PerlingTheUK has asked for the wisdom of the Perl Monks concerning the following question:

Dearest Monks,
I have used XML::DOM for some XML File manipulation. Usually this was a open, alter and save job and XML::DOM is most perfect for this. But however it is not implemented very good for reducing memory and the 40 MByte files I need to alter just exhaust all available memory. Are there any similar models that are implemented natively and offer a conveniently easy interface?
