Just be aware that my solution gives you only the lexical content of the
tags, so that the tag [% FOO | html %] would be returned as "FOO | html",
not just "FOO".  And if you had a tag [% FOO; BAR; BAZ %], you'd get the
string "FOO; BAR; BAZ".  If you need to get at the actual semantics of the
document--for example, if you needed the three separate tags "FOO", "BAR",
and "BAZ" above--you'll need to roll your own code to get it, or find the
right place to hook into the existing framework.
