There I don't find something which helps me.
The input must not be only XML. In can also be CVS or something
else...

You will have to convert your XML file to become a ConTeXt table, use  
XSLT or some scripting language.
ConTeXt's TABLE format ("HTML tables") is very suitable for such.

I'm not sure I understand the "CVS or something else" part from the
original poster, but XML-style tables can very feasibly be mixed with
other ConTeXt code:

\usemodule        [contml]  % load the simple default xml vocab
\autoXMLnamespace [context] % avoid prefixing elements w/ context:
\setupcolors      [state=start] % not necessary, helps with example

\starttext
\section{Some \ConTeXt}

\startXMLdata
<table frame="off" background="color" color="white">
<tr backgroundcolor="red">   <td>some</td> <td>XML</td> </tr>
<tr backgroundcolor="green"> <td>xx</td> <td>xx</td> </tr>
</table>
\stopXMLdata

I can also have normal \TeX-like 
\inframed[frame=off,background=color,backgroundcolor=yellow]
{markup}.

\stoptext

You can replace the \startXMLdata-\stopXMLdata block with (in this case)
\processXMLfilegrouped{table.xml} where table.xml holds a table similar
to the above.

 Probably a typo for CSV, comma-seperated values.

 It should be rather easy to typeset csv data in table format.  The
following tentative code ignores the fact that csv data may optionally
be enclosed in "" quotes that have to be removed (to be done in
TBLentry) and that these quoted strings may contain commas themselves
(which means writing a custom version of \processcommalist instead).
Apart from that, it seems to work.  (I just felt an urge of creativism,
so I took up the challenge.)


\def\TBLentry#1{\bTD#1\eTD}
\def\TBLline#1{\bTR\processcommalist[#1]\TBLentry}

% Iterate over all the lines of text captured with \obeylines active
% command to call is first argument, is not called for empty lines
\bgroup
\obeylines
\gdef\ProcessLines#1#2{\doProcessLines{#1}#2^^M\doProcessLines}%
\gdef\doProcessLines#1#2^^M#3\doProcessLines{%
  \doifnotempty{#2}{#1{#2}}%
  \doifnotempty{#3}{\doProcessLines{#1}#3\doProcessLines}%
}%
\egroup

\def\startCSV{\bgroup\obeylines\dostartCSV}

\def\dostartCSV#1\stopCSV{%
   \bTABLE
   \ProcessLines\TBLline{#1}%
   \eTABLE
   \egroup
}


\starttext
CSV test:

\startCSV
a,b,c,d,e
1,2,3,4,5
6,7,8,9,10
some text,11,12,,14
\stopCSV

\stoptext


 Hans, what goodies of ConTeXt did I miss?  Is the above sufficiently
ConTeXtish to be wikiable?
