XML Query Languages

[konmpek]

I have my final project in my university,and i have to find and compare all the
xml query languages.I have focused until now at Lorel, XML-QL, XQL, XML-GL ,
XQuery and XSLT.
Are there any other languages to search?
Does the most of these language (like xml-ql,xql and xml-gl) work nowadays?
XDuce is also a usable language?
Thank you,
kostas

XSLT and XQuery are in very active use, and are very widely implemented.
XQL is a precursor to XPath, and the inventors of XQL and XML-QL put
their later efforts into XQuery, which is the language they now endorse.
I don't know how active Lorel or XML-GL are.

Also of interest are extensions to existing languages to support various
subsets of XQuery, such as Microsoft's LINQ and IBM's XJ.

XML-GL is currently evolved in XQBE (XQuery By Example).

Interesting is also XDuce which is a typed functional programming
language that is specifically designed for processing XML data.

Don't forget CQL, "Contextual Query Language".
http://www.loc.gov/standards/sru/cql/index.html

(It's "Common Query Language" in version 1.1 but renamed "contextual" in
1.2, a preview of which is available at:
http://www.loc.gov:8081/standards/sru/specs/cql.html)

Maurice,

If you're going to mention XDuce, we should also mention CDuce and OCamlDuce.

Best wishes,
