There is not a way to do this. The exact value of from_work_dir needs to be known prior to evaluating the cheetah environment. If you need to variably define the output location - my recommendation would be to just drop form the from_work_dir attribute and append "; cp something/${foo} $test" to the end of your command - this copy has to be done either way so I don't think this is any less efficient. Let me know if this doesn't make sense and good luck! -John On Wed, Jan 22, 2014 at 2:37 AM, lquintri <Laure.Quintric@ifremer.fr> wrote:

Hello,

I don't know how to use a cheetah variable (#set var) inside a XML tag. I mean when I try to do this :

#set foo = "file.txt" ... <outputs> <data format="txt" from_work_dir="something/${foo}" name="test"/> </outputs>

from_work_dir tag contains "something/${foo}" instead of "something/file.txt"

Is there a way to do this ?
