FunctX is an XQuery library with over 100 useful functions written by Priscilla Walmsley.
The source has been available for a while, but it was a little hard to use, as the code was separated for each function. Priscilla made now an XQuery module available for download.
Simply import the module in your query and be ready to use the functions.
The library has been tested with Saxon as well as DataDirect XQuery.
