When i run it, i see it fail w/ error message:

 sxml/sxml-match.ss:342:31: Throw to key `sxml-match-error'
 with args `(#f "bad pattern syntax (symbol not allowed
 in this context)" [...]

(output folded and truncated).  To my untrained eye, the form
looks similar to the examples in Info node ‘(guile) sxml-match’
but evidently i am missing something.  What?
