Need to extract data from a text file or a
web page? Or do you want to make your
application more flexible with user-defined
commands or search strings? Do
regular expressions and lex/yacc make
your eyes blur and your brain hurt?
Pyparsing could be the solution. Pyparsing
is a pure-Python class library that
makes it easy to build recursive-descent
parsers quickly. There is no need to
handcraft your own parsing state machine.
With pyparsing, you can quickly
page scrapers, logfile data
extractors, or complex data structure or
command processors. This Short Cut
shows you how!
