Xalan is an XSLT processor for transforming XML documents into HTML, text, or other XML document types. It implements the W3C Recommendations for XSL Transformations (XSLT) and the XML Path Language (XPath). It can be used from the command line, in an applet or a servlet, or as a module in other program. Xalan-Java version 2 recasts Xalan as an implementation of the TRaX (Transformation API for XML) interfaces, part of the Java API for XML Processing 1.1 Public Review 2. TRaX provides a modular framework and a standard API for performing XML transformations, and it utilizes system properties to determine which Transformer and which XML parser to use. Xalan-Java version 2 also builds on SAX 2, DOM level 2, and the XML parser API in Java API for XML Parsing 1.0.
