I'm new to the list so I'll explain what I'm doing first: I'm working on a port of the Saxon XSLT and XQuery processor to the .NET platform using IKVMC. (You may already be familiar with this as Saxon.NET, but I'm now looking at folding it into the core product). I'm finding most things are working pretty well first time; the discrepancies I'm seeing in my test suite results are primarily: * numeric precision and formatting * URI handling * collation support * regular expressions (which is pretty much what I would have expected). The topic here is regular expressions, where I am seeing a lot of tests fail. Is there any information available as to the precise specification of the regular expressions supported by Gnu Classpath, and/or the differences from the Sun JRE? Saxon supports the regular expressions of XML Schema and XPath 2.0 by translating them into the regular expression dialect supported by Java (the translator to do this was originally developed by James Clark). It's quite possible that this produces some rather unusual regex patterns as a result. It's not the end of the world if the Gnu dialect is slightly different, because I can modify the translator to cope. But I do need to know what specification I am working to! Alternatively I can target the regex library on the .NET platform. Michael Kay http://www.saxonica.com/
