Hi all, I'm struggling with getting a working example of the following problem: I'm sending a query to an API that returns some data and, if the data set is large enough, a resumption token to requery the API.
I'm stuck at the point of how to generate the new query URL, while still processing the new data. Is the best idea to create a function that will update a new request to the API, or is there a different approach that can be used? I've made several attempts with functions -- the latest non-working examples are below -- and I'm missing... something, but I don't know what. Thanks for any guidance you can provide. Cheers, Bridger (: sample query :) (: http://server:8080/fedora/objects?query=pid~{$collection}*&resultFormat=xml&pid=true :) declare variable $query external := ' http://our.server:8080/fedora/objects?query=pid~gamble*&resultFormat=xml&pid=true '; declare variable $sessionToken := '&sessionToken='; declare variable $resToken := ''; (:functions:) (:doesn't work:) declare function local:getPID($in as document-node()) as xs:anyAtomicType* { data($in/*:resultList/*:objectFields/*:pid) }; (:doesn't work:) declare function local:reQuery( $in as document-node(), $rQ as xs:untypedAtomic*) as document-node() { let $rQ := $in/*:listSession/*:token/text() return ( if ($rQ) then local:getPID(doc("$in" || "&sessionToken=" || "$rQ")) else () ) }; (: this works processing the descendant elements but doesn't recurse :) for $result in fn:doc($query)/*:result let $resToken := $result/*:listSession/*:token/text() let $pid := $result/*:resultList/*:objectFields/*:pid/text() return ( $result, $resToken, $pid ) (: sample returned from query; e.g. $result :) <result xmlns="http://www.fedora.info/definitions/1/0/types/"; xmlns:types=" http://www.fedora.info/definitions/1/0/types/"; xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation=" http://www.fedora.info/definitions/1/0/types/ http://localhost:8080/fedora/schema/findObjects.xsd";> <listSession> <token>63c0762b5eb3d4b46c58add843b7b3e6</token> <cursor>0</cursor> <expirationDate>2016-01-18T01:40:05.381Z</expirationDate> </listSession> <resultList> <objectFields> <pid>gamble:1</pid> </objectFields> <objectFields> <pid>gamble:10</pid> </objectFields> </resultList> </result>
