Many thanks for your reply, Taco.
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).
Many thanks for your help,
Pablo
Just for the record:
\startbuffer[demo]
<html>
<body>
<div id="First">
<p>This is
<span class="special">One</span> a paragraph.</p>
<p>This is another paragraph.</p>
<p>This is another
<span class="special">Two</span> paragraph.</p>
<p>This is another
<span class="special">Three</span> paragraph.</p>
<p>This is another
<span class="special">Four</span> paragraph.</p>
</div>
<div id="Second">
<p>This is
<span class="special">A</span> a paragraph.</p>
<p>This is another paragraph.</p>
<p>This is another
<span class="special">B</span> paragraph.</p>
<p>This is another
<span class="special">C</span> paragraph.</p>
<p>This is another
<span class="special">D</span> paragraph.</p>
</div>
</body>
