If not use StAX.Īs for the question about XML being the best choice, it depends on the information you are storing. I'd say consider JAXB if you've been spending a lot of time writing XML schemas. DOM like but with classes that represent you XML grammar instead of any XML grammar so it is easier to use. JAXB will load the doc into a tree of objects. If the XML doc as a schema then JAXB can generate custom classes for all of your XML types. You deal with pieces like in SAX (low memory overhead) but with a much easier programming model. You call a method to ask for the next element of the doc. Entire document gets read into a in memory tree. Slightly difficult to use but low memory over head.ĭOM = old object tree based parser. Each element fires an event which calls a method you write.
