Oxygen XML authoring tools come in two varieties - Oxygen XML Editor and Oxygen XML Author. Each of them has a couple of subvarieties, so when you plan to buy any of them, you should pay attention not only to the price but also to the set of features included.
Oxygen XML Author (or as its full name is: <oXygen/> XML Author), which is the topic of this review is the more light-weight variety and naturally it costs less. Still, it has a lot of features you will need when you edit XML files and mainly XML documentation. Even Oxygen XML Author Enterprise Edition (the more expensive Author version) is a full-fledged XML editing environment.
If you need more features than what the basic set offers, you can get Oxygen XML Editor. The Editor version includes some advanced features but if you need it only to edit existing XML documentation, you might never use them.
Both Oxygen XML Author and Oxygen XML Editor offer a free 30-day trial. You need to register, download the version of your choice and request a license key. You will get the license by email – copy and paste it and you can go.
