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
