It's been 4 years since I've written in Perl. I'm having a bit of
trouble with pattern matching.
I have a set of strings that are parsed from a file created by
extracting data from a database. Because some of the fields in the data
are empty and some are not, some strings are empty, some not. I want the
code to process all strings that aren't empty. All strings are NULL
terminated.
So far I've managed to have the code either ignore all strings, or none
of them.
What's the correct pattern match for an empty string (the string is
stored in a scalar)?
