You should use something like sxml-match.

  http://www.gnu.org/software/guile/docs/master/guile.html/sxml_002dmatch.html#sxml_002dmatch

  (sxml-match node
    ((img (@ (src ,src)))
     src))

A bit verbose for this particular example, but it's the best, most
robust way to parse out values from xml-in-s-expressions.
