I hate unnecessary attributes. I try to use them only when it refines the meaning of the value of the element. If you create your xml with element values, I think you will have an easier time getting to them. Like this:
<log>
<msg>
<error>
ID not found
</error>
<request>
myRequest
</request>
</msg>
</log>
But sometimes we just have to deal with the hand we are dealt. I found a way to get at your attribute values by registering two TwigHandlers. I'm sure
mirod has a much more elegent solution than this:
use strict;
use XML::Twig;
my $file = 'uncle.xml';
my $twig = new XML::Twig( TwigHandlers => {
'log/msg/error' => \&print_error,
'log/msg/request' => \&print_request,
});
$twig->parsefile($file) or die "can't parse $!\n";
sub print_error {
my ($t, $elt) = @_;
print "ERROR = " . $elt->att('name') . "\n";
}
sub print_request {
my ($t, $elt) = @_;
print "REQUEST = " . $elt->att('name') . "\n";
}
Get Strong Together!!
