arbitrary context commands in xml file

arbitrary context commands in xml file

[denis.maier]

Hi
Is there a way to add arbitrary context commands to an xml file without defining an injector first?

I mean without breaking the xml of course. Something like an ad hoc injector...

Thanks. But won't that break the xml? I'll need a new element for this right? But what if the schema doesn't allow this?

Re: arbitrary context commands in xml file

[denis.maier]

Just to provide more information about what I was thinking:
You do your typesetting based on an XML doc. Now it is time for the finishing touches. In a tex document you'd add the usual commands to manipulate the layout:
\adaptlayout[lines=+1]
 \testpage[3]
\looseness=-1 / \looseness=+1
\blank 
\setuptolerance 
etc.

Now, of course you can define an injector for these commands, some are predefined, like page, column, blank.
But, if my understanding is correct, you'd have to define one for each of the possible parameters.

So, you'll need:

\startsetups xml:directive:injector:testpagethree
\testpage[3]
\stopsetups

\startsetups xml:directive:injector:testpagefour
\testpage[4]
\stopsetups

etc., and

\startsetups xml:directive:injector:addoneline
\adaptlayout[lines=+1]
\stopsetups

\startsetups xml:directive:injector:addtwolines
\adaptlayout[lines=+1]
\stopsetups

Here, I was thinking if something like this could be easier:

<?context-directive raw-tex-injector \testpage[4]?>

Wolfgang's solutions seems to provide that with different means. If I understand correctly, you'd just map an arbitrary XML element to this setup, and you can then do this:

<rawtex>
\testpage[4]
</rawtex>

Correct?

If yes, that would be a nice solution, but those elements  are probably not allowed if your document needs to be validated against a schema, yet processor instructions will be ignored during validation.

Any ideas for alternative approaches? What do you think about a raw-tex injector? (Another possibility would be to use Wolfgang's suggestion, and then to use an XSLT stylesheet to remove those illegal nodes for validation purposes...)

Best,
Denis

you can also do this:

<testpage n="4"/>

\startxmlsetups xml:testpage
   \testpage[\xmlatt{#1}{n}]
\stopxmlsetup

and register that one (as in previous examples)

Thanks,. That's a good idea, but it will also make the XML invalid.

I'd like to second Denis' request for support for XML processing
instructions to execute ConTeXt code, rather than elements which can cause
big problems if one is working to a fixed schema. It would be a boon to be
able to drop in <?context \whatever{fdfd}?> in an XML source.

one of the things that can already be done ...

\def\xmltexdirective#1#2{\doif{#1}{command}{#2}}

\xmlinstalldirective{tex}{xmltexdirective}

         <?context-directive tex command \inframed{xxx} ?>
         <?context-directive tex command \page ?>

(the #2 is something without spaces btu one can work around that)
