The XNGR XML Browser is an XML browser framework, written in Java, that provides the functionality to associate Markers with directories, files, XML documents, and nodes in an XML document. Services and Actions can be associated to inspect and manage these marked items. Default services include a simple XML Editor and XML Viewer.
Sablotron is an XML toolkit which implements XSLT, DOM, and XPath. Sablotron is written in C++, and it can be used from C, Perl, Python, PHP, ObjectPascal, and via a command line interface. It supports the XSLT 1.0, XPath 1.0, and DOM Level 2 W3C specifications. It is designed to be as compact and portable as possible, and is maintained as an Open Source project by Ginger Alliance.
Presenting XML is a Java Web application framework for presenting HTML, PDF, WML, etc. in a device independent manner. It supports various kinds of content, including XML files, dynamic content, SQL result sets, and flat files. It provides a declarative way for applying filters and XSLT transforms to a stream of XML content in a pipeline. It allows user defined filters and serializers written as Java plug-ins. It is component based and extendable. Presenting XML may be used as a command line tool or as a framework for a servlet-based Web application.
Xml Validation Interoperability Framework (xvif) is a proposal to embed pipe definitions in grammar based schema languages such as Relax NG (and probably W3C XML Schema). The current implementation is built on a partial implementation of Relax NG, supporting the features needed to provide a representative proof of concept. It is available both as Python source code and as an online demonstration. Although there is no endorsement of any kind by the DSDL ISO initiative (http://dsdl.org), one of the goals of this prototype is to gather feedback which may be used (or not) by "DSDL Part 1 - Interoperability Framework".
