Bpel reads a normalised message as an input but when try parsing the normalised message to take the xml data from its payload using BPEL function
ora:parseEscapedXML(bpws:getVariableData('NormMsg','payload','/ns3:NormalizedMessage/ns3:Payload/ns3:CharacterData'))
the xml generated as an output has root element occuring twice

Hello,
I have the same problem - parseEscapedXML creates double headers if used after getContentAsString (if my payload has special characters parseEscapedXML fails). I used parseXML - it didn't work. And assigning TO level higher didn't work either. I used substring-before(substring-after,..),..) on a payload before applying parseEscapedXML and it solves the problem. But it doesn't seem like a very clean solution. I am new to BPEL. Could somebody advise, please?
Here is my assignment:
<assign name="AssignCustomerEmailEnqueueInput">
<copy>
<from expression="substring-before(substring-after(bpws:getVariableData('QueryRestartOutput','RestartCollection','/ns5:RestartCollection/ns5:Restart/ns5:payload'), '&lt;CUSTOMEREMAILMSG xmlns=&quot;http://xmlns.oracle.com/xdb/FIS&quot;>'), '&lt;/CUSTOMEREMAILMSG>')"/>
<to variable="QueryRestartOutput"
part="RestartCollection"
query="/ns5:RestartCollection/ns5:Restart/ns5:payload"/>
</copy>
<copy>
<from expression="ora:parseEscapedXML(ora:getContentAsString(bpws:getVariableData('QueryRestartOutput','RestartCollection','/ns5:RestartCollection/ns5:Restart/ns5:payload')))"/>
<to variable="CustomerEmailQueueInput"
part="CUSTOMEREMAILMSG"
query="/ns8:CUSTOMEREMAILMSG"/>
</copy>
<copy>
<from expression="substring-before(substring-after(ora:getContentAsString(bpws:getVariableData('CustomerEmailQueueInput','CUSTOMEREMAILMSG','/ns8:CUSTOMEREMAILMSG/DOCUMENT')), '&lt;DOCUMENT xmlns=&quot;&quot;>'), '&lt;/DOCUMENT>')"/>
<to variable="CustomerEmailQueueInput"
part="CUSTOMEREMAILMSG"
query="/ns8:CUSTOMEREMAILMSG/DOCUMENT"/>
</copy>
</assign>
The third copy is there because on ocasion I get double headers on <DOCUMENT..> which is inside payload variable. Does anybody know why it's doing it? Does it depend on XML itself (double header is not always created)?
Thanks,
Yulia
