I have the following
url : &author=TOM
I have xqy function that places this into an element params.
let $params := <params><author>TOM</author></params>
I use this variable as such
let $a := if (fn:boolean($params/author/text())) then $params/author/text()
else ""
return myfunc:hi($a)
The above variable is tested because of the following:
define function myfunc:hi($a as xs:string)
This will through exception if $a is empty.
Would this be considered good practice/best practice.
I have other ideas:
myfunc:hi($as as xs:string?)
and alter function if needed
create new function
myfunc:init-params($params as element(params))
and initialize all variables here
thoughts, experience, caveats ?
/text()
empty variable
strings
etc...
