Oxygen XML Editor

Oxygen XML Editor (often styled as <oXygen/>) is the premier, professional, multi-platform XML editor used globally by technical writers, information architects, and software developers. It is a comprehensive suite of tools for XML authoring, development, and publishing for various structured content standards.

The current major version is Oxygen XML Editor 27 (or sometimes 28.0, depending on the specific product line).

Key Features and Use Cases

Oxygen is the gold standard because it combines a friendly authoring environment with deep developer tools:

• Visual Authoring (WYSIWYG): The Author mode provides a familiar, word-processor-like interface (driven by CSS) for editing XML documents. This allows non-technical content creators to work on structured content (like DITA or DocBook) without seeing the raw XML markup.

• Comprehensive XML Support: It supports virtually all major XML-related standards:

  • Validation: DTD, XML Schema, Relax NG, Schematron.

  • Transformation: XSLT (1.0, 2.0, 3.0), XQuery.

  • Structured Authoring: Built-in support for DITA, DocBook, TEI, JATS, XHTML, and more.

• XML Development Platform: Includes powerful tools for developers:

  • XSLT/XQuery Debugger and Profiler: Step-through debugging to find errors and bottlenecks in transformation scripts.

  • Schema Editor: Visual and text-based tools to design and edit XML Schemas and JSON Schemas.

• Single-Source Publishing: Convert validated XML content into various output formats, including HTML5, PDF (via XSL-FO and FOP/PDF Chemistry), EPUB, and WebHelp, often using the bundled DITA Open Toolkit.

• Modern Data Support: Includes robust support for editing, validating, converting, and querying JSON and YAML documents alongside XML.

• AI Integration: Features like the Oxygen AI Positron Assistant can help improve content quality, suggest new text, and handle translations (via a plugin and RAG architecture).
