A discussion on the saxon list recently reminded me that key() doesn't work unless the XML tree has a document root - this is per-spec (although Michael Kay argued that the spec authors may not have made the best decision on that aspect).
http://www.w3.org/TR/xslt20/#function-key [ERR XTDE1270] It is a non-recoverable dynamic error<http://www.w3.org/TR/xslt20/#dt-nonrec-dynamic-error> to call the key<http://www.w3.org/TR/xslt20/#function-key> function with two arguments if there is no context node<http://www.w3.org/TR/xslt20/#dt-context-node>, or if the root of the tree containing the context node is not a document node; or to call the function with three arguments if the root of the tree containing the node supplied in the third argument is not a document node.

Check out the usage notest for xslt-eval. While playing around I also got the impression that key() may need to be used in a document-rooted node. Anyway, try wrapping your data up as document { <persons> ... </persons> } That worked for me. - Chris On Fri, Mar 28, 2014 at 4:39 AM, Vijayasekar Padmanaban <[email protected]<mailto:[email protected]>> wrote: Hi, I am trying to transform xml using stylesheet in Marklogic 6.0-4 version.
