In your code you are querying for the payment element in default namespace  but in the XML response it is declared as in http   apilistener envoyservices com namespace   So  you are missing a namespace declaration    xml- gt registerXPathNamespace  envoy    http   apilistener envoyservices com      Now you can use the envoy namespace prefix in your xpath query   xpath    envoy payment     The full code would be    xml   simplexml load string  soap response    xml- gt registerXPathNamespace  envoy    http   apilistener envoyservices com    foreach   xml- gt xpath    envoy payment   as  item        print r  item       Note  I removed the soap namespace declaration as you do not seem to be using it  it is only useful if you would use the namespace prefix in you xpath queries

This is also quite nice if you subsequently need to resolve any objects into arrays   array   json decode json encode  responseXmlObject   true

One of the simplest ways to handle namespace prefixes is simply to strip them from the XML response before passing it through to simplexml such as below    your xml response     lt Your XML here gt     clean xml   str ireplace   SOAP-ENV     SOAP          your xml response    xml   simplexml load string  clean xml     This would return the following   SimpleXMLElement Object        Body    gt  SimpleXMLElement Object                        PaymentNotification    gt  SimpleXMLElement Object                                        payment    gt  SimpleXMLElement Object                                                        uniqueReference    gt  ESDEUR11039872                              epacsReference    gt  74348dc0-cbf0-df11-b725-001ec9e61285                              postingDate    gt  2010-11-15T15 19 45                              bankCurrency    gt  EUR                              bankAmount    gt  1 00                              appliedCurrency    gt  EUR                              appliedAmount    gt  1 00                              countryCode    gt  ES                              bankInformation    gt  Sean Wood                              merchantReference    gt  ESDEUR11039872

why don t u try using an absolute xPath     soap Envelope 1  soap Body 1  PaymentNotification 1  payment   or since u know that it is a payment and payment doesn t have any attributes just select directly from payment    soap Envelope 1  soap Body 1  PaymentNotification 1  payment
