Helen,
Use:
cts:element-query( xs:QName("ns:mytag"), cts:and-query(()) )
The empty sequence passed to an and-query evaluates like "true."

Subject: [MarkLogic Dev General] question about cts:query
Hello there,
I think I sent this message to the wrong email last time, so I'm resending it.
I have a query like the following:
let $and-evq := cts:and-query((cts:element-value-query(fn:QName("ns","coden"),
"AA", ("case-insensitive")),
cts:element-value-query(fn:QName("ns","volume"),
"97", ("case-insensitive")),
cts:element-value-query(fn:QName("ns","issue"),
"1", ("case-insensitive"))),())
return
for $d in cts:search(fn:doc(), $and-evq)
return
fn:base-uri($d)
Now I need to add another query into $and-evq to say like: the element
fn:QName("ns","mytag") exists. I don't have the value for mytag to match, I
just want to make sure there is a element called "mytag" in the xml file. I
see a lot of APIs for value match, but not sure how I can check if an element
exists. Or is there any other ways to do it? This is for real time search.
I'm using marklogic 4.1.
Thanks, Helen
