xml and lpath

xml and lpath

[Martin Fechner]

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?

Best regards,

Martin

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)

Thank you very much. Now every thing works. It helps me a lot. I am glad 
about such possibilities with XML and ConTeXt.
