The "normal" way to traverse a DOM doesn't use the NodeList thing. The NodeList stuff isn't even threadsafe in Xerces. NodeLists are also slower due to having to calc the number of children and such. Normally, you call el.getFirstChild() and the child.getNextSibling() which could easily use deferred parsing. If someone uses the NodeList things, then yes, you would need to pull everything in at once, but using normal traversals, you wouldn't. -- Daniel Kulp [email protected] http://dankulp.com/blog
