Regex woes - help, please?
This should be obvious, but I`m stuck. If I run this as a standalone Perl
program the regex
works just as I expect it too. But if I run it from the CGI that it`s part of it
fails under
certain conditions. Here is the regular expression:
$line =~ m/captions*(d+)?s*(d+)?s*:s*(.*?)s*([
])
It`s meant to match the follwoing general things
caption: test caption
caption 100: test caption again
caption 123 456: a third test
The first two wrok perfectly in the CGI. The third matches when this is run
standalone
(e.g.,:
#! /usr/bin/perl -w
$_ = "caption 100 200 : test ";
m/captions*(d+)?s*(d+)?s*:s*(.*?)s*([
])/i;
print "match: $& $` 1: $1 2: $2 3: $3 4: $4 ";
but not when in the CGI. In the CGI the thrid test is not matched at all.
What am I missing? Why would this work standalone and not in the CGI?
Thanks.

Is it possible that the third string doesn`t have a , , or
at the end? Are you getting it from a textarea or something?

All the samples I posted would include the
(or or ) at the end of
the caption. So
caption 123 456: test caption
Works fine in the standalone bit of Perl I first wrote about, but fails in
the CGI. But
caption: test
(or or ) caption 100: test
(or or )
Both match properly in the standalone and CGI scripts.
Long and short of it: no this isn`t an issue with a missing character at
the end. And, yes, the string for the CGI does come from a textarea box.
Note that the CGI does an awful lot of other stuff with the textarea data
and the ONLY thing that doesn`t work is this one particular special-case
that I`ve been describing (caption [number] [number]: blah blah).
Everything else works as it should.
