RE:  How can I test the last preceding text character?
Replace

preceding-sibling::*[1]/text()[last()]

with

preceding-sibling::node()[1]

If the preceding sibling is an element node, you'll get its string value
automatically, you don't need to get it's text node children explicitly.

There's also an ends-with() function in 2.0 which might be clearer than
regular expressions for such a simple job.
