in thread Not able to replace element value using XML::Twig

Thanks , the file player.xml should be replaced with the change but it is not. I am able to see the change using $twig->print. Hope that makes sense.

    Ahh, that's the problem. You have to tell Twig explicitely to save it to a file (after all, a Twig user might not want to change the xml but just parse it, or print it to the screen).
    When I add 
     
$twig->print_to_file("player.xml");

    at the end of your script instead of the "$root->print;" line, the file on disk gets updated too

      Thanks , I did try with print_to_file but my code gives an error that cannot locate the function for object.
      Also even though I am creating an object of type XML::Twig but the object is being created of type XML::Twig::Elt which is a subclass of XML::Twig.
      That's another reason the function is not being located by the created object

        my $twig = XML::Twig->new();
print ref $twig,"\n";
$twig->parsefile("player.xml");
my $root= $twig->root;
print ref $root,"\n";

# prints:

XML::Twig
XML::Twig::Elt

        It seems you are still using $root for the method call instead of $twig. If I use $root->print_to_file instead of $twig->print_to_file, I too get the error message that the function can't be found
