It does. But... (see below) > I was fixing a change that occured in v1.16.

As far as I see it, now it is not possible anymore to distinguish between "empty element" (returns "") and "element not present" (returns null). Many of our applications use these tests. Or do you mean that putting xml:space="preserve" at the root element, we will continue to be able to use these tests without any side-effects? The key question is: can we get the v1.15 behavior back by putting xml:space="preserve" at the root node? > My 1.20 change merely restored the behavior of returning null.

Sorry if I sound confused, I'm just trying to determine, what the exact consequences are for our applications :) cheers, Ulrich -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
