Hi Mike, Many thanks, that was exactly what I was looking for. I didnt have the chance to see the code but I did some test and it seems to be working fine. At least it returns what it is expected. I have in mind to build some user interface to evaluate e4x expression, I'll back to the list as soon as I have something to show.
BTW did Alex post anything regarding this topic in his blog? Cheers, Diego. On Tue, 31 Oct 2006 16:47:11 +1300, Michael Labriola <[EMAIL PROTECTED]> wrote: > > Diego, > > Here is a starting point.
