Thanks for the info, I will download that program later so I can build a re (i hope) Because I can't wait for that re, I have made a non re solution what is working for now. for a in bla.split(): if a.find('BlaObject')<>-1: print a[11:].replace("'","").replace('"',"").replace(",","") (I know this is not the best way, but it helps me for now) -- http://mail.python.org/mailman/listinfo/python-list
