Hamilcar is an XML application server inspired by Apache Cocoon for Objective Caml, using the Yaxi library. It is designed around the concept of a pipeline that is traversed during the processing of a request with control structures embedded in XML tags directing the process according to various criteria.
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.
Xmldiff is a Python tool that finds the differences between two similar XML files in the same way the diff utility does for text files. A description of the changes found can be displayed using Xmldiff's syntax or as an XUpdate script that can be used to "patch" the original document.
NekoStyle is a simple and flexible framework for automating XML transformations. With NekoStyle, you can parse XML and HTML documents, perform XSLT transformations, output documents in different formats, and much more. An Ant build task is also included to allow batch XML processing to be run during a build.
Fast Parser is a high performance Java XML parser. Benchmarks measure it to be up to 100%+ faster than Xerces and the JDK1.4 integrated parser. It is ideal for Web services (SOAP) and XSL. The core parsing package (without DOM) is very compact. It features SAX Level 1 and 2 compliance, JAXP compatibility, namespace support, integration with JXMLPad for real time parsing, modular libraries, an embedded device mode (including minimal memory usage), optional XML Comment support, CDATA support, the ability to include any node type with a custom NodeFactory, and a walker for easily navigating through XML trees. Many API samples and benchmark tests are included. JDK1.1 or later is required.
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.
