Subject: [xsl] Lx: a compact syntax for XML/XSL From: Norman Gray <norman@xxxxxxxxxxxxxxx> Date: Sun, 18 Apr 2004 23:39:10 +0100 (BST) |
Greetings, I'd like to announce a first public release of lx: a compact syntax for XML, of particular interest for authors of XSL. Yeeees, another one. But wait: * it's not yet another `binary XML' proposal -- there's no need for that; * it's not intended to take over the world. Lx is intended to be useful for folk authoring that specific class of documents -- such as XSL stylesheets and RDF serialisations -- which have more markup than content. It's certainly my experience that editing XSL stylesheets is more unpleasant than it need be, because the structure is hard to see amid all the angle-brackets, end-tags, and endlessly repeated namespace prefixes. Dammit: XSL files just look so _ugly_! Perhaps this is not a problem for those who read and write XSL all their waking hours, and it's likely not a problem for those new to XSL, for whom the regularity of XML might arguably be a benefit. Lx is for those of us in the middle. Here, for example, is the XSL identity transformation in Lx: (lx:namespace ((#f "http://www.w3.org/1999/XSL/Transform")) (stylesheet version: 1.0 (template match: "node()|@*" (copy (apply-templates select: [@*|node()]))))) It looks lispish because that's a well-defined syntax, with good support in editors, which closely matches the structure and semantics of XML, and XSL in particular. It's not lisp, however. This release consists of the definition of the syntax plus a rather lightweight Java package that implements org.xml.sax.XMLReader. This parses the syntax and turns it into a SAX1 or SAX2 stream. It's GPLed. Further details, examples, javadocs, and downloads at <http://www.astro.gla.ac.uk/users/norman/distrib/lx/> All comments welcome.
