bug when dealing with XML classes?

bug when dealing with XML classes?

[Pablo Rodriguez]

Hans,

I have the following sample:

\setupbodyfont[30pt]
\startbuffer[demo]
<doc>
    <h1>This is my title</h1>

    <div class="section" class="level1" class="hidden">
        <h1>This title is hidden</h1>
    </div>

    <div class="section level1 hidden">
        <h1>This title is not hidden</h1>

        <p>Text</p>
    </div>
</doc>
\stopbuffer

\starttext

\startxmlsetups xml:initialize
     \xmlsetsetup{#1}{div}{xml:div}
     \xmlsetsetup{#1}{h1}{xml:h1}
     \xmlsetsetup{\xmldocument}{[@id='epigraph']}{xml:epigraph}
     \xmlsetsetup{#1}{[@class='hidden']/h1}{}
\stopxmlsetups

\xmlregistersetup{xml:initialize}

\startxmlsetups xml:div
    \xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:h1
    \section{\xmlflush{#1}}
\stopxmlsetups

\xmlprocessbuffer{main}{demo}{}
\stoptext

ConTeXt MkIV is not able to understand

    class="section level1 hidden"

as

    class="section" class="level1" class="hidden"

and the second attribution is invalid XML (according to the W3C
Validator [http://validator.w3.org/] and xmlvalidation.com): class
should be only specified once.

I think this might be a bug in ConTeXt.

Many thanks for your help,


Pablo

It has nothing to do with understanding: successive attributes with the 
same name will overload a previous one. You can try this:

      \xmlsetsetup{#1}{[contains(@class,'hidden')]/h1}{}

it says: the markup validity of Web documents in HTML, XHTML, SMIL, 
MathML, etc.

we parse xml, and not html (some evolving dialect) ... in fact i think 
that the last class will win so that boils down to using only one

Many thanks for your fast reply, Hans.

I was totally wrong. It was my understanding the one that was buggy :-).

Many thanks for your help again,
