Blame the DOM working group (to which I must confess membership), not Sun. The value() of an Element is always null according to the DOM spec. The standard way to get the value of an element is to get the child Text node and get its value. Most DOM implementations have some sort of convenience method to get the text value of a single element ... but sometimes you have to get the text of the entire subtree under the element (which is apparently what Sun's toString() method is doing). In the DOM WG's defense, it is *exactly* this reason for making the value() of an Element null -- Should it return the value of the entire subtree? Should the text come back with markup embedded or not? There was no consensus as to the best way to do it, so we essentially punted. xml-dev: A list for W3C XML Developers.
