I like oxygen as well. I just have a real problem with actually *buying* an editor.

Hi Norm. Having downloaded Oxygen 3 and not really tried it very much, I downloaded Oxygen 4.2 last night because the need for an XML editor with RNG validation and RNG-assisted editing had become acute.

So far it works well for validating valid documents :) the messages are cryptic for invalid ones (eg, 'required attributes missing'. Yes, but which ones?), and it seems to offer all possible elements rather than just the ones that a schema says can go in a particular place. But its useful even so, and is being actively developed, so I am happy.

If you like Oxygen then you may be interested to learn that Cladonia Limited, the publisher of Exchanger XML Editor, has released a free XML Editor for use in a non-commercial environment called Exchanger XML Lite.
