Hi--

I have this 3-level HoH that I would like to print using XML-Twig. The hash stores a fair amount of info (about 20MB over 14K rows) and I am able to print it out by using XML-Twig to build the whole tree then printing that tree.

Something like: 
foreach key (keus %hash)
    some data manipulation
    build some XML nodes onto tree
    foreach key2 (keys %{$hash{key}})
        some data manipulation
        build some XML nodes onto tree
        foreach key2 (keys %{$hash{key}{key2}})
            parse some prepared XML snippets
            graft onto tree
        end
    end
end

tree->print

This works fine and dandy, but as my hash is getting more and more rows, the slower and slower it runs. Plus the memory allocated goes through the roof, and lately, I've been getting segmentation faults (out of memory is a guess).

Is there a way using XML-Twig to flush(?) the output at the end of a loop step to create the output tree as it is looping through, vs. holding the entire tree in memory before commencing the print?

I've looked around for answers, but most of the Twig tricks are parsing-centric.

Thanks.
