How to find child elements of a specified parent using XML::LibXML?

Question

Suppose I have a XML file

<table>
    <person>
        <ID>1</ID>
        <Name>Adam</Name>
    </person>
    <student>
        <Subject>Math</Subject>
        <Marks>90</Marks>
    </student>
    <employee>
        <ID>7</ID>
        <Name>Bill</Name>
    </employee>
</table>

I want to get the child elements of the table element. ie the output should be person , student and employee . How do I do this with the XML::LibXML module in Perl?

Answer 1

for my $node ($doc->findnodes('/table/*')) {
    say $node->nodeName();
}

or

use XML::LibXML qw( XML_ELEMENT_NODE );

my $root = $doc->documentElement();
for my $node ( grep { $_->nodeType() == XML_ELEMENT_NODE } $root->childNodes() ) {
    say $node->nodeName();
}
