Calling ora:processXQuery from bpel with parameters

Question

I am trying to call ora:processXQuery from bpel with parameters. I am using SOA Suite 11.1.1.7
ora:processXQuery('selectVersionNumber.xq',bpws:getVariableData('XML_FILE_VAR','/ns4:InputParameters'),"OBJ_ID_VAR","OBJ_ID_INNER_VAR", bpws:getVariableData('OBJ_ID_VAR'),bpws:getVariableData('OBJ_ID_INNER_VAR'))
selectVersionNumber.xq :
xquery version "1.0";
declare namespace ns4="http://www.example.org";
let $item := //ns4:P_RELATIONSHIP_TBL
for $x in $item/P_RELATIONSHIP_TBL_ITEM
    for $y in $x/ns4:P_RELATIONSHIP_TBL_INNER/ns4:P_RELATIONSHIP_TBL_ITEM_INNER
    where $x/ns4:OBJECT_ID = $OBJ_ID_VAR and $y/ns4:OBJECT_ID=$OBJ_ID_INNER_VAR
        return <objectVersion>{ $y/ns4:OBJECT_VERSION_NUMBER }</objectVersion>
but ora:processXQuery dosen't accept more than two arguments. Is there any work around?

Answer 1

Create a specific xml schema for your xquery as a input and pass that. Extract the required values from xml in your xquery.
