[rrd-users] rrdrestore and annoying error messages

[Sean Whitney]

if rrdrestore finds a error it spits out an error similar to 

ERROR: line 210: expected <ds> element but found </cdp_prep>

Which is annoying because line 210 isn't the line number in the file, but the xml parser line number.

Anyway I found this script useful to finding the incorrect element.

use XML::LibXML;

my $parser = XML::LibXML->new( line_numbers => 1 );
my $xml = $parser->load_xml( location => '<filename>' );
foreach my $nodes ( $xml->childNodes ) {
    hasChild($nodes);
}

sub hasChild {
    my $nodes = shift;
    if ( $nodes->hasChildNodes() ) {
        foreach my $node ( $nodes->childNodes ) {
            my $line    = $node->line_number();
            my $nodeStr = $node->nodeName();
            my $nodeval = $node->to_literal();
            print "line $line :: $nodeStr :: $nodeval\n";
            hasChild($node);
        }
    }
}

I'm sure someone could write a much better script, but here is my solution.
