ConTeXt, XML, multiple attributes evaluation
Hello again, Another one: I'm trying to expand
\defineXMLenvironment [list]% {% \expanded{% \startitemize% [% \XMLifequalelse{list}{packed}{yes}{packed}{unpacked}% ]% }% }% {\stopitemize}
which can deal with things like
<list packed="yes"> <item> </item> </list>
To something able to deal with multiple attributes (a "setup" statement for now):
<list packed="yes" setup="n"> <item> </item> </list>
I have tryed multiple incarnations of
\defineXMLenvironment [list]% {% \expanded{% \startitemize% [% \XMLifequalelse{list}{setup}{n}{n}{},% \XMLifequalelse{list}{packed}{yes}{packed}{unpacked}% ]% }% }% {\stopitemize}
but this doesn't work ... Can anybody give me any pointers here? Thanks for time and help, Joh -- +----------------------------------------------------------------------+ | Johannes Graumann, Dipl.

Hello Johannes, I consider your first \XMLifequalelse command a bit strange. This command is intented to be used if you want to convert the attribute values into something else (e.g. "yes" into "packed"). If you need the unmodified parameter value, simply use \XMLpar. So e.g.: \startitemize[ \XMLpar{list}{setup}{}, \XMLifequalelse{list}{packed}{yes}{packed}{unpacked} ] Of course "setup" should be a required attribute of <list> (in your DTD), otherwise it would lead to something like \startitemize[,packed] which obviously wouldn't work at all. If it's not the case, I'd use \doifXMLparelse: \doifXMLparelse{list}{setup}{% \startitemize[ \XMLpar{list}{setup}{}, \XMLifequalelse{list}{packed}{yes}{packed}{unpacked} ]% }{% \startitemize[1, \XMLifequalelse{list}{packed}{yes}{packed}{unpacked} ] } -Richard _____ From: Johannes Graumann [mailto:graumann@caltech.edu] To: ntg-context@ntg.nl Sent: Tue, 29 Nov 2005 05:30:25 +0100 Subject: [NTG-context] ConTeXt, XML, multiple attributes evaluation Hello again, Another one: I'm trying to expand

a convenient way is to use the remapper: \mapXMLvalue {list:packed} {yes} {packed} \mapXMLvalue {list:packed} {no} {unpacked} and then: \defineXMLenvironment [list] [packed=no] {\startitemize[\XMLval{list:packed}{\XMLop{packed}}{}]} {\stopitemize} no fuzzy testing involved, just expansion (fast and clean) Hans

But it worked fine for me!? Anyway, it is probably a better idea to do it like this: \defineXMLenvironment [list]% {% \let\listoptions\empty \XMLifequalelse{list}{setup}{n} {\appendtocommalist{n}\listoptions} {}% \XMLifequalelse{list}{packed}{yes} {\appendtocommalist{packed}\listoptions} {\appendtocommalist{unpacked}\listoptions}% \expanded{% \startitemize[\listoptions]% }% }% {\stopitemize} Because that way, the xml attributes can be optional. If it still doesn't work, please explain what goes wrong. Greetings, Taco

Do you see any way of generalizing the "XMLifequalelse{list}{setup}{n}" part? Could I just have the argument of "<list setup="whatever">" handed thtough to ConTeXt rather than writing if-loops for n,a,A,KA,r,R,KR,m,g,G,1,2,3,4,5,6,7,8?

that's what mapXMLvalue is for Hans
Hans, I'm just not getting it ... can't find the appropriate documentation maybe? http://www.pragma-ade.nl/general/manuals/example.pdf is all I got and e.g. "XMLop" does not show up at all in there ...

XMLop{xx} is a shortcut for \XMLpar{list}{xx}{some default} and as long as the current element is list that will work, so \defineXMLenvironment[list] {here \XMLop{xx} works fine} {but here the last element encountered may be another than list}

This works ok here: \mapXMLvalue {list:packed} {yes} {packed} \mapXMLvalue {list:packed} {no} {unpacked} \defineXMLenvironment [list] [packed=no,setup=1] {\startitemize[\XMLop{setup},\XMLval{list:packed}{\XMLop{packed}}{}]} {\stopitemize} \defineXMLenvironment [item] {\item} {\endgraf} \starttext \startXMLdata <list packed='yes'> <item>item one</item> <item>item two</item> </list> \stopXMLdata \startXMLdata <list> <item>item one</item> <item>item two</item> </list> \stopXMLdata \startXMLdata <list packed='yes' setup='a'> <item>item one</item> <item>item two</item> </list> \stopXMLdata \startXMLdata <list setup='a'> <item>item one</item> <item>item two</item> </list> \stopXMLdata \stoptext (it may help to look at the x-* files in the context/base path) Hans
