OK, after a short amount of investigation, I found that this program works:
[CODE]
use strict;
use warnings;
use XML::LibXML::Reader;
my $xml = 'Lexems.xml';
my $reader = XML::LibXML::Reader->new( location => $xml ) or die "cannot read
$xml";
while ( $reader->nextElement( 'Lexem' ) ) {
my $id = $reader->getAttribute( 'id' ); #works fine
my $doc = $reader->copyCurrentNode(1);
my $timestamp = $doc->getElementsByTagName( 'Timestamp' );
my @lexem_text = $doc->getElementsByTagName( 'Form' );
}
[/CODE]
Note that you can also use XPath for looking up XML information.
