Unique value with Xquery and SoapUI

Question

First of all, Sorry if I do mistake in my question. I'm french and not the best in english. I have a problem with a Xquery Match in Soapui. There is an exemple of a Soapui response:

<ns0:Group>
     <ns0:Personne>
        <ns0:idPersonne>111</ns0:idPersonne>
     </ns0:Personne>
     <ns0:Personne>
        <ns0:idPersonne>222</ns0:idPersonne>
     </ns0:Personne>
     <ns0:Personne>
        <ns0:idPersonne>333</ns0:idPersonne>
     </ns0:Personne>
</ns0:Group>

I need to check if the Id of a personne is unique or not. If "111" appears only once, it returns "true" If not, it returns "false". Could you help me?

This should do the trick for you:

count(distinct-values(//ns0:idPersonne)) eq 1

I am not that familiar with Soap UI though, so if you have trouble with namespaces you might also like to try instead:

count(distinct-values(//*:idPersonne)) eq 1
