Dear list,
I have the following sample:
\startbuffer[demo]
<html>
<body>
<div class="irrelevant">
<p>This is <span class="special">Only</span> a paragraph.</p>
<p>This is another paragraph.</p>
<p>This is another paragraph.</p>
<p>This is another paragraph.</p>
<p>This is another paragraph.</p>
</div>
</body>
</html>
\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 <span class="special">? 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.
Many thanks for your help,
Pablo

\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

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>
</html>
\stopbuffer
\startxmlsetups xml:initialize
\xmlsetsetup{#1}{html}{xml:gen}
\stopxmlsetups
\xmlregistersetup{xml:initialize}
\startxmlsetups xml:gen
\xmlfilter{#1}{/**/div/command(xml:chapter)}
\stopxmlsetups
\startxmlsetups xml:chapter
\startsection[title=\xmlatt{#1}{id}]
\startitemize[packed]
\xmlfilter{#1}{**/span[@class='special']/command(xml:special)}
\stopitemize
\stopsection
\stopxmlsetups
\startxmlsetups xml:special
\startitem\xmlflush{#1}\stopitem
\stopxmlsetups
