22302 2013-06-06 18:20:08 +0000 The equivalent code for fn:for-each() is incorrect. 2013-06-09 21:33:05 +0000 1 1 1 Unclassified XPath / XQuery / XSLT Functions and Operators 3.0 Working drafts PC Windows NT RESOLVED FIXED P2 minor --- 1 nbrinza mike public-qt-comments oldest_to_newest 88836 0 nbrinza 2013-06-06 18:20:08 +0000 In the current working draft of XQuery F&O 3.0, the fn:for-each() function ( http://www.w3.org/TR/xpath-functions-30/#func-for-each ) has the following equivalent XQuery code: declare function fn:for-each($seq, $f) { if (fn:empty($seq)) then () else $f(fn:head($seq)), fn:for-each(fn:tail($seq), $f) }; Probably the parenthesis around the else branch have been omitted, and so this code will result in an infinite recursion for any input. The fix would be to change the line: else $f(fn:head($seq)), fn:for-each(fn:tail($seq), $f) to: else ($f(fn:head($seq)), fn:for-each(fn:tail($seq), $f)) 88983 1 mike 2013-06-09 21:33:05 +0000 Thanks, I have deemed this editorial and have fixed it (by adding parentheses as suggested). There was also a typo in the XSLT version of the function (missing quotes).
