question about an lpath

question about an lpath

[Pablo Rodriguez]

Dear list,

I have the following sample:

    \startbuffer[demo]
    <div class="super">
          <h1>Chapter</h1>
          <p>This is the only paragraph in red.</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>
    \stopbuffer

    \startxmlsetups xml:initialize
          \xmlsetsetup{#1}{*}{xml:*}
          \xmlsetsetup{#1}
            {div[contains(@class,'super')]/p[position()==1]}
            {xml:p:super}
    \stopxmlsetups

    \xmlregistersetup{xml:initialize}

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

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

    \startxmlsetups xml:p
          \xmlflush{#1}\par
    \stopxmlsetups

    \startxmlsetups xml:p:super
          \bgroup\red\xmlflush{#1}\egroup\par
    \stopxmlsetups

    \starttext

    \xmlprocessbuffer{main}{demo}{}

    \stoptext

Would it be possible to have another lpath for xml:p:super similar to
the following CSS selector? (Sorry, this is much easier for me.)

    div.super > h1 + p {}

After searching in xml-mkiv.pdf, I’m afraid I haven’t been able to find
which might be the lpath replacement for "+".

Many thanks for your help,


Pablo

maybe this?

{div[contains(@class,'super')]/h1/../p[position()==1]}
