(I'll check whether I can link to that page from somewhere.) But there's no (high-level) way to apply certain commands to this list elements, right? Background: My real use case is a bit more complex. I use comma separated lists to store author lists, but the authors themselves are saved in structured variables. So, I'll need to reassemble the different name parts first. So, nothing like \commalistprocessandmakesentence[a,b,c]\commandforfirst\commandforinbetween\commandforlast Probably to specific, right? %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \startbuffer[test] <?xml version='1.0' standalone='yes?> <document> <title>This is the title</title> <author> <family-name>Doe</family-name> <given-name>John</given-name> </author> <author> <family-name>Smith</family-name> <given-name>Jane</given-name> </author> <p>This is a first sentence</p> </document> \stopbuffer \startxmlsetups xml:setup \xmlsetsetup{\xmldocument}{*}{-} \xmlsetsetup{\xmldocument}{document|p}{xml:*} \stopxmlsetups \xmlregistersetup{xml:setup} \startxmlsetups xml:document \xmlfilter{#1}{/title/command(xml:title)} \xmlfilter{#1}{/author/command(xml:author)} \startdocument \xmlflush{#1} \stopdocument \stopxmlsetups \startxmlsetups xml:title \setupdocument[title={\xmlflush{#1}},author={\AuthorList}] \stopxmlsetups \startxmlsetups xml:author:family-name \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:author:given-name \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:author \defineauthor[\xmlfilter{#1}{/family-name/command(xml:author:family-name)}\xmlfilter{#1}{/given-name/command(xml:author:given-name)}][family-name={\xmlfilter{#1}{/family-name/command(xml:author:family-name)}},given-name={\xmlfilter{#1}{/given-name/command(xml:author:given-name)}}] \addtocommalist {\xmlfilter{#1}{/family-name/command(xml:author:family-name)}\xmlfilter{#1}{/given-name/command(xml:author:given-name)}} \AuthorList \stopxmlsetups \startxmlsetups xml:p \xmlflush{#1}\par \stopxmlsetups \definenamespace [documentauthor] % name of internal varialbles [type=module, name=author, command=yes, % Create \defineauthor style=yes, % Create \useauthorstyleandcolor setup=list, % Create \setupauthor parent=documentauthor, ] \def\AuthorList{} \define[1]\useauthor {\edef\currentauthor{#1}% {\authorparameter{given-name} \space \authorparameter{family-name}}} \startsetups document:start \documentvariable{title}\endgraf \blank[medium] \processcommacommand[\documentvariable{author}]\useauthor \endgraf \stopsetups \xmlprocessbuffer{main}{test}{} ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 4+ messages in thread
