BIRT Reporting: Web Service Data Source doesn't return data

[crampz]

I'm trying to retrieve data from a webservice using the BIRT data source. The data that the server gives me as response looks something like this:\[code\]<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:kpi="http_adress"> <soap:Header/> <soap:Body> <kpi:someMethod> <!--Optional:--> <SomeList> <!--Zero or more repetitions:--> <SomeVariable oid="R2D2" versionNr="1.0"> <!--Optional:--> <Variable1>10</Variable1> <!--Optional:--> <Variable2>Value</Variable2> </SomeVariable > </SomeList> </kpi:someMethod> </soap:Body></soap:Envelope>\[/code\]My problem is that the data sets in BIRT only go 3 levels deep. It basically tells me to select the line as a data row. How do I get those Variable1 and Variable2 in the Data Set?
