Passing a node to Xquery function

Question

Hi All,
I have two functions in my xquery. I'm trying to pass a node from one function to another function to check if it exists and do some processing on the text that is present in that node (if exists).
declare function appendLines($node as element()) as xs:string {
     if(fn:exists($node) and $node/text() ne "") then
          fn:concat($node/text(),", ")
     else (
appendLines($LINE_ITEM/ns0:STATXT)
Is the above call to that function is correct?
Thanks!!!

Answer 1

declare function appendLines($node as node()*) as xs:string {
          if(fn:exists($node)) then
               if(fn:string-length(fn:normalize-space($node/text())) > 0) then (     
                    fn:concat($node/text(), " ")
               else (
          else (
It worked with the above function.
