Try joining the child nodes

my ($node) = $dom->findnodes('/doc/text');
my $text = join '', $node->childNodes();
print "$text\n";

    Thanks poj,

    This works great for me, and I also realized that I can differentiate the type of node that I get (plain text vs. element):

    my ($node) = $dom->findnodes('/doc/text');
my @children = $node->childNodes;
foreach my $child (@children) {
    my $type = ref($child);
    # $type contains the type of the node, ex: "XML::LibXML::Element"
}

    From there, I can have a plain text string (no tags) and a separate list of all the elements embedded.

    Have a great day!

      my $type = ref($child);

      This is a very brittle way of doing it - it's possible that XML::LibXML::Element could be subclassed, and this check would fail, which is why I would recommend against it. It's possible to do $child->isa('XML::LibXML::Element'), but XML::LibXML provides an API to check the node type: $child->nodeType == XML_ELEMENT_NODE (admittedly not a very Perlish way of doing it, but it's based on the libxml2 API).
