I've been looking around for implementations of XML Schema and XPath 2.0 so that I can test some things out for a research project I'm working on. Essentially I need to be able to specify a schema in XSD, create an XML document (or two or three) that conform to that schema and then I need to be able to run a series of XPath 2.0 expressions on those XML documents. An implementation that works in Java or Python is cool, but at this point I'd even be willing to learn a new language to get something working.
In Java-land, the only XPath 2.0 implementation I can find is SAXON. However, the "free" version, SAXON-B, isn't "schema-aware" (i.e. it doesn't have XML Schema handling in it). The site says I can get an evaluation license... but I'm not really interested in evaluating SAXON--I just want to run some tests to make sure my paper is accurate.
JAXB has an implementation of XML Schema. JAXP 1.3 is in Java 1.5, JAXP 1.4 is in Java 1.6. Both JAXP 1.3 and 1.4 have an implementation of XPath 1.0, but not 2.0 (which makes sense given that XPath 2.0 is pretty recent).
Jaxen supports XPath 1.0, but not XPath 2.0.
I can't find anything else in Java-land.
In Python-land, there's 4suite which has XPath 1.0 support, but doesn't seem to know anything about XML Schema.
There's also Amara, but given the documentation talks about "node sets", I suspect it only implements XPath 1.0. That's all I could find in Python-land.
My research is probably spotty. I'm relying upon Google searches and what I can garner from 20 minutes of skimming the project web-sites. I've also been using some loose heuristics to disambiguificate 1 usages of "XPath" with no version number--when someone refers to "XPath" or mentions "node-sets", I assume they're probably talking about XPath 1.0.
Anyhow, any ideas on XPath 2.0 implementations that I missed?
This is a word we used at ByAllAccounts often because it was amusing. There are other variations, too, such as disambiguificationalize. This sort of word bastardization makes documentation more interesting.
