I'm a pretty simplistic user of the DOM, but the things that have caused me to jump through the most hoops are as follows, in order of the amount of work they have caused me. (My apologies if DOM 2 or 3 already solves these -- I admit I haven't kept up with the specs.) 1) Lack of DTD info. 2) Lack of normalization. A normalize function that just slaps text nodes together is great for editors, but useless for data-centric people like me. I want a way to normalize everything (text, cdata, entity references, etc.) so all that's left are element, attribute, and text nodes. 3) Lack of serialization/printing. (Solved in DOM 3, if I remember correctly.) 4) Lack of a way to create an empty document. (Solved in DOM 2 or 3?) 5) Lack of a way to create new entities. This is very useful if I want to create unparsed entities as a way to return BLOBs from a database. Solved in the new DTD stuff, perhaps? But none of this is worth several months worth of effort. As I recall, (1) took several weeks of work spread out over a year, (2) was annoying and took about a week in the midst of learning Java, XML, and the DOM, (3) and (4) weren't hard and took about a day each, and (5) I still don't have a solution for. -- Ron
