Answer 1

You need to use current():

current() gives you the context node as it is outside of the current XPath expression; in this case, the current element selected by xsl:apply-templates. Inside the predicate, the context node is the element that's being tested against the predicate expression.

Notes:

• You had a @ in there that you don't want; @ID refers to an ID attribute.
• I replaced descendant::/ with //
• As @Dimitre noted, your stylesheet will scale better to large input if you use keys instead of //foo[barID = current()/ID].
