I didn't see you assign a value to %forecast but you can loop through it,why?

I am not sure if you got the entire code but after the loop through, 
there are more codes which when it encounters tags, it builds %forecast 
hash as below

sub StartTag {
my ($p, $tag) = @_;

push @curr, $tag;

if ($tag eq 'TEMPERATURE') {
$type = $_{TYPE};
$forecast{$type}->{deg} = $_{DEGREES};
}
}

sub EndTag {
pop @curr;
}

sub Text {
my ($p) = shift;

return unless /\S/;

s/^\s+//;
s/^\s+$//;

if ($curr[-1] eq 'OUTLOOK') {
$forecast{outlook} .= $_;
} elsif ( $curr[-1] eq 'TEMPERATURE' ) {
$forecast{$type}->{val} = $_;
}
}
