More on XML and citations

[Johannes Graumann]

Hello again,

I have a matching rule for cite commands that look as follows:
<cite id="hunt:86" opt="authoryear"/>

The rule is this (kudoos to Taco):
\defineXMLargument
  [cite]
  {\expanded{\cite[\XMLpar{cite}{opt}{}][\XMLpar{cite}{id}{}]}}

Sometimes I would like to have the '(Hunt et. al., 1986)' produced by above
combination to look like '(see e.g. Hunt et. al., 1986)'. Taco pointed out
in response to a question to list that I could do that by handing
a 'left={(see e.g. }' to the cite command, however I fail to be able to do
that. A XML node like this 
<cite id="hunt:86" opt="authoryear,left={(see e.g.}"/>
results on compilation with above rule in the following error:
! Missing \endcsname inserted.

                   \leftargument

Can anybody help me out with this?

- reset opt, otherwise the previous one will be used when no opt is given
- \XMLop (own parameter) saves a few bytes and can be used here

\defineXMLargument
  [cite]
  [opt=]
  {\expanded{\cite[\XMLop{opt}][\XMLop{id}]}}

hm, the problem is that the { } are  no longer tex's braces (grouping)

\starttext

\defineXMLcommand
  [whatever]
  [test=unknown]
  {\XMLop{test}}

\startXMLdata
<whatever test="{\bf test}"/>
\stopXMLdata

\def\defXMLtex#1#2% the appended space will go away when
  {\begingroup    % \scantokens is fixed
   \disableXML
   \everyeof{\noexpand}% br's hack
   \edef\ascii{#2}%
   \edef\ascii{\scantokens\expandafter{\ascii}}% space appended
   \expandafter\endgroup\expandafter\def\expandafter#1\expandafter{\ascii}}
  
\defineXMLcommand
  [whatever]
  [test=unknown]
  {\defXMLtex\SomethingTex{\XMLop{test}}%
   \SomethingTex}

\startXMLdata
<whatever test="{\bf test}"/>
\stopXMLdata

\stoptext

so, then you can for instance feed \SomethingTex into the scite macros

however, best is not to mix tex this way with xml

Hmmmm ... will heed that advice then ... as a remedy: Taco, how would I
define a new 'cite' alternative along the lines
of 'authoryear'/'authoryears' that would result in 'Author et. al., 2004'?

Thanks for any hint, Joh

Easiest is by using a special macro breaking it up in two bits, like so:

   \def\mycite#1{\cite[author][#1], \cite[year][#1]}

there is a way to create 'official' alternatives, but it is quite a
bit more cumbersome.

Cheers, taco

Thanks for that. The problem here is that I use XML as the text source and
would like to be able to use 'authoryear', 'authoryears' as well
as 'mycite' occasionally, which I switch to and from by the 'opt' option in
e.g.  '<cite id="hunt:86" opt="authoryear"/>'. If I understand your above
proposal correctly, I would have to literally call '\mycite[hunt:86]' on
the TeX level, and would have to abandon XML ... and thus the reason to
switch from LaTeX to ConTeXt to begin with - and nobody would want that ;0)
Could you - maybe - point me towards the more cumbersome 'official'
solution?

Thanks for your help,

Joh

Taco,

Yes. Get the new one from http://modules.contextgarden.net/bib
or wait 'till the new context release (tomorrow, i believe).
