Downloaded the latest version of the
<oXygen> XML IDE last night and was impressed with what I saw. <oXygen> is cross platform and supports both Linux and Windows as well as the Eclipse IDE. One things that I have always like about the Altova XML Spy suite (
that they remove from their community edition) is the ability to collapse an element in the edit interface. This comes in really handy when working with complex documents. <oXygen> also has a nice Schema interface, XPATH 2.0 interface and diffing tool.
Altova charges big bucks for all of this functionality. The equivalent functionality in <oXygen> for 1/4 the price, cross platform to boot? Summary good deal!
NOTE: If you are running <oXygen> under Linux you do need a Sun JVM. The JVM that comes with the Fedora Core 4 & 5 distributions is not supported. To make it work in Fedora Core, rename the supplied /usr/bin/java binary to java.old and then include a link called java to the SUN JVM.
