xpather.pl looks like it will prove really useful. Thanks!

I'm drifting way off topic here, but what I've got now is probably the most inefficient way of dealing with the problem:

My XML looks like this:

<user>
        <address name="1">
                <entry name="Address line 1">street</entry>
                <entry name="Address line 2">suburb</entry>
                <entry name="Postal code">code</entry>
        </address>
        <address name="2">
                <entry name="Address line 1">street2</entry>
                <entry name="Address line 2">suburb2</entry>
                <entry name="Postal code">code2</entry>
        </address>
</user>

I want to extract each of those address lines into variables, so I'm doing this:

    my ( $addr_1_line_1, $addr_1_line_2 );
    for my $node ( $user->findnodes( q{ ./*[ local-name()="address"
                                     and @name = "1"] } )) {
        for my $subnode ( $node->findnodes(
                    q{ ./*[ @name="Address line 1" ] } ) ) {
            $addr_1_line_1 = $subnode->textContent();
        }    
        for my $subnode ( $node->findnodes( q{ ./*[ 
                            @name="Address line 2" ] } ) ) {
            $addr_1_line_2 = $subnode->textContent();
        }    
  }

It does appear to work, but is there a more efficient way of doing this?
