Hi Daniel,

What is the `/9` for in your expression? Is that a typo or where you trying
to do something with the number 9? Also in XPath, it's not `true` and
`false`, but `true()` and `false()`. I.e. those are functions, not keywords,
as is the case in many other languages. Finally, instead of `if (something)
then true() else false()`, you just write `something`.

You'll let me know if with this you manage to do what you were looking for.

‑Alex
