If your list of document names is also in XML, e.g. <list> <doc>docname1.xml</doc> <doc>docname2.xml</doc> ... </list> you could use: let $doclist := document { <list> <doc>docname1.xml</doc> <doc>docname2.xml</doc> </list> } for $docname in $doclist/list/doc/text() intersect uri-collection("collection") let $doc := doc($docname) (: do something :) return concat("processing...",$docname) Perhaps you need to make sure that the document names are of type xs:anyURI instead of string, but I suppose you can figure that out :) Is that what you were thinking of?
