MkIV XML and |c|c|c|

MkIV XML and |c|c|c|

[Kate F]

Hi,

I'm trying to glue MkIV XML handling to ConTeXt's tabulation. My
markup has a HTML-style table model, with an arbitary number of <col>
elements.

My problem is to produce the |c|c|c|c| format based on the number of
<col> elements I have, rather than hardcoding a specific number of
columns.

I thought I could do something like this, but unfortunately the string
produced by \xmlconcat{#1}{col}{\|} seems to be ignored:

    % in practice this would produce various alignments, not just "c"
    \startxmlsetups xml:col
        c
    \stopxmlsetups

    \startxmlsetups xml:table
        \starttabulate[\|\xmlconcat{#1}{col}{\|}\|]
        \xmlall{#1}{thead|tbody}
        \stoptabulate
    \stopxmlsetups

Whereas this works fine, as I'd expect: \starttabulate[|c|c|c|c|]

(I'm also confused about the escaping for \| there. I guess the [] is
a special environment, with | being given a different catcode,
perhaps?)

Is there a way to do this, with the number of columns and their
alignment generated from the input XML?

Thanks,

-- 
Kate

I have done some things with html-xml. Perhaps looking into the following ConTeXt code will help you to find how to do things. Hope it helps.
