Compiling XSLT 2.0 into XQuery 1.0 (2005)
Achille Fokoue, Kristoffer Rose, Jerome Simeon, Jérôme Siméon, Lionel Villard
As XQuery is gathering momentum as the standard query language for XML, there is a growing interest in using it as an integral part of the XML application development infrastructure. In that context,...
Optimizing sorting and duplicate elimination in XQuery path expressions (2005)
Mary Fernández, Jan Hidders, Jérôme Siméon, Roel Vercammen
Abstract. XQuery expressions can manipulate two kinds of order: document order and sequence order. While the user can impose or observe the order of items within a sequence, the results of path...
Automata for Avoiding Unnecessary Ordering Operations in XPath Implementations (2004)
