Hi everyone,
I am attempting to map some XML into ConTeXt as described in the manual
"XML in ConTeXt". Essentially we have a bunch of tagged text (the XML
"loosely" based on some of the XHTML tags) from which we want to produce
PDF letters for dispatch (via email, post etc).
I am having particular problems implementing the following commands: -
\underbar, \underbars, \overstrike, \overstrikes, \low, \high and
\lohi
I was expecting that they would all easily be defined using the
\defineXMLgrouped [name] {command} element mapping. There is probably
something very simple that I have not setup correctly since I am sure that
this has been attempted before and would appreciate pointers as to where I
am going wrong.
The following attempts at mapping element <u> to \underbar illustrates my
problem which also seems largely applicable to the <strike>, <sub> and
<sup> mapping: -
1. This def of <u> does nothing ...
\defineXMLgrouped [u] \underbar
2. This def of <u> also does nothing ...
\defineXMLgrouped [u] {\groupedcommand{\underbar}{}}
3. This def of <u> underlines the 1st character only ...
\defineXMLenvironment [u] {\bgroup\underbar} {\egroup}
4. In the mailing list, there is a suggestion that \underbar does not
allow line-breaking, so I also tried the following. This def of <u>
"works" partially, in that it does underline, however it causes havoc with
alignment - everything seems to shift over to the right about 4cm ...
\defineXMLenvironment [u] \startul \stopul
\definetextbackground[ul]
[location=text,alternative=1,background=,frame=off]
\definestartstop[ul]
[before={\starttextbackground[ul] },
after={\stoptextbackground\ }]
Below is a sample .tex file that I have been playing with: -
\usemodule [contml]
\autoXMLnamespace [context]
% Attempts at defining a mapping for <u>: -
% This def of <u> does nothing ...
%\defineXMLgrouped [u] \underbar
% This def of <u> does nothing ...
%\defineXMLgrouped [u] {\groupedcommand{\underbar}{}}
% This def of <u> underlines the 1st character only ...
%\defineXMLenvironment [u] {\bgroup\underbar} {\egroup}
%
% This def of <u> "works" partially, in that it does underline, however it
% causes havoc with alignment - everything seems to shift over to the
right
% about 4cm ...
\defineXMLenvironment [u] \startul \stopul
\definetextbackground[ul]
[location=text,alternative=1,background=,frame=off]
\definestartstop[ul]
[before={\starttextbackground[ul] },
% after={\stoptextbackground\fixedspaces}]
after={\stoptextbackground\ }]
% Other mappings
\defineXMLgrouped [right] \rightaligned
\defineXMLgrouped [centre] \midaligned
\defineXMLgrouped [em] \em
\defineXMLsingular [br] [nr=1]
{\blank[\XMLop{nr}*medium]}
\showstruts \showframe
\starttext
start of 'normal' \CONTEXT\ text
\underbar{This} is {\em left} aligned
\blank[medium]
\rightaligned{\underbar{This} is {\em right} aligned}
\blank[medium]
\midaligned{\underbar{This} is {\em centre} aligned}
end of 'normal' \CONTEXT\ text - starting xml ...
\startXMLdata
<p>This is <em>left</em> aligned</p>
<p><centre><u>This</u> is <em>centre</em> aligned</centre></p>
<p><centre>This is <em>centre</em> aligned</centre></p>
<p><right>This is <em>right</em> aligned</right></p>
\stopXMLdata
\blank[medium]
finished xml - back in 'normal' \CONTEXT\ text
\stoptext
