. and other ham fist-ed attempts while I grasp at straws. I cannot figure out for the life me what $path I should use in the setNodeText call.

Small program to test one function, like (this should probably be 3 different programs) 

#!/usr/bin/perl --

use strict;
use warnings;

use XML::XPath;

Main( @ARGV );
exit( 0 );

sub Main {
    use XML::XPath;

    my $xc = XML::XPath->new(xml  => SampleXML() );
    print "ORIGINAL XML\n";
    print $xc->findnodes_as_string('/'), "\n\n";
    
    print "//blocks MATCHES MANY NODES \n";
    $xc->setNodeText( '//blocks', ' blah blah ' );
    print $xc->findnodes_as_string('/'), "\n\n";
    
    print '//cidr-map-to[@name="AKA Edge"]/blocks MATCHES MANY NODES',
+ "\n";
    $xc->setNodeText( '//cidr-map-to[@name="AKA Edge"]/blocks', ' aha 
+42 ' );
    print $xc->findnodes_as_string('/'), "\n\n";
    
    print '//cidr-map[2]/cidr-map-to/blocks  MATCHES ONE NODE', "\n";
    $xc->setNodeText( '/Product/cidr-map[2]/cidr-map-to/blocks', ' eur
+eka ' );
    $xc->setNodeText( '//cidr-map[2]/cidr-map-to/blocks', ' eureka ' )
+;
    $xc->setNodeText( '//cidr-map[@name="Prod Internal Actual"]/cidr-m
+ap-to/blocks', ' eureka ' );
    
    print $xc->findnodes_as_string('/'), "\n\n";
}
