In grabbing a webpage from a foreign server I need to modify any relative urls to abosolute.
The code snippet below works but I was wondering if there is a better way.
.....
my ($urltop) = 'http://www.somewhere.com/';
my ($urltodir) = 'http://www.somewhere.com/folder/';
my(@matches) = ($content =~ /href="([^"]*)"/gi);
foreach my $match (@matches) {
if ($match =~ /^http/i) {
## absolute leave alone
} elsif ($match =~ /^\//) {
$content =~ s/href="$match"/href="$urltop$match"/gi;
} else {
$content =~ s/href="$match"/href="$urltodir\/$match"/gi;
}
}
I could do the leading slash stuff with:
$content =~ s/href="^\/([^"]*)"/href="$urltop/$1"/gi;
But I can't figure out how to do the other matches without the foreach.
Thanks for any clues
