New functions: XQuery 3.0 adds a number of functions, some previouslyĪvailable only in XSLT are now available in XQuery 3.0. See the article on the eXist-db blog, Switch Expression, and the specification.

This suite, which focuses on XQuery 1.0, contains more thanġ4,000 tests, and eXist-db passes more than 99.4% of the tests. The eXist-db XQuery implementation is tested against the official XML Query Test Suite An implementation ofĪrrays is in the works. From XQuery 3.1, the map data type is fully supported.
