Oxygen XML Editor and XSLT Debugger for Windows

With Oxygen XML Editor you can create and edit documents in different languages. It has particular support for XML. The program adds a new source folding feature to collapse and expand elements.

The user can also define document fragments that can be reused while editing. Oxygen comes with a large number of ready-to use templates for XSL and XML Schema improving its productivity and usability.

The validation feature was enhanced by adding Schematron support. Oxygen can validate XML documents using Schematron schemas and XML Schemas or Relax NG Schemas that contain embedded Schematron rules.
