Hi all,
I'm testing the possibilities of xml and ConTeXt. I was wondering if it
is possible to make an extra setup for every text-element. So it would
be possible to have an setup in a very flexible way. It should be
something like this:
\startbuffer[text]
<a>
<b>
First text.
<hiding type="begin"/>
Second text.
</b>
Third text.
<hiding type="end"/>
Fourth text.
</a>
\stopbuffer
\startxmlsetups xml:textsetups
\xmlsetsetup{#1}{a|b}{xml:*}
\xmlsetsetup{#1}{hiding[type='begin']}{xml:hiding:begin}
\xmlsetsetup{#1}{hiding[type='end'}{xml:hiding:end}
\xmlsetsetup{#1}{text()}{xml:text} % Something like this is needed
\stopxmlsetups
\startxmlsetups xml:a
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:b
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:hiding:begin
\enablemode[hiding]
\stopxmlsetups
\startxmlsetups xml:hiding:end
\disablemode[hiding]
\stopxmlsetups
\startxmlsetups xml:text
\startnotmode[hiding]
\xmlflush{#1}
\crlf
\stopnotmode
\stopxmlsetups
So that the result will be:
First text.
Fourth text.
Is something like this possible or is there still another way?
it really depends on how the nesting works out as explicit grouping can 
interfere

\startbuffer[text]
<a>
   <b>
     First text.
     <hiding type="begin"/>
     Second text.
   </b>
   Third text.
   <hiding type="end"/>
   Fourth text.
</a>
\stopbuffer

\startxmlsetups xml:textsetups
     \xmlsetsetup{#1}{a|b|hiding}{xml:*}
\stopxmlsetups

\xmlregistersetup{xml:textsetups}

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

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

\startxmlsetups xml:hiding
     \doifelse {\xmlatt{#1}{type}} {begin} {
         \startnointerference
     } {
         \stopnointerference
     }
\stopxmlsetups

\starttext
     \xmlprocessbuffer{main}{text}{}
\stoptext

maybe it makes sense to have a 'hide' flag built in the serializer (or 
maybe some explicit stream related hooks)
