Here is a different approach using
XML::Twig. I consider this a more brute-force, less elegant solution than that provided by
GrandFather. However, it illustrates the TIMTOWTDI-ness of Twig; perhaps you are more comfortable thinking of this as looping through elements, rather than the more powerful use of handlers (as I currently am). I have borrowed
GrandFather's cleaned up XML text.
use strict;
use warnings;
use Data::Dumper;
use XML::Twig;
my $xmlStr = <<XML;
<config>
<one id="msn" type="shopping">
<traffic>
<daily value="on" />
<weekly value="off" />
<monthly value="off" />
</traffic>
</one>
<one id="movies" type="entertainment">
<traffic>
<daily value="on" />
<weekly value="off" />
<monthly value="on" />
</traffic>
</one>
<one id="espn" type="sports">
<traffic>
<daily value="on" />
<weekly value="on" />
<monthly value="on" />
<hyper value="true" />
</traffic>
</one>
</config>
XML
my @ids;
my $t = XML::Twig->new();
$t->parse($xmlStr);
for my $one ($t->root()->children('one')) {
push @ids, $one->att('id');
}
print Dumper(\@ids);
__END__
$VAR1 = [
'msn',
'movies',
'espn'
];
