Hello Fredric,
 
Thank you for your answer. I am experiencing some problems with the code you suggested. The 
 
end = text.search("\W", pos + " 1 char", regexp=True)
gives me this as a result: TclError: bad text index " 1 char". I tried some other options for the " 1 char" 
part but the result was the same. Any ideas? I am using Windows XP and Python 2.5.
 
Thanks again for the answer, 
 
Alex
