Exactly what I thought, ABSML attacks the hard problems...poorly. I'm sure it's possible to run custom markup without errors, but that success is based on one's tenacity. The source code is <a href="http://code.google.com/p/absml/downloads/list">a zip file</a> of the web application at <a href="http://transition.turbulence.org/Works/absml/">Turbulance</a>. The parser is a bunch of PHP using regexs and string matching (re-inventing the wheel, perhaps?) and the user interface is a web page. Here's what I propose: <ul> <li> Use <a href="http://www.xml.com/pub/a/2005/11/09/rexml-processing-xml-in-ruby.html?page=2">REXML</a> to parse a document tree</li> <li>reimplement the classes as Rails controllers</li> <li>All the data can be kept in Rails models</li> <li>ActiveRecord can help pull stuff out of the database.</li> </ul> 2009-02-05T00:24:40Z 35 true 2009-02-05T00:25:53Z
