Re: [xsl] using every inside a predicate

["andrew welch" <andrew.j.welch@xxxxxxxxx>]

The context node in the last predicate is <name> so its not doing
anything, you either need

every $s in /sections/section   (to make it from the root)

or

every $s in ancestor::sections/section  (to walk back up the tree)

depending on your real xml.
