xml entities and trailing space

xml entities and trailing space

[Thomas A. Schmitz]

Hi all, Hans,

this is something I had mentioned a few weeks ago, but wanted to complain about it again: when you define xml entities as TeX commands, those used to preserve trailing spaces. This hasn't been the case since a number of version. I would like to recommend havin the old behavior back (since adding spaces isn't as easy in xml as it is in TeX). The example below demonstrates the problem.

All best

Thomas

\startbuffer[xmltest]
<p>A &textbar; B</p>
\stopbuffer

\startxmlsetups xml:mysetups
    \xmlsetsetup{\xmldocument}{p}{xml:*}
\stopxmlsetups

\xmlregistersetup{xml:mysetups}

\startxmlsetups xml:p
    \xmlflush{#1} \par
\stopxmlsetups

\xmlsetentity{textbar}{\textbar}

\starttext
\xmlprocessbuffer{main}{xmltest}{}
\stoptext

this is not that easy as effectively

A&textbar; B

becomes

A\textbar B

and tex will normally gobble that space as part of parsing the input and 
changing that aspect will not happen

chicken or egg so use:

\xmlsetentity{textbar}{\textbar{}}

OK, will do that - I was just curious because the behavior changed a while ago. I have older pdfs where  the space after such entities was preserved. But you're right, it's no big deal.
