[Pyparsing] parse challange, at least for me:)

[Werner <wer...@gm...>]

Hi,

I like to parse many .py files and check if any of the following is 
present in it:

test = """# Tags:         phoenix-port, unittest, documented, py3-port"""

A file might or might not have this comment line somewhere at the top, 
and it might have one or more of the tags.

I like to report on the file name and what tags are present in it, the 
use of this is a check list of what modules have been converted/been done.

On the above test string I tried this, but it only reports on the first.

allTags = pp.Literal("# Tags:") +\
     pp.Literal("phoenix-port").setResultsName('phoenix') |\
     pp.FollowedBy("unittest").setResultsName('test') |\
     pp.FollowedBy("py3-port").setResultsName('py3') |\
     pp.FollowedBy("documented").setResultsName('doc')


result = allTags.parseString(test)
print(result)

The other problem I have when using 'parseFile' is how to tell it to 
ignore everything before or after, or even all if the '# Tags:' line is 
not present.

Hopefully someone can push me in the right direction.

Werner
