</userDetails>"
           "<rxNum>{Presc_num}</rxNum>"
           "<schoolId>55555</schoolId>"
        "</abc:ENROLL>"
     "</soapenv:Body>"
  "</soapenv:Envelope>",          
  "SOAPAction=XXYYZZ", 
  "ResponseParam=Results", 
    LAST);
