The XML_XPath PEAR Class allows easy manipulation, maneuvering, and querying of a domxml tree using both xpath queries and DOM walk functions. It uses an internal pointer for all methods on which the action is performed. Results from an xpath query are returned as an XML_XPath_Result object, which contains all the DOM functions from the main object. This class tries to stay as close as possible to the DOM Recommendation. It is important to note that this is only an interface for the PHP domxml library. It depends on that library available (--with-dom) and hence requires PHP 4.2.1. This class is useful if you are looking for a fast implementation to XML documents.
Dragon Breath is the name of a generic development and application framework that is heavily based on PostgreSQL and PHP. It contains different layers which wrap business logic, data, and any graphical interface. It opens up and eases development in the field of graphical user interfaces and data management. The interface layer is built upon XSLT rendering, which allows the rendering of displays for different interfaces like Web browsers, PDAs, mobile phones, and others. The database layer depends on PostgreSQL's features and allows a common exchange of data with any kind of data structure. It even contains built in sanity checks for data integrity.
The goal of XPS is to make programming simpler by raising the level of abstraction without loss of performance. It provides true support for meta-programming and domain specific languages, making it possible to design simple programming languages to match the problem at hand. This is the opposite of current practice which seeks to translate the problem domain down into the low level solution domain of current programming languages.
The IEC 61131-3 Structured Text to XML Compiler parses an IEC Structured Text source and generates an XML representation of the syntax tree of the source. Names defined in the IEC 61131-3 grammar are used as tag names, though underscore characters in the names of the non-terminal symbols are replaced with a minus sign. The result then can be further processed with the YML toolchain or with an XSLT stylesheet. The compiler is compatible with the 61131-3 ST standard as used in the Beremiz project, as well as with the dialect of EPAS 4.
IrrXML is a high speed and easy-to-use XML parser without external dependencies. It is very small and provides forward- only, read-only access to a stream of non-validated XML data through an extensible object oriented interface. It ideally fits into realtime projects which need to read XML data without overhead, like games.
RenderX XEP is a commercial-grade application written in Java for dynamic rendering of XML documents. XEP is a pluggable architectural component that takes two open standard inputs, XML data and XSL FO stylesheet, and produces the industry's defacto standards for high-quality rendered electronic documents, Adobe PDF and PostScript. XEP supports many extensions to the XSL FO specification, including SVG graphics and PDF-to-PDF linking.
