I'd take a different tack, and loop through the placemark nodes.

I've also assumed the OP wants all coords, rather than the last one as per your example, so have dumped them in a hash of arrays...

my $xml = 'your xml...'; my %coords_by_name; while ($xml =~ m{<Placemark>(.*?)</Placemark>}gs ) { my $placemark_snippet = $1; if ( $placemark_snippet =~ m{(<name>.*?</name>)}gs ) { my $name = $1; while ( $placemark_snippet =~ m{(<coordinates>.*?</coordinates +>)}gs ) { push @{$coords_by_name{$name}}, $1; } } } use Data::Dumper; print Dumper(\%coords_by_name);
I agree with the other comments though, you need a good reason to not use a proper xml parser, the above code won't be very robust, and only supports a fraction of the valid ways you could write that xml.
my name's not Keith, and I'm not reasonable.
