Hallo,
it is possible to use TeX control sequence inside XML param? How? Example:
<figure file="file.pdf" width=".45\textwidth" /> ^^^^^^^^^^ \defineXMLenvironment[figure][file=,width=] {} {\externalfigure[\XMLop{file}][width=\XMLop{width}]}
Hm. You're lucky. We should make a test suite (at the wiki) to make sure that this kind of stuff keeps working -)
\starttext
\defineXMLentity[ctx-var-textwidth] {\textwidth}
I seeee! I might come to me... Actually I'd like to solve a bit more complex task: \starttext \defineXMLentity[ctx-var-textwidth] {\textwidth} \newcount\FigNo \defineXMLenvironment[float][] {\defineXMLpush[caption]% \global\FigNo=0 } {\placefigure{\XMLflush{caption}}% {\dorecurse{\FigNo}% {\edef\filewithpath{\XMLpop{dir-fig}\getvalue{file:\recurselevel}}% \edef\param{\getvalue{param:\recurselevel}}% \externalfigure[\filewithpath][\param]}}% } \defineXMLenvironment[figure][file=,context=] {} {\global\advance\FigNo by1 % \expanded{\setvalue{file:\the\FigNo}{\XMLop{file}}}% \expanded{\setvalue{param:\the\FigNo}{\XMLop{context}}}% } \startXMLdata <float> <figure file="cow.pdf" context="width=.5&ctx-var-textwidth;" /> <figure file="hacker.jpg" context="width=3cm" /> <caption>Cow and hacker.</caption> </float> \stopXMLdata \stoptext
