Oracle SOA 11G – lookupXRef1M function

lookupXRef() and lookupXRef1M() functions can be used to look up single and multiple values correspondingly from SOA 11G Cross Reference table (DEV_SOAINFRA.XREF_DATA).
lookupXRef1M() function will be used to look up multiple values of target system associated with the one value of source system.
Example Table Structure :

lookupXRef1M

Cross Reference Table ( DEV_SOAINFRA.XREF_DATA ) Structure :

XREF_DATA_TABLE

Issue:
lookupXRef1M() function looking up values differently for BPEL Assign activity and for BPEL Transformation (XSL).
While using with Assign activity it is giving the response like the below.
BPEL Assign activity :

<assign name="assignLookupXRef1M">            <copy>              <from expression="xref:lookupXRef1M('Sample.xref','SIEBEL','SBL_001','FUSION',true())"/>              <to variable="outputVariable" part="payload"                  query="/client:processResponse/client:result"/>            </copy>          </assign>

BPEL Assign activity response :

<outputVariable> <part  name="payload"> <processResponse>http://rathinasaba.wordpress.com/wp-admin/edit-comments.php <client:result> <value>FUS_001</value> <value>FUS_002</value> <value>FUS_003</value> </client:result> </processResponse> </part> </outputVariable>

While using it with XSL Transformation in BPEL it is just returning the concatenated values of target system.
BPEL Transformation:

<xsl:template match="/">     <client:processResponse>       <client:result>         <xsl:value-of select='xref:lookupXRef1M("Sample.xref",/client:process/client:xrefReferenceColumnName,/client:process/client:xrefReferenceColumnValue,/client:process/client:xrefColumnName,true())'/>       </client:result>     </client:processResponse>   </xsl:template>

BPEL Transformation response :

<outputVariable>     <part  name="payload">         <processResponse>             <client:result>FUS_001FUS_002FUS_003</client:result>         </processResponse>     </part> </outputVariable>

Solution to get the values properly in BPEL XSL Transformation :
Assign the lookupXRef1M() response in variable and iterate it using node() function like shown below with in the xsl to get the proper result as we get it in Assign activity.
