If you meant: <root> <chapter><title>C1</title> <wrapper> <wrapper> <section><title>S1</title> </section> </wrapper> <section><title>S2</title> <section><title>S3</title> </section> </section> </wrapper> </chapter> </root> then //descendant::*[self::section][title][not(ancestor::*[self::section][title])] will give you the first titled element of the type you're looking for. You'll need to put the actual values for "foo" and "bar" in where there's a predicate for [self::section]; [self:foo or self::bar] -- Graydon
