Question

I have the following:

my $string='<entry><name>Bob</name><zip>90210</zip></entry>';

my $parser=XML::LibXML->new(); 
use HTML::Entities;
my $encodedXml=encode_entities($string,'&\'');

my $doc=$parser->parse_string($encodedXml);

foreach my $text($doc->findnodes("//text()")){
print $text->to_literal,"\n";
}

This prints out ‘Bob’ and ‘90210’;

How do I get the actual node names…I need a way to get all the nodes within my xml tree….ie ‘name’ and ‘zip’

Answer 1

Text nodes don’t have names. Perhaps you want the name of the parent?

I think this will work:

for my $node ($doc->findnodes('//text()')) {
   print $node->parentNode()->nodeName(), ": ", $node->nodeValue(), "\n";
}

I would use

for my $node ($doc->findnodes('//*[text()]')) {
   print $node->nodeName(), ": ", $node->textContent(), "\n";
}

Note: This later version combines all the text children of the element, so it’s not equivalent if a node has more than one text child. They should be equivalent for you, though.
