See all the way down here: http://ode.apache.org/headers-handling.html What you can do is use a literal to first prepare your header element. Something like: <copy> <from><literal><myns:headerElemt></myns:headerElmt></literal></from> <to variable="tempEltmVar"/> </copy> <copy> <from>$ode:pid</from> <to>$tempEltmVar/myns:headerElemt</to> </copy> <copy> <from>$tempEltmVar</from> <to variable="Variable1" header="someHeader"/> </copy> Cheers, Matthieu > Thanks, > > Mark > > On Wed, Apr 23, 2008 at 8:05 PM, Matthieu Riou <[EMAIL PROTECTED]> > wrote: > > > On Wed, Apr 23, 2008 at 3:53 PM, Mark Panahi <[EMAIL PROTECTED]> wrote: > > > > > Hi Paul, > > > > > > Actually I need for a research project I'm working on. i am developing > > an > > > extension to an ESB that among other things collects QoS data about > > hosted > > > services for a given process.
