\xmlfilter is your friend:

 \startxmlsetups xml:initialize
   \xmlsetsetup{#1}{html}{xml:gen}
 \stopxmlsetups

 \xmlregistersetup{xml:initialize}

\startxmlsetups xml:gen
    \xmlfilter{#1}{/**/span[@class='special']/command(xml:special)}
\stopxmlsetups
    
 \startxmlsetups xml:special
   \bgroup\bfd\ssd\xmlflush{#1}\egroup
 \stopxmlsetups


Best wishes,
Taco
