Hmm... Are the 'DC' pieces always the last pieces in the string? If
so, then you could take the substring after the first DC element,
strip out everything that isn't an = sign, and count how long a string
you have left:

  string-length(translate(
                  substring-after($string, 'DC'),
                  translate($string, '=', ''),
                  ''))

Otherwise, I think that what you're trying to do is of sufficient
complexity that a two-step transformation might be worthwhile. Use one
step to get the XML into a "groupable" structure, stripping out
information that isn't actually needed at the same time, and the
second step to create the groups from the data.

Cheers,

Jeni
