This is the confusing part. What do you mean by "return"?
An XPath expression matches nodes. You could have an expression that
matches the brands, or, lines, or items, or all of them, but it's not clear
what the value of matching all of them would be.
Now, if by "return" you mean "copy into the result tree", i.e. copy the
source tree but prune any branches that don't have offers, then what you
probably want to do is have a template that matches any BRAND with an offer
on any descendant, and then only process the ITEMs with any offers, etc.
<xsl:template match="BRAND[@OFFER]" priority="1">
