Hi.
I have the following piece of code:
----------------------
$hits :=
for $entries in collection($collctn)//tei.2
let $docname := concat($entries/@id, '.xml')
let $divs := $entries//div1
let $text := $entries/text
where contains($text, $keyword)
and $entries//classcode = $region
and $entries//classcode = $gender
and $entries//classcode = $race
and $entries/@type = $type
return
<doc>{$entries/@type, <ct>-</ct>}</doc>,
----------------------
and I need to make each 'and $entries...' statement conditional
(if the variable doesn't equal 'all' then it needs to be included,
otherwise, it needs to be left off).
I believe I need to use a concat() to do it, but I can't seem to get
the syntax right.
Should I put the entire hits variable into a concat()?
(if it matters, I'm using berkelydbxml for this)
Thanks,
Cindy
