XQuery Update Facility

[jlemptoz]

Hello,
I would like to use XQuery Update Facility to transform a message in a camel
route, but I get an error message : Unexpected token "copy" in path
expression.
I'm using camel version 2.8.5, and XQuery runs correctly with "FLWOR"
syntax. Is Update Facility supported ? Is there any instruction or component
missing ? 

I explain what I'm trying to do (simplified example) :
This is the incoming message :
<Data>
  <Item>
    <ItemCode>1234</ItemCode>
    <ItemName>abc def</ItemName>
  </Item>
</Data>

I want to change value of node "ItemName"
My xquery program :
declare variable $in.headers.NewItemName  external;
copy $data := //Data/Item
modify ( replace value of node $data/ItemName with $in.headers.NewItemName )
return
<NewData>
{$data}
</NewData>

I tested it with xqilla, it gives the expected result :
<NewData>
  <Item>
    <ItemCode>1234</ItemCode>
    <ItemName>ABCD EFGH</ItemName>
  </Item>
</NewData>

My camel route :
<from uri=&quot;imap://my.mail.server....
&lt;setHeader headerName=&quot;NewItemName&quot;><simple>ABCD
EFGH</simple></setHeader>
<convertBodyTo type="String"/>
<to uri="xquery:test1.xquery"/>
<to uri="activemq:queue:test"/>

Thanks for any help.
