This is Only a paragraph.

This is another paragraph.

\stopbuffer \startxmlsetups xml:initialize \xmlsetsetup{#1}{*}{-} \xmlsetsetup{#1} {html|body|div|p} {xml:flush} \xmlsetsetup{#1} {html/**/span[@class='special']} {xml:special} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:flush \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:special \bgroup\bfd\ssd\xmlflush{#1}\egroup \stopxmlsetups \starttext \xmlprocessbuffer{main}{demo}{} \stoptext How can I select only ? I mean, how can I have "Only" and nothing more in the output PDF document? I thought that lpath "html/**/span[@class='special']" would work, but I don’t know what I’m missing.

This was extremely handy and helpful (it is also the first time I understand what \xmlfilter is used for). My final solution required nesting filters, which worked perfectly fine (included below).
