Re: [NTG-context] reading a single element from XML

16 Aug 2020


      \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

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
