he goal of XMLVM is to offer a flexible and extensible cross-compiler toolchain. Instead of cross-compiling on a source code level, XMLVM cross-compiles byte code instructions from Sun Microsystem's virtual machine and Microsoft's Common Language Runtime. The benefit of this approach is that byte code instructions are easier to cross-compile and the difficult parsing of a high-level programming language is left to a regular compiler. In XMLVM, byte code-based programs are represented as XML documents. This allows manipulation and translation of XMLVM-based programs using advanced XML technologies such as XSLT, XQuery, and XPath.
For those of you who've got into it you'll know that test driven development is great. It gives you the confidence to change code safe in the knowledge that if something breaks you'll know about it. Except for those bits you don't know how to test. Until now XML has been one of them. Oh sure you can use "<stuff></stuff>".equals("<stuff></stuff>"); but is that really gonna work when some joker decides to output a <stuff/>? -- damned right it's not ;-)
CSSToXSLFO is a utility which can convert an XML document, together with a CSS2 style sheet, into an XSL-FO document, which can then be converted into PDF, PostScript, etc. with an XSL-FO-processor. It has special support for the XHTML vocabulary, because that is the most obvious language it would be used for. The tool has a number of page-related extensions. It also comes with an API in the form of an XML filter.
XPath Explorer (XPE) is a GUI application that lets you interactively experiment with XPath. Basically, you type in a URL (to an XML or HTML document) and an XPath expression, and it displays the elements or attributes from that document which match that
The OpenLaszlo platform allows developers to create applications with the rich user interface capabilities of desktop client software and the instantaneous no-download Web deployment of HTML.
