Hi,
My exact requirement is such that I need t pass multiple ID's from XCC.Net API
ID values are comma separated like 123,456,789,1234,2345
Now if I pass this from XCC to xqyery module as string it would be like
"123,456,789,1234,2345"
My module code:
declare variable $ID as xs:string? as external;
let $tokens := fn:tokenize($ID, ",")
let $count := fn:count("$tokens")
for $token at $index in $tokens
let $args := fn:concat('"',$token,'"',",")
return
$args
I get my results as:
"123",
"456",
"789",
"1234",
"2345",
Now I have two questions:
1. How to remove the last comma?
2. Is $args is of type string array? If not then how to convert $args to an
string array.
Like this $args as xs:string* := ("123","456","789","1234","2345").
I need to use $args in the below query.
for $x in cts:search(doc("/temp.xml")//list/body,
cts:element-attribute-word-query(
xs:QName("title "), xs:QName("id"),$args),"score-simple", 1.0)
Thanks,
Pragya

That is actually what worked for us. We had to also allow for spaces in all
ingested files by concatenating an underscore to any file with a space or weird
character.

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 ''];

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

Probably an easy question but, is there a way to get the string value of a
declared namespace?
For example:
??? declare namespace foo = "http://www.foo.com";
??? <namespace_str>{ foo }</namespace_str>
I suppose I could always declare a variable with its value set as
"http://www.foo.com"; ...but I'd rather not since then there would be 2 places
where to keep track of the same value
thanks,

Hi,
The following should work:
declare namespace foo = "http://www.foo.com";;
<namespace>{fn:namespace-uri(<foo:bar/>)}</namespace>
