'BRAND® XXL (sub brand text) EXACT TEXT' continued sentence text...

Where both 'XXL' and 'EXACT TEXT' are variable (and will always be used together; either they are both included or both excluded).

There's also another wrinkle to the problem that I just found out about, in that the first mention of each version on each page needs to be the full text. I don't believe that should be a problem as I can check each found set, and keep track of whether that version has been shortened for each page.
