Hello list,
I need a lpath expression to intercept the first p (HTML paragraph)
after a p of class "incipit". Here's a (not) working example:
\startbuffer[test]
<text>
<p class="incipit">Dear list,</p>
<p>this paragraph should not be indented, because it follows the “incipit”
of the letter.</p>
<p>This one and the following ones should be indented.</p>
<p>You may question whether “Dear list,” should be a paragraph of his own,
but my text is already formatted like that and I can’t do anything
about it.</p>
</text>
\stopbuffer
\startxmlsetups xml:somesetups
\xmlsetsetup{#1}{text}{xml:text}
\xmlsetsetup{#1}{p}{xml:p}
\xmlsetsetup{#1}{p[@class='incipit']}{xml:p:noindent}
% the following lpath expression does not work
\xmlsetsetup{#1}{p[./preceding-sibling::[-1][@class = 'incipit']]}{xml:p:noindent}
\stopxmlsetups
\xmlregistersetup{xml:somesetups}
\startxmlsetups xml:text
\indenting[{yes,first,12pt}]
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:p
\xmlflush{#1}\par
\stopxmlsetups
\startxmlsetups xml:p:noindent
\noindent\xmlflush{#1}\par
\stopxmlsetups
\starttext
\xmlprocessbuffer{main}{test}{}
\stoptext
Thanks for any help.

I've found a better solution:
\startxmlsetups xml:p
\doif{\xmlattribute{#1}{reverse-sibling::p[1]}{class}}{incipit}{\noindent}%
\xmlflush{#1}\par
\stopxmlsetups
Still I did not manage to put that rule in a xmlsetsetup.
Tried this:
\xmlsetsetup{#1}{p[reverse-sibling::p[1]/attribute('class') == 'incipit']}{xml:p:noindent}
but it does not work.

I'm not sure if the "sibling" part of xpath syntax has been integrated
into context. The best I can come up with is a hack which may help:
\startbuffer[test]
<text>
<p class="incipit">Dear list,</p>
<p>this paragraph should not be indented, because it follows the
“incipit”
of the letter.</p>
<p>This one and the following ones should be indented.</p>
<p>You may question whether “Dear list,” should be a paragraph of his
own,
but my text is already formatted like that and I can’t do anything

</text>
\stopbuffer
\startxmlsetups xml:somesetups
\xmlsetsetup{#1}{text}{xml:text}
\xmlsetsetup{#1}{p}{xml:p}
\stopxmlsetups
\xmlregistersetup{xml:somesetups}
\startxmlsetups xml:text
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:p
\doifelse {\xmlatt {#1} {class}} {incipit}
{\noindentation \xmlflush {#1}\par \noindentation}
{\xmlflush {#1}\par \indentation}
\stopxmlsetups
\starttext
\setupindenting [medium, yes]
\xmlprocessbuffer{main}{test}{}
\stoptext
This will suppress indentation for paragraphs with class "incipit" and
the following paragraph.

Thank you for your answer, Thomas.
I tried something similar (putting a \noindentation at the end of the
"incipit" paragraph, but it failed if I put a \blank after that).
The sibling part
In the book of the history of luatex (v 0.50) it is said that the
sibling functions would not be implemented soon, but at least 3 methods
have been implemented. From the release notes 8/5/2010 (http://wiki.con
textgarden.net/Context_2010.05.08):
"implement following-sibling(), preceding-sibling() and reverse-
sibling() lpath methods"
If you search for "sibling" in the mailing list archive, you find a
pair of threads. I've found no other documentation.
"reverse-sibling" is ConTeXt specific and very useful: it's a "reversed
preceding-sibling", so that you find the nearest sibling at index [1].
I've used it successfully in a \doif statement, but I failed in
translating it in a \xmlsetsetup statement, to tell ConTeXt: "this
setup is for an element p whose nearest preceding sibling p has class
'incipit'".

Here's the (complete) code:
\startbuffer[test]
<text>
<p class="incipit">Dear list,</p>
<p class="dopo-incipit">this paragraph should not be indented, because it follows the “incipit”

% the following lpath expression does not work

\stoptext
It's the example of the original message of this thread, with the
modifications posted in the second message.
In the \startxmlsetups section I tried to put that condition in a
\xmlsetsetup, but I commented it out because it did not work.
Here's where I found an example with reverse-sibling:
https://www.mail-archive.com/ntg-context%40ntg.nl/msg77364.html
I was searching for "sibling" in the mailing list archive to see whether
"sibling expressions" had been implemented.
