In the code below I encounter the problem, that I have to define the same xPath
function variable $organizations twice and I do not understand why.
In line 10, you've used a let clause to bind a variable of type function to the
name organizations. That's in context a specific FLOWR expression.
The expression in the return clause of that FLOWR expression returns an
element constructor where the contents expression contains another FLOWR
expression. The first definition on line 10 will be out of scope in
there.
I don't think so, the variable is not out of scope, it is bound for each
item in the group to that function, meaning that value in the return
clause of the group is a sequence of functions and that way
head($organizations)($country)
would work.
You could define the function with scope for the module:
declare function local:getOrganizations($in as element(country))
as xs:string* {
let $thisCountry as xs:string := $in/@id/string();
return $doc//organization[members/@country = $thisCountry]/@abbrev/string(.)
};
That is certainly the cleaner way.
