Mike, This is moderately efficient, so may work depending on your use case and the number of matching uris:
declare namespace functx = "http://www.functx.com";; declare function functx:substring-before-last-fslash($arg as xs:string?) as xs:string? { let $dir := replace($arg, '^(.*)/.*', '$1') return if (ends-with($dir, "/")) then $dir else () (: if there is no / at all, the replace will have no effect, so check the terminating slash to ensure it is a directory :) } ; let $q := ... some query ... distinct-values(cts:uris("", (), $q) ! functx:substring-before-last-fslash(.)) Note the "!" operator is a shorthand for a for loop in ML 6. Note the function is based on functx, but has the "/" delimiter hard-coded.

Is there an efficient way to retrieve all the directories containing the documents matching a query, in the way that cts:words does for words? -Mike _______________________________________________ General mailing list [email protected] http://developer.marklogic.com/mailman/listinfo/general _______________________________________________ General mailing list [email protected] http://developer.marklogic.com/mailman/listinfo/general
