vCard4J is a complete toolkit to manipulate vCards (RFC 2426) in Java. It contains a parser to read vCard files. It also includes a compiler to extend the library. vCard types are defined in a XML file, making it easy to add custom types. It also contains XSLTs to convert the internal DOM structure into vCards 3.0, xHTML, or other formats.
X2U (XML to user) is an XML editor that does not force users to read XML markup. Instead, users fill out simple Web forms, which are automatically derived from XML models. The XML model provides the XML structure and an interface. It accepts an XML document, an XML Schema, a DTD (Document Type Definition), or an XML form (XForms), and requires only a Web browser to use.
Lantern is a tool that lets users load XML documents and test XPath expressions. It produces an immediate graphical result where selected and context nodes are highlighted, and displays the XML document in the same format as it is stored in the file (rather than as an ugly tree widget). It is aware of name spaces and allows the user to set a context node to test expressions related to it.
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.
jSimpleX is a visual XSL transformation tool. It uses an XML (source) file and an XSL/XSLT (stylesheet) file to produce a new (output) document. The output can be in a variety of formats, such as XML or HTML. It provides a mechanism for loading, editing, and saving each of the three documents. It also provides a preview tab for XML and HTML (version 3.2) documents. It also supports a commandline mode and an Ant task for automated builds.
XPcm is a flexible PHP based content management framework which allows you to easily create and manage your websites. XML and XSLT are used for dynamic page creation and search-engine friendly content rendering. It features Workflows, task management, a WYSIWYG editor, user and group/role management with permission-inheritance, a media-database, module and plug-in support, flexible caching, and a fully browser-based back office.
