Re: [xsl] xslt regex exclude string from variable used

Oh, yes, silly me - that was nonsense.

But the "negative-look-ahead" triggered a completely wrong line of
thought - and I don't think you can avoid matching the given
expression E by any addition using negative look-ahead.

But you can modify the string represented by &journal_abbrevs; by
deleting the "example1" substring and one '|'.
