Here some works on xml and context

setupcolors[state=start,rgb=no,cmyk=yes]
\defineXMLenvironment [node][type=]
{%Start tag
%{\ss\tfx attr type=''\XMLpar{node}{type}{}''}
\expanded{\beforesplitstring{\XMLpar{node}{type}{}}}\at [\to\Type%  
\expanded{\aftersplitstring{\XMLpar{node}{type}{}}}\at [\to\rawOptions%  
\expanded{\beforesplitstring{\rawOptions}}\at ]\to\Options%  
%{\ss\tfx Type=\Type}\par
%{\ss\tfx Option=\Options}\par
\doifelse{\Type}{framedtext}%
  {%then
  \expanded{\framed[\Options]}\bgroup
  }{%else

}
{%End tag
\egroup
 %%{\blank\ss$<$/node$>$\blank}
}

\starttext
\processXMLfilegrouped{test-5.xml}
{\tfx
\typefile{test-5.xml}}
\stoptext

and test-5.xml is 

<?xml version="1.0" ?>
<node type="framedtext[frame=off,topframe=on,
                       background=color,
                       backgroundcolor=cyan,
                       rulethickness=3pt]">

<node type="framedtext[frame=off,bottomframe=on,
                       background=color,
                       backgroundcolor=magenta,
                       rulethickness=3pt]">

<node type="framedtext[frame=off,leftframe=on,
                       background=color,
