but meant:

<xsl:sort
select="translate(concat(.,self::*[contains(.,'-')]
                                              ^^^
/following::word[@type='end']), '-', '')" />

Brilliantly insightful solution.

Just to explain why the stuff I wrote used lots of substring() and
string-length() all over the place: I was assuming that there might be
words that contained hyphens in the middle of them.  For example:

  <word>ABC-</word>
  <word>spirit-level</word>
  <word type="end">DEF</word>

should presumably be output/sorted as:

  ABCDEF
  spirit-level

rather than:

  ABCDEF
  spiritDEF

Of course it might not be a problem with the input that you're using,
but if it is, then you need to substitute:

  contains(., '-')      -> substring(., string-length()) = '-'
  string-before(., '-') -> substring(., 1, string-length() - 1)

and of course using the translate() function will get rid of *all* the
hyphens in the words, which may or may not be helpful. The safest
solution is probably:

concat(substring(., 1, string-length() - 1),
       substring(self::node()[substring(., string-length()) != '-'],
                 string-length()),
       self::node()[substring(., string-length()) = '-']
          /following::word[@type = 'end'])

But of course you should use the simplest that you can get away with.

I hope that helps,

Jeni
