I distrust modules?
Dunno. I'm a fan of C programming and like doing stuff myself.
Granted HTML is free form, but I'm parsing a webpage whose format likely
will not change anytime soon, and if it did, even if I was using a module I
would still need to fix up the script.
I know exactly was format the HTML page will be in, and just need to extract
some values from it.
The page got a lot of junk before the data, so I need to find a specific
pattern and extract data from the next chunk of HTML.
Extraction is fairly simple RegEx, so complex modules aren't really
required.
The flag solution works well.
I may take a quick look at the modules...
Thanks.

Real Perl programmers don't use indices. At least, not like that. But
let's say you want to process the lines after a pattern matches, but
not the matching line or the ones before. One straightforward way is
to set a flag:
my $found; # starts out false
foreach (@input) {
if ($found) {
# $_ holds one of the lines you want to process
&deal_with($_);
} else {
# Test $_ for the pattern
$found = m/pattern/;
}
}
warn "Hey, pattern never matched" unless $found;
