XML::Twig is built on Expat, and is especially good at processing large files one element at a time instead of loading the whole file into memory first. For instance, if your data consists of multiple independent <NODE1> elements XML::Twig can be set up to process them individually and so save memory. Take a look here http://www.xmltwig.com/xmltwig/ But if you are hoping to write something that is faster than MSXML or Xerces you may be unsucessful. Perl also has XML::LibXML and XML::Xerces modules as well if you want to try those. What do you need to do with the data? It may be possible with regular expressions if the data is consistently formatted.
