Hi all,

I’m running out of time on this project I am working on and so I am hoping someone can help me again:

I’m trying to set an instance’s value to be the position of the choice node where special = true in my main instance.

The xpath expression to find that particular node is

instance(‘my-instance’)/setup[os=’windows’]/choices/choice[special=’true’].  Only one node per OS will have special=’true’.

Can someone please tell me the correct syntax to get the position of that node?  I’ve tried many combinations but none seem to work.   

Doing “string(count(../preceding-sibling::choice[special=’true’])+1)” doesn’t seem to work as there are multiple OSes in this setup and I need the one that is for windows specifically (in this case).

Thanks!

Stephanie
