This will work well if the values are simplistic. But if the values are arbitrary strings (which might contain commas, quotes etc) tokenize is problematic.
Another option is to create an XML file "As a string" then send it as an xs:string and use xdmp:unquote() to turn it into XML .

My suggestion is that you pass the sequence as a delimited string and then split that into a sequence inside the module using fn:tokenize: declare variable $collections-string as xs:string? external; declare variable $collections as xs:string* := tokenize($collections-string, ',')[. ne '']; From: [email protected] [mailto:[email protected]] On Behalf Of Lee, David Sent: Wednesday, May 26, 2010 8:09 AM To: General Mark Logic Developer Discussion Subject: Re: [MarkLogic Dev General] How to pass String Array to Marklogic usingXCC.Net API? The short answer is "no". You cant pass sequences, elements, documents or anything but atomic single value to XCC as external variables. I consider this a major "bug" but it is what it is. The long answer. 1) Wrap the sequence into a document, store the document in a temporary directory on the ML server, then do an ad-hoc query to parse the document, generate the sequence and call your module. Pseudo-code Client: create doc <doc><elem>a</elem><elem>b</elem> .... store doc in /temp/values.xml --- MAKE SURE THIS IS UNIQUELY NAMED (not always easy) call Ad-hoc query let $seq := doc("/temp/values.xml") return myprefix:myfun( for $e in $seq//elem return $e/string() ) 2) Dynamically create an ad-hoc query in xquery with the sequence as part of the code Client C# (ish) String query = "declare variable $args :-= (" ; for( value in values ...) query = query + "\"" + value + "\"," ; query = query + "())"; // hack to avoid figuring out what the last item was ... I'm lazy query = query + "myprefix:myfunc( $args) "; Call Ad-hoc query $query Feature Request to MarkLogic PLEASE add support for sequences and nodes to XCC variables !!!!

Hi, How to pass String Array to Marklogic using XCC.Net API. Marklogic is expecting data in the form of string Array in a query, I want to pass the data in A string array as {"a","b","c","d"} . I am not able to find the way to pass it to ML using C#. Is there any way to do it? Thanks, Pragya
