Re: XML-Twig: more efficient tree processing

[mirod]

Is there a way to do this during the foreach loop?

most likely

That's about all I can say based on the information you gave. To really answer the question, I would need to see a little bit of code. Do you set handlers on typeC? From your explanations I half-suspect you load the entire tree in memory, but really I have no way to know.

Here's the nutshell version of what the code does:

my $twig = new XML::Twig ( TwigRoots
                              => { '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;
    }
}

Do you have a $twig_.purge at the end of processColumns?

For what I am doing, I am pretty much done with the processing once I hit the end of processColumns.

Is there a way to free up things while I am in the processColumns loop?
