oXygen is an XML editor that supports any XML document, and works with XML Schemas, DTDs, Relax NG schemas, and NRL Schemas. It has powerful transformation support that allows you to edit XSLT and XSL-FO documents and to obtain documents in the desired output format (such as HTML, PS, or PDF) with just one click. It also includes a complete Subversion client, support for flattening XML Schemata, an XML Schema instance generator, integration with the X-Hive/DB, MarkLogic and TigerLogic XML databases, editing actions on the diagram, and a rename refactoring action.
Syntext Serna is a highly customizable, multi-platform, pure XSL-driven WYSIWYG XML content editor. It looks and works like a conventional word processor, yet it gives you much more flexibility to alter or reuse content while keeping its integrity intact. It lets you collaborate on compound documents that contain embedded data from various sources. Content is viewed as an integrated whole that is intuitively transparent to authors.
EditiX is a cross-platform and multi-purpose XML editor and XSLT debugger (1.0 and 2.0), which helps Web authors and programmers use XML and XML-related technologies, such as XSLT, FO, and XSD schemas. It provides a lot of functionality within a refined IDE, which guides the user with intelligent entry helpers, and has real-time XPath location and syntax error detection. It allows the user to apply an XSLT or FO transformation, and shows the result in a separate view. It includes default templates for XML, DTD, XHTML, XSLT, XSD, XML RelaxNG, SVG, MathML, and XML FO. It can generate schema W3C, DTD or RelaxNG from a document instance.
PDFreactor is a formatting processor to convert HTML and XML to PDF. It uses Cascading Style Sheets (CSS) to define page layout and styles. It allows you to dynamically generate PDF documents such as invoices, delivery notes, shipping documents, or print versions of Web content on-the-fly. Vector graphics (SVG), barcodes, MathML, XSLT, and CMYK colors are supported. All common J2EE application servers are supported. Complete .NET, PHP, Perl, Python, and Ruby APIs are included. Direct integration into automatic build processes using Apache Ant is also possible.
4Suite XML is a Python-based toolkit for XML application development. It features a library of integrated tools for XML processing, implementing open technologies such as DOM, SAX, XPath, XSLT, XInclude, XPointer, XLink, XUpdate, RELAX NG, and XML/SGML Catalogs. The RDF and Repository components of 4Suite are separate packages that must be installed separately, on top of 4Suite XML.
AsciiDoc is a text document format for writing short documents, articles, books, and UNIX man pages. AsciiDoc files can be translated to HTML and DocBook markups using the asciidoc(1) command. AsciiDoc is highly configurable: both the AsciiDoc source file syntax and the backend output markups (which can be almost any type of SGML/XML markup) can be customized and extended by the user.
Treebeard is an XSLT IDE that allows you to load an XML file and an XSLT file (from the Web or from the local file system), edit either file, and then perform transformations. Some features include syntax highlighting, a pluggable XSLT transformer, a template browser, SAX transformations (so you can transform large files - 4MB tested), regular expression find, and displaying transformation results in HTML or plain text.
