Re: [PLUG] Perl question...

[Andrew Libby <andrew.libby@gmail.com>]

Okay, so if you've got whitespace in your field values, something
more like this might work:

while(<FILE>) {

    # Even though \s matches tabs, I'm trying to focus on
    # multiple whtiespaces OR a tab.   I usually have to play around
    # with greed to make things like this work effictively.  One thing that
    # might make a difference is to place a ? after the first * to
minimize the
    # amount gobbled up by .*

    my($data) =~ /.*(?:\s{2,}|\t)(.*)$/;   
}
