Hi to all,

I' ve started playing with xml --> context.
I've read the docs but even if I am able to do some very basic  
operation I'm in troubles doing my first real experiment.

I've  already generated a book from the collection of html help files  
of the SuperCollider language using a cumbersome python script.
But I was guessing that probably using xml mapping would make my life  
easier.

An example file  to be processed is here:
http://supercollider.svn.sourceforge.net/viewvc/supercollider/trunk/ 
build/Help/Style%20Guide/Documentation%20Style%20Guide.html?view=log

The html is w3c compliant and being automatically generated seems to  
be consistent.

I'm able to do easily stuff like this, which is a promising start:

\startenvironment scEnv
\enableregime[utf]
\defineXMLenvironment [body] \starttext \stoptext
%\defineXMLenvironment [style] \starthiding \stophiding
\defineXMLcommand [p] \par
\defineXMLgrouped [b] \bf
\stopenvironment


But:
1. how do I simply skip undesired tags? The \start-\stophiding trick  
(which in any case does not work: why?) was a hack in order to not  
typeset the stile tags
2. how can i map class attributes in order to specify for each of  
them e.g fontname, points, color, indenting?

Thanks as usual

Best

I did this interview where I just mentioned that I read Foucault. Who  
doesn't in university, right? I was in this strip club giving this  
guy a lap dance and all he wanted to do was to discuss Foucault with  
me. Well, I can stand naked and do my little dance, or I can discuss  
Foucault, but not at the same time; too much information.

Indeed, lxml under python is a cool module.
See
http://codespeak.net/lxml/
lxml_in_python  implements also full xpath/xslt

> An example file  to be processed is here:

Please ,if you can, consider luatex+context mkiv; in base folder see
l-xml-edu.lua  lxml-ini.lua  lxml-ini.tex  l-xml.lua
(warning : lxml here has nothing to do with lxml in python, only the same names)
I believe that actually lxml_in_luatex does not implements a full xpath/xslt,
because  not always these are useful in this context.

(If I need a full xpath/xslthere here, then I have a too much complex
xml document, and I preprocessing it with lxml_in_python)

With lxml_in_python_ and lxml_in_luatex_
you can solve all ** reasonable ** problems.
Sometimes only lxml_in_python is need, sometimes only lxm_in_luatex, it depends.

these are in fact buffers and buffers work on the unexpanded input stream

\defineXMLignore[style]

\mapXMLvalue cum suis ... see x-* files for examples

(in mkiv one can use a mixed tree/streem based model)

Ciao Luigi,

grazie.
I didn't know about lxml. Very goo dto know.
But the idea was to "stay inside" ConTeXt so to be able to generate  
the pdf from inside SuperCollider using the provided  interface to bash.
I'd like to consider luatex, but I'm only a bit scaredby
- installation issued (so I'm waitin for a TeXlive release)
- documentation. (where's lxml_in_luatex documentation? I guess in  
sources)

Best

Where? I'm still having difficulties in knowing how to find sources,  
plus on macosx these are typically hidden files so I have to make  
some tricks to have them searchable.

Do you mean using \executesystemcommand ?
Be careful, thing can be slow down

hmm, why don't give it a try ?
You are under linux, isn't it ?
It should be not so difficult to setup a context-mkiv, and
mkiv will be the way .

Ah, macosx , not linux.
BTW
http://minimals.contextgarden.net/
can help to setup a mkiv context

Grazie Luigi,

I'm a bit scared because I'n not a unix person (at least, still) so  
when I encounter some troubles I'm always blocked.

Could anyone write few lines in the wiki to explain how and where to  
extract doc information from sources?
I'm always finding some difficulties in snooping inside ConTeXt
Or if it is discussed on the mailing list I can wikify the results.
