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.
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.
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.
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.
GXPARSE is not a new XML parser, but is an additional processing layer that makes it much easier to use event-based parsers like the SAX parser. It supports both direct sequential output and random access output (via the Resequencer interface). The random access mode delays output until all input has been processed, but makes it much easier to handle ID/IDREF attributes. GXPARSE maintains most advantages of the event-based parser. Application development and maintenance is considerably easier, but processing is a little slower.
DocBookWiki can display and edit DocBook documents online. It can display several documents at once (a list of books), and each of them can be in several languages. Editing can be done in several modes (like text/wiki, HTML, XML, etc.), but the basic format is always XML/DocBook. Each document can be automatically converted into other formats for downloading. The history of modifications is kept in SVN, and any previous versions of a document can be recovered.
html2db.xsl converts an XHTML source document into a Docbook output document. It provides features for customizing the generation of the output, so that the output can be tuned by annotating the source, rather than hand-editing the output. This makes it useful in a processing pipeline where the source documents are maintained in HTML, although it can be used as a one-time conversion tool too.
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.
