Jeni,

Thanks!, a question from Eric's answer:

Is it file://b[preceding-sibling::*[1][self::a]]
or file://b[preceding-sibling::*[last()][self::a]]

Meanwhile for XML-SPY users you should use
Is it file://b[preceding-sibling::*[position()=1][self::a]]
Because
Is it file://b[preceding-sibling::*[1][self::a]]
doesn't work.

This is a XMLSPY bug isn't it?
