Hi all,
First of all a big thank you to Hans for MkIV xml support which is so
much easier to understand than the MKII based method (or is that just
me?) Anyway, I'm processing a rather messy html file and I would like to
do some conditional processing based on the actual content of the
element. See example below: I have linked <h3> with \subject but I would
like to drop this element if the content of the element matches 'Skip
title'.
Any hints? Thanks!
Jelle
\startbuffer[test]
<html>
<h3>Title 1</h3>
<p>Hello world.</p>
<h3>Skip title</h3>
<p>Hello world!</p>
<h3>Title 2</h3>
<p>Hello world?</p>
<h3>Title 3</h3>
<p>Hello :-)</p>
</html>
\stopbuffer
\startxmlsetups xml:setups
\xmlsetsetup{main}{html|h3|p}{xml:*}
\stopxmlsetups
\xmlregistersetup{xml:setups}
\startxmlsetups xml:html
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:h3
\subject{\xmlflush{#1}} % but drop this if content of element is
'Skip Title'
\stopxmlsetups
\startxmlsetups xml:p
\xmlflush{#1}\par
\stopxmlsetups
\starttext
\xmlprocessbuffer{main}{test}{}
\stoptext
Expected outcome:
Title 1
Hello world.
Hello world!
Title 2
Hello world?
Title 3
Hello :-)

The next does not deserve a price for elegance, but because
\xmlflush is expandable (this is its best feature, I think!)
you can use the traditional tex toolkit macros:
\startxmlsetups xml:h3
\doifinstringelse{Skip title}{\xmlflush{#1}}
{}
{\subject{\xmlflush{#1}}}
\stopxmlsetups
I'm fairly certain that there are nicer solutions, however.
Best wishes,
Taco

Hm, and that should have been prize, not price.

Thanks Taco, this works, I owe you a beer at next year's ConTeXt
meeting! I'm still interested in a 'proper' xml (= non-TeX) based
solution, anyone?

\startxmlsetups xml:h3
\xmldoifnot {#1} {[text()='Skip title']} {
\subject{\xmlflush{#1}}
}
\stopxmlsetups
or:
\xmlsetsetup {main} {h3[text()='Skip title']} {-}
