Oxygen is an XML Editor and XSLT Debugger written in Java with Unicode
support. It offers end tag auto-completion and a powerful code insight. The code
insight can follow a DTD or an XML Schema or even can learn the structure from a
partial edited document. An important thing is manipulating XML content and XSLT is
the normal way to do this. XML and XSL documents can be easily associated one with
the other and the transformation results can be viewed as text or HTML. Oxygen XML
Editor provides a visual schema editor for W3C XML Schema and Relax NG schema
designed to simplify the development and understanding of the schema files. Oxygen
validates XML, XSL and XSD content, reporting errors with description and line
number information. More documents can be logically organized in projects. It comes
with the latest Docbook DTD and stylesheets. Includes the Apache FO Processor, being
able to generate PDF and PostScript. Other FO processors can be configured as
plugins. Oxygen provides a special layout when entering in debugging mode to show
the source and the stylesheet documents side by side and to show also the results
and special debugging views. Debugging and profiling can be done using Xalan 2.5.1, Saxon6.5.4 or
Saxon8 transformation engines. All debugger capabilities are provided (step into,
step over, step out, run, run to cursor, run to end, pause, stop). XPath expressions
are evaluated automatically during debugging. The output is dynamically presented as
it is generated by the transformation process. A complete diff and merge solution is
also available in Oxygen. It offers both directory and file comparison, 6
file diff algorithms, multiple level diff support, synchronized scrolling and change
guide lines, easy invocation of the diff action from project panel or from the
editors' contextual menu. Oxygen provides support for importing database content,
Microsoft Excel sheets and legacy text data files into XML documents.
