Hi,Today I was reading the tutorial on E4X (http://www.w3schools.com/e4x/tryit.asp?filename=note_parsertest_crossbrowser), but I saw this is the crossbrowser version of showing an XML document's node. So I clicked on Try It Yourself. But nothing showed up in Opera.Internet Explorer6.0 was ok, but Firefox and Opera complaint (my firefox theme looks exactly like IE's one, that's why I first said Firefox worked well too).Firefox and Opera just give me a blank screen.And I won't say Your Browser Cannot Handle this.BUT if you change "createDocument" to "open", internet explorer will still work fine, and Firefox and Opera will say Your Browser Cannot Handle this.Is there any solution?
