Ah, but dc:title does *not* have TEXT.  It has newline, many spaces,
TEXT, newline, many spaces.  Your regexp has a start ^ and end $ anchor,
meaning it matches if *all* of the content is only alphanumeric.  The
leading and trailing whitespace introduced by pretty-printing does not
match.

Either use strip-space in your parser (or XSLT, if in that context), or
match on sc if appropriate, or amend your regexp to allow leading and
trailing whitespace.
