There are two main schools of parsing XML files: using SAX and JAXP. SAX is a stream oriented parsing technique. It means that you read a file tag after tag and can't go backward. It's quite simple and fast but using it to realize more advanced tasks might be difficult. JAXP on the other hand represents the document as an object tree (DOM structure). It's slower and needs more memory but it's often easier to use in complex manipulation of XML files. Knowing both techniques is the software-engineer's 'must know'.

it's SAX and DOM, not SAX and JAXP. JAXP includes both SAX and DOM (and others). en.wikipedia.org/wiki/Java_API_for_XML_Processing

JAXP is not DOM. JAXP is a set of API that provides parsers supporting both SAX and DOM.
If its XML file that you want to read quick and dirty....here are the options...
DOM Parser
SAX Parser
Pull Parser
JAXP & JAXB

Frankly i have not used Memory mapped IO, but have been working with Buffered Reader for the same purpose with no probs....
