I clicked on the RSS feed on Tim Bray's web log, which serves it as application/rss+xml; and Mozilla tried to open it. That's funny. Shouldn't it display it? It is an XML file after all. I tried passing it to RSSOwl, but nothing happened.
The Apache Commons Team has released Digester 1.6, a SAX-based XML to object mapper, designed primarily for parsing XML configuration files though it has other uses too. Digester is configured through an XML to Java object mapping module, which triggers actions whenever a pattern of nested XML elements is recognized. Version 1.6 "includes many bug fixes and minor enhancements as well as several new features including plugins (framework supporting dynamic rule reconfiguration) and variable expansion."
Engage Interactive has updated two open source XML parsers written in PHP. SAXY 0.8.6 exposes a SAX like interface. DOMIT! 0.9.7 exposes an API based on the Document Object Model (DOM). Both are published under the GPL. These releases fix a bug in comment parsing.
Michael B. Allen's posted domc 0.8, an opens source implementation of the Document Object Model Level 1 (DOM1) in ANSI C. It depends on the the Expat XML Parser Toolkit. This is a bug fix release.
Jeff Key's posted a free-beer XmlDocViewer for Windows.
