I am trying to extract the text from a nested list of HTML using HTML::TreeBuilder::XPath: 
<ul class="top">
    <li>Level 1
        <ul>
            <li>Level 2
                <ul>
                    <li>Level 3</li>
                </ul>
            </li>
        </ul>
    </li>
</ul>

I can't work out how to get the text of just the current node. For example, this: 
my $tree = HTML::TreeBuilder::XPath->new;
$tree->parse($html);
my @nodes = $tree->findnodes('//ul[@class="top"]');
for my $node (@nodes) {
    my @elems = $node->findnodes('li');
    for my $elem (@elems) {
        my $text = $elem->as_text;
        print "$text\n";
    }
}

gives me the following output, where all text values are concatenated: 
Level 1 Level 2 Level 3

but what I want is: 
Level 1

and then drill down to the next level to get that level's text
