Re: [Pyparsing] Matching everything up to a point.

[Poromenos <por...@po...>]

That works, thanks a lot! :/ I was doing

task = Words(alphas + " ")

expression = task + SkipTo("on").setResultsName("taskDesc") + \
   "on" + \
   date.setResultsName("taskDate")

and it wasn't working. Now it works like a charm, although I have run
into some weird bugs which I have reported.

Thanks again.
