Re: data extraction from a variable

I'd just do something like:

my ($variable, $first, $second);
$variable = some_data_provider();
if ($variable =~ /: ([0-9.]+) ([0-9.]+)/) {
    ($first, $second) = ($1, $2);
    print "Found the values $first and $second!\n";
}

Amusing note: I accidentally left off the / in the </code> tag and got one of those horrible-looking newbie posts. I wonder if the newbies are enclosing code in a pair of <code> tags?

Yes, sometimes they screw up the closing tags. But most of the times, they don't use any tags at all.	[reply]

thanks robiticus !! I used your suggestion with a minor change as I realised that my example line wasn't a 100% accurate example (oops) `if ($variable =~ /:\W{1,15}([0-9.]+)\W{1,15}([0-9.]+)/) { ($first, $second) = ($1, $2);` [download] worked out how to effectively ignore the spaces between everything. again many thanks for helping out a PERL newbie.
