Hi All

I need help with below Response analysis.I get this response from IBM webmethods and in C# i am able to read all nodes trhough the proxy class except the <batch> node which is showing as Null. Is it because of the xsi:nil="true"?
why is it not reading the batch attributes and returning me the receivedate,writeoffs,payments etc


-<soapenv:envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
-<soapenv:body>
-<ser-root:processlockboxboatoamdresponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ser-root="http://">
-<newbatchresponse encoding="ISO-8859-1" version="1.0">
-<ppmdresults n="1" lst="7/12/2016 10:55:02 AM" s="CB-API04">
-<results>
-<batchlist>
<b> <batch xsi:nil="true" receivedate="07/12/2016" writeoffs="0.00" payments="0.00" charges="0.00" owner="MED-FUL" closeddate="" servicedate="" postingdate="07/12/2016" status="a" number="171" id="bat124112" /></b>
</batchlist>
</results>
<error xsi:nil="true" />
</ppmdresults>
</newbatchresponse>
</ser-root:processlockboxboatoamdresponse>
</soapenv:body>
</soapenv:envelope>

What I have tried:

I was trying to just read the response from proxy object and didnt get any error. I was wondering when other elements return value why is <batch> not returning and ran fiddler and got this response.
