With XML similar to:
<a>
<b>
<c>1</c>
<c>2</c>
<c>3</c>
</b>
I'm trying to create an xpath expression (for a postgresql query) that will return if is a particular value and not that is all three values.
What I currently have (which does not work) is:
select * from someTable where xpath ('//uim:a/text()', job, ARRAY[ ARRAY['uim','http://www.cmpy.com/uim'] ])::text[] IN (ARRAY['1','3']);
If I try with ARRAY['1'] this will not return any values but with ARRAY['1','2','3'] it will return all three.
How can I select based on a single element in a sequence?
Thanks.
