XSLT syntax highlighting is an implementation of syntax highlighting as an extension module for Java based XSLT processors (such as Xalan or Saxon). For example, if you have an article about programming written in DocBook, code examples can be automatically syntax highlighted during the XSLT processing phase.
adx is a minimalistic but massively Web-enabled address book that runs completely in your Web browser. It's OS-independent and supports comprehensive details for each contact entry, including user identifiers and profiles for Skype, Twitter, Flickr, Delicious, Facebook, LinkedIn, studiVZ, instant messengers, etc. It supports the hCard and XFN microformats.
c_xml is a class that can convert between XML files and arrays or strings. It can parse an XML file into a DOM document object, so it can be returned as an array or displayed using a XSL stylesheet. The parsed XML document can also be manipulated to add, change, or remove nodes. Nodes may be searched using XPath. The resulting document can be regenerated in XML format.
Docbook2odf consists of DocBook XSLT stylesheets and utilities for converting DocBook into OpenDocument. It is not restricted to text-like documents and can generate presentations, charts, or forms with images and multimedia. The result is returned in a zipped ODF file (.odt/.odp/.ods) with all required content.
