Ok, so I'm working on another node-grabbing routine. This time
I want to parse my personal nodes to extract the titles of
nodes I've added that are "original nodes". By original I mean
not in reply to another node.
So I am testing using a local file and a loop that looks like this:
while (<>) {
my $node;
$node = $1 if /^<TR bgcolor=.*>([^<]*)<\/a>/io;
next if $node =~ /^re:/io;
print "Found original: $node\n" if $node;
}
This works just fine. However I am wondering, as I often
do, is there Another Way To Do This?
Basically I need to match all titles that don't start with
"RE:". According to page 230 of Mastering Regular Expressions,
this concept is called lookbehind, and it also tells me
I Can't Do That In Perl.
So I find myself wondering; WWCABD? (What would chromatic
and btrott do? <g>)

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
