Hi, You have this module (mymod.py) print "First import" xmlfile=.... If you import mymod the second time, you won't see "First import" again. The code without indentation gets executed only once. You can access your file with mymod.xmlfile. HTH, Thomas -- Thomas Güttler, http://www.thomas-guettler.de/ -- http://mail.python.org/mailman/listinfo/python-list
