( #3333=superdoc: print w/replies, xml ) Need Help??

Assuming gibsonca.xml looks like this:

<abc>fds </abc> <!-- ok -->
<ddd></ddd> <!-- not ok -->
<eee> </eee> <!-- not ok -->

The following program will print "3" and "4".

#!/opt/perl/bin/perl -T
use strict;
use warnings;
use Carp;
use English qw(-no_match_vars);
use Try::Tiny;
use XML::LibXML;

our $VERSION = '0.1';

my $file = 'gibsonca.xml';
my $dom;

open my $fh, '<', $file
    or carp "Can't open $file: $OS_ERROR";

try {
    $dom = XML::LibXML->load_xml(
        {   IO           => $fh,
            line_numbers => 1,
catch {
    print "Error parsing $file";

close $fh
    or carp "Can't close $file: $OS_ERROR";

for my $e ( $dom->findnodes('//*') ) {

    my $t = $e->textContent();
    $t =~ s{\A \s+ \z}{}xms;

    if ( !$t ) {
        print $e->line_number() . "\n";

exit 0;

    [erix]: the annoying thing is that during setup of the 'foreign table' you have to specify all the columns. But that is reasonably automatable (just reading header line, and contruct the needed CREATE FOREIGN TABLE' statement)
    [erix]: it may be easier to just slurp your fils into regular tables. Has other infrastructure advantages also (indexes, constraints etc)
