from input xml. My scenario im getting xml like this....

<?xml version="1.0" encoding="UTF-8"?>
<XSDPaymentRequestMsg xmlns="urn:XSD:xsd:XSDPaymentRequestMsg.00.03.00"
xmlns:HE2E="urn:XSD:xsd:XSDHdrSrv.001.07"
xmlns:HTRT="urn:XSD:xsd:XSDHdrTrt.001.07"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<XSDBdyPaymentRequest
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:SSRD="urn:XSD:xsd:XSDBdyPaymentRequest.00.03.00"
xmlns:SGNT="urn:XSD:xsd:XSDSgnInf.001.04"
xmlns:GPRS="urn:XSD:xsd:XSDPaymentRequest.00.03.00">
<SSRD:XSDEnvelPaymentRequest>
<SSRD:XSDPaymentRequest>
<GPRS:GrpHdr>
<GPRS:MsgId>2008013100010</GPRS:MsgId>
<GPRS:CreDtTm>2008-01-31T15:14:53</GPRS:CreDtTm>
<GPRS:NbOfTxs>2</GPRS:NbOfTxs>
<GPRS:CtrlSum>27.00</GPRS:CtrlSum>
<GPRS:Grpg>GRPD</GPRS:Grpg>
<GPRS:InitgPty>
<GPRS:Nm>Fortunati Maria Grazia</GPRS:Nm>
<GPRS:Id>
<GPRS:OrgId>
<GPRS:TaxIdNb>
FRTMGR70D60G337W
</GPRS:TaxIdNb>
<GPRS:PrtryId>
<GPRS:Id>0031885X</GPRS:Id>
<GPRS:Issr>ACBI</GPRS:Issr>
</GPRS:PrtryId>
</GPRS:OrgId>
</GPRS:Id>
</GPRS:InitgPty>
</GPRS:GrpHdr>
</SSRD:XSDPaymentRequest>
</SSRD:XSDEnvelPaymentRequest>
</XSDBdyPaymentRequest>
</XSDPaymentRequestMsg>

if i get object like this...

final XSDPaymentRequestMsgDocument requestMsgDocument =
XSDPaymentRequestMsgDocument.Factory.parse(inputXml,new XmlOptions().setSaveAggresiveNamespaces());
XSDBdyPaymentRequest000305 request000305 =
requestMsgDocument.getXSDPaymentRequestMsg().getXSDBdyPaymentRequest();
XSDPaymentRequest000305 request0003052 =
request000305.getXSDEnvelPaymentRequestArray(0).getXSDPaymentRequest();

XSDGenericIdentification1 pmtrequest = request0003052.getGrpHdr().getInitgPty().getId().getOrgId().getPrtryId();

System.out.println(">>> pmtrequest = "+pmtrequest );

OUTPUT

I will get like this.....

<xml-fragment
xmlns:urn="urn:XSD:xsd:XSDPaymentRequest.00.03.05"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:HTRT="urn:XSD:xsd:XSDHdrTrt.001.07"
xmlns:HE2E="urn:XSD:xsd:XSDHdrSrv.001.07\"
xmlns:BODY="urn:XSD:xsd:XSDBdyPaymentRequest.00.03.05">
<GPRS:Id>0031885X</GPRS:Id>
<GPRS:Issr>ACBI</GPRS:Issr>
</xml-fragment>
