Re: [Pyparsing] whitespace related question

[stefaan.himpe <ste...@gm...>]

Hello, and I have one follow-up question,

The solution I had was able to parse tables with
empty cells, but after incorporating your suggestions
this no longer works.

At first I expected it would be trivial to extend the
parser to handle empty cells, but so far I haven't managed
to get something working :(

I have tried to extend the list_of_cols definition in many ways
and I have tried to replace + with ^ in some places... I am
still missing some fundamental insights in how pyparsing works
to unravel this little mystery.

I'd be really grateful for some input.

Best regards,
Stefaan.


to given an idea of some of many attempts (replace list_of_cols in the 
earlier posted code)

list_of_cols = p.delimitedList(p.Word(" \t") | p.Regex(r"[^#\n\r]+"), "#")

or

list_of_cols = p.delimitedList(p.Regex(r"[^#\n\r]*"), "#")
