Subject: parameter setting
Date: Sat, 16 Jun 2012 12:11:46 +0000 [thread overview]
Message-ID: <4E63CEE0-BC3A-4C66-91FB-DEF9FF197BE4@uva.nl> (raw)
In order to be able to use attributes on xml-nodes freely, the following situations can arise:
The foregroundcolor parameter gets a value:
<node color="red"> correctly sets ..[foregroundcolor=\xmlatt{#1}{color}] color to red.
However, in the next case the current foregroundcolor should be left as is, but reverts to black:
<node> ..[foregroundcolor=] and is apparently reset to the general default.
trying the following seemed the solution, but it does not work:
..[\doifnot{\xmlatt{#1}{color}}{\empty}{foregroundcolor=\xmlatt{#1}{color}}]
giving in the log:
{foregroundcolor=orange}' in line 16 (249>:)
check > missing or ungrouped '=' after '\doifnot {}{}
Putting the above \doif inside an \expanded{} does not alter the behaviour.
How to accomplish leaving the parameter as is for an absent attribute?
