in reply to Incremental XML parsing

XML::LibXML is a DOM parser and hence wants to read the whole document into memory before doing anything. XML::Parser is a SAX parser and can give you callbacks instead. You might want to look at XML::Twig, which attempts to give you the best of both worlds, giving you subtrees as soon as they become available.
