[kepler-users] problem with the URL To Local File actor and a symbol

[Trina Myers]

Hi All,

I have a workflow that extracts xml files from a servlet and transforms the
data within using the XPATH actor. It has been working very well until I
have tried to import 2 elements from the site. The only difference between
the URL in question and the working URL is the use of "|" (separating
max|avg). 
If I download the xml file with both elements and use the absolute address
to the file on the local machine the workflow works fine (extracting both
the avg and max data as required), so I am sure the problem is at the URL to
local file actor.

I would appreciate any guidance
Cheers
Trina
