problem with interaction and TOC

problem with interaction and TOC

[Pablo Rodriguez]

Dear list,

I have the following sample:

    \setupinteraction[state=start]
    \starttext
    \placelist[chapter]
    %~ \uppercasestring{context}\to\ascii
    %~ \chapter{\getvalue{\ascii}}
    \chapter{ConTeXt}
    \stoptext

ConTeXt complains about an error in the first line.

What am I doing wrong? (Sorry, but I wanted to test the commented lines,
but I don’t know why the simplified example doesn’t work.)

Many thanks for your help,


Pablo

\uppercasestring{context}\to\ascii
\chapter{\meaning\ascii}  % \getvalue{\ascii}}
\chapter{\WORD{ConTeXt}}

so, \ascii is made undefined at some time

Many thanks for your reply, Hans.

I’m afraid that my ignorance prevents me for understanding your reply.

What I was trying to solve was this:

    \startbuffer[demo]
    <doc>
        <h1><span label="context">ConTeXt</a></h1>
        <span label="context">ConTeXt</a>
        <span label="tex">TeX</a>
        <span label="latex">LaTeX</a>
    </doc>
    \stopbuffer

    \setupinteraction[state=start]

    \startxmlsetups xml:initialize
        \xmlsetsetup{#1}{h1|span}{xml:*}
        \xmlsetsetup{#1}{span[@label]}{xml:logo}
        \xmlsetsetup{#1}{span[@label='context']}{xml:context}
    \stopxmlsetups

    \xmlregistersetup{xml:initialize}

    \startxmlsetups xml:h1
        \placecontent[criterium=all]
        \chapter{\xmlflush{#1}}
    \stopxmlsetups

    \startxmlsetups xml:logo
        \uppercasestring\xmlatt{#1}{label}\xmlatt{#1}{name}\to\ascii
        \ifx\ascii\empty\else\getvalue{\ascii}\fi
    \stopxmlsetups

    \startxmlsetups xml:context
        \ConTeXt
    \stopxmlsetups

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

xml:logo doesn’t work when it has to be parsed in a heading.

Is there a fix for xml:logo or is xml:context the proper fix?

Many thanks for your help,


Pablo

You’re mixing tags, each <span> ends with </a>.

You need a expandable version for your logo tags.

   \startxmlsetups xml:logo
       \getvalue{\utfupper{\xmlatt{#1}{label}}}
   \stopxmlsetups

You can also modify this and provide a text which appears when you try to show a logo which isn’t defined.

   \startxmlsetups xml:logo
       \executeifdefined{\utfupper{\xmlatt{#1}{label}}}{{\tttf ???}}
   \stopxmlsetups

Many thanks for your reply, Wolfgang.

You’re totally right. I wonder how ConTeXt compiled that.

This is exactly what I needed.
