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.
DocBook is an XML vocabulary which enables you to create document content in a presentation-neutral form that captures the logical structure of the content. Using the DocBook Project XSL stylesheets, you can publish DocBook content as HTML pages and PDF files and other formats, including man pages, HTML Help, and JavaHelp.
DocBook XSL Configurator is an umbrella project currently consisting of three similar Java Swing applications used to create DocBook XSL customization layers, run external subprocesses that format DocBook XML, and view the results. Users click through tables, select parameters, edit those parameters, include the customization layer in a project, write out the customization layer as an XSL file, and apply the XSL to the project's XML using the project's specified XSLT processor. DocBook XSL Configurator then runs a project's FO processor, PDF/PostScript viewer, HTML viewer, or man page viewer as an external subprocess.
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.
EditiX Lite is a powerful and easy to use XML editor, visual schema editor and XSLT debugger. It is designed to help Web authors and application programmers take advantage of the latest XML and XML-related technologies such as XSLT/FO, DocBook, and XSD Schema. It has real-time XPath location and syntax error detection, context syntax popups supporting DTD, Schema, and RelaxNG, and support for multiple templates and project management.
RefDB is a reference database and bibliography tool for SGML, XML, and LaTeX documents. Command-line tools allow interactive or scriptable access to the data which are stored in a SQL database. RefDB can also be accessed through a Web interface, a SRU interface, or via editor extensions (Emacs/vim). Libraries for Perl and PHP are available for programmers. RefDB provides sophisticated character encoding handling, using Unicode by default.
