Can you specifically show what you mean?
I did 😀

You just need to make it into a singleton query by plopping some brackets round the selector...
select a.b.value('[highlight="#ffff11"]([/highlight]PID[sql:variable("@LoopCount")]/PID.3[highlight="#ffff11"])[/highlight][1]', 'varchar(200)') as tehvalue2from @XMLDoc.nodes('HL7Message') as a(b)
To explain more, this:
PID[sql:variable("@LoopCount")]/PID.3[1]
is not a singleton query because (as far as the engine knows) there could be more than 1 PID that matches whatever is in the variable @LoopCount.
The fact you put "[1]" after the "PID.3" selector just means "the first PID.3 node which is a child of any PID node previously selected", so you need the brackets I have now [highlight="#ffff11"]highlighted [/highlight] (but were in my first response already) to make the xpath query into a singleton query.
Hope that explains a bit better for you 🙂
