XQuery with if condition in for loop - xquery

Question

I have written xquery to return results in normal way.
let $results := //data:data
return
<result>
{
for $i in $results
return
<documentInformation>
<id>{data($i/DATA:ID)}</id>
<status>{data($i/#status)}</status>
<title>{data($i/data:title)}</title>
<displayName>{data($i/DATA:DISPLAYNAME)}</displayName>
</documentInformation>
}
</result>
Now, I have to filter out the results in for loop with some condition like
(pseudo logic)
if id = 'abc' and status ="closed"
then skip the row
else add row.
I have tried several ways. but could not run the query..

Answer 1

Try this:
<result>
{
for $i in //data:data
where fn:not($i/DATA:ID = 'abc' and $i/#status = "closed")
return
<documentInformation>
<id>{data($i/DATA:ID)}</id>
<status>{data($i/#status)}</status>
<title>{data($i/data:title)}</title>
<displayName>{data($i/DATA:DISPLAYNAME)}</displayName>
</documentInformation>
}
</result>
Note that the XPath //data:data may have a lot of work to do, but that's a separate matter.

Answer 2

You Can also use if condition instead of where
<result>
{
for $i in //data:data
return
if($i/DATA:ID != 'abc' and $i/#status != "closed")
then
(
<documentInformation>
<id>{data($i/DATA:ID)}</id>
<status>{data($i/#status)}</status>
<title>{data($i/data:title)}</title>
<displayName>{data($i/DATA:DISPLAYNAME)}</displayName>
</documentInformation>
)
else ()
}
</result>
