Odczytanie danych z XML Opcje

[maruder99]

Witam wszystkich.

Przyznaje, ze jestem raczej zielony w zagadnieniach XML. Moj problem polega na tym, ze chce wyciagnac konkretna wartosc z pliku XML i nie do konca jestem zadowolony z rezultatu.


To jest wzorzec odwolania do webservice:

CODE

POST /tracking.asmx HTTP/1.1
Host: adreswebservice.domena.com
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://www.domena.com/GetAffiliateGroupRevenueByUniqueId"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GetAffiliateGroupRevenueByUniqueId xmlns="http://domena.com/">
<strUniqueId>string</strUniqueId>
</GetAffiliateGroupRevenueByUniqueId>
</soap:Body>
</soap:Envelope>

To jest odpowiedz webservice:

CODE

HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GetAffiliateGroupRevenueByUniqueIdResponse xmlns="http://domena.com">
<GetAffiliateGroupRevenueByUniqueIdResult>
<intReturnCode>int</intReturnCode>
<strReturnMessage>string</strReturnMessage>
<intLeadId>int</intLeadId>
<strExpressConsent>string</strExpressConsent>
<strFindBrokerRequestGUID>string</strFindBrokerRequestGUID>
<dblLeadCost>double</dblLeadCost>
</GetAffiliateGroupRevenueByUniqueIdResult>
</GetAffiliateGroupRevenueByUniqueIdResponse>
</soap:Body>
</soap:Envelope>

A to kod, ktorym dysponuje na chwile obecna. Chcialbym jednak wyciagnac tylko wartosc leada
