in reply to XML-Twig: more efficient tree processing

maybe using flush Link cpan XML::Twig:

... Once the element is completely processed you can then flush it, which will output it and free the memory ...

so something like this:

my $twig = new XML::Twig ( TwigRoots, pretty_print => 'indented',
                              => { 'tables/table'    => \&processColum
+ns,
                                   'views/view'    => \&processColumns
+ } );
$twig->parsefile($SCHEMAS);
$twig->dispose;

sub processColumns {
   my( $twig, $tableTwig) = @_;

   my @colList = $tableTwig->find_nodes( "columns/column");
   foreach $x ( @colList){
      blah;
   }
   $twig->flush;
}

I tried that. All is seems to do is spit back out the XML on the terminal output (unless it's suppose to do that). I am reading the XML for extracting info then I am done, so printing the tree serves no purpose. This is like closing a file after reading for input; There is no need to print the file when the file is closed.

Is there a way to flush silently?

It is suppose to do that, just change:

$twig->flush;

to

$twig->purge;
