The regular expression '|<sup 
class="gt_article_footnote">([^</sup>]+)</sup>|'

Says

"match the literal text '<sup class="gt_article_footnote">' then one or 
more characters that aren't <, /, s, u, p, or >, then the literal text 
'</sup>'"

You want

{<sup class="gt_article_footnote">(.+?)</sup>}

which says "match the literal text '<sup class="gt_article_footnote">' 
then as few characters as possible, then the literal text '</sup>'

(I also changed the delimiters to curly braces to avoid confusion with 
the | regex metacharacter.)

This regex still puts the stuff inside the <sup></sup> tags in $matches[1].
