How to select unique nodes

Question

I found this page describing the Muenchian method, but I think I\'m applying it wrong.

Consider that this would return a set of ages:

/doc/class/pers         


        

Answer 1

For those who still look for a select distinct in XSLT:

With XSLT 2.0, you can use "distinct-values(/doc/class/person/descriptive[(@name='age')]/value)"
