XML & ConTeXt -- handling many conventions

XML & ConTeXt -- handling many conventions

[Pawel Jackowski na WP]

Hi!

There is a lot of ways to build ConTeXt macro which can handle something
like i.e:

<chapter title="First Chapter">
...
or

<chapter>
<title>First Chapter</title>
...

But is there any way to handle both conventions in one defnition?



Regards, Paweł

Hello Pawe³ (I, hope your name comes out OK; I cut & pasted your
signature, which on my news-reader looks like "Pawe${}^3$")

The element <chapter title="First Chapter"> is wrong.  By burying your
title in an attribute you're making it neither easily searchable nor
useble by other applications.

Your alternative XML snippet is much better:

<chapter>
   <title>First Chapter</title>
...
</chapter>

The general rule of thumb for when to use attributes and when to use
elements is: use elements for presentable data and attributes for
system data.  In this case where you're presenting the title "First
Chapter" to the context-processor to be marked up as a chapter title,
it is definitely presentable data, and therefore it belongs in an
element.

Actually no, but don't worry. I'm aware that polish 'lslash' may not be
displayed properly. But using polish characters is the only way
to protect them from extinction. I will think about some compromise.

That is what I said to my boss. The problem is that J have to build
something more or less universal because
I don't known who will prepare XML documents and which convention will be
used.

Thanks, I will remember. It looks convincing.

indeed. concerning attributes, i use 'm for

   <title label="the first">First Chapter</title>

permits you to analyze a label without the need to look into the element text.
