   Yes Scott...just meant to explain that I receive an invalid document
   and expat is giving me the "no elements found" message.

   Thanks Scott....I will try the HTTP_url_post() first in the future.

   I had to wrap the xml request in a <!CDATA  tag  to get it working
   (build string xml within xml e.g  <dataxml>string<dataxml>  where
   string=xml).

   Ok, I tried to set the pointer to an IFS file (instead of %addr(SOAP))
    and lost the first 2 characters. Solved it by having 2 blanks first
   in the file.

   I just needed to add 2 different soap action in the same program (a
   dialog with the web service) . I have now tested it and  it works
   fine.

   Again Scott...thanks for your answere!

   Best regards
