[xquery-talk] If Statements within an If Statement?

[Wei, Alice J.]

Hi, XQueriers:

   This may be a simple problem, but it appears that I have either missed something or have problems figuring out what a certain function means.

Here is my function:

declare function local:searchresult($seq as element()*) as element()*
{

let $a := collection("my")//ad//address[contains(upper-case(.),$search)],
$b := collection("my")//ad//p[contains(upper-case(.),$search)],
$c := collection("my")//ad//address[contains(upper-case(.),$search5)],
$d := collection("my")//ad//p[contains(upper-case(.),$search5)]

let $sorted_result:=
for $doc in distinct-values($seq)
order by $doc
return $doc
for $d at $count in $sorted_result
let $head := $seq[.=$d][1]/ancestor::ad//child::head[1]
let $head2 := $seq[.=$d][1]/ancestor::ad//child::head[2]
let $head3 := $seq[.=$d][1]/ancestor::ad//child::head[3]
let $para := $seq[.=$d][1]/ancestor::ad//child::p
order by $d
return
<div><p>Showing Result: <b>{$count} / {count($sorted_result)}</b></p>
<p style="font-weight:bold">{$head}&#160; {$head2}&#160; {$head3}</p>
<p>{$para}</p>
</div>
};
local:searchresult($a union $d

I would like to have this so that it can say something like

return

if (count($sorted_result) lt 1)
then <p>Sorry, no results retrieved.</p>
else if (count($sorted_result) gt 200)
then <p>Sorry, too many results returned.</p>
else
<div><p>Showing Result: <b>{$count} / {count($sorted_result)}</b></p>
<p style="font-weight:bold">{$head}&#160; {$head2}&#160; {$head3}</p>
<p>{$para}</p>
</div>

My problem is

(1) When I tried to do a count of the result in the first if statement, it does not even show anything. (Is this another XPath problem?)
(2) Is this syntax accurate?

Any suggestion is appreciated.
