How would you implement a mechanism that takes arbitrary XHTML
tags and produces document variables? Consider:
After running XML setups, the following would write "Nature":
\documentvariable{journal}
The tricky part is doing this without pre-defining them. Here's a short,
self-contained example to help demonstrate:
|\startbuffer[xdoc] name="author"/>
\stopbuffer \startxmlsetups xml:xhtml
\xmlsetsetup{\xmldocument}{*}{-}
\xmlsetsetup{\xmldocument}{html|body}{xml:*}
\xmlsetsetup{\xmldocument}{head}{xml:meta} \stopxmlsetups
\xmlregistersetup{xml:xhtml} \startxmlsetups xml:html
% "author" is a special setup, not generalized
\xmlfilter{#1}{/head/meta[@name='author']/command(xml:author)} % What
goes here to make this dynamic?
%\xmlfilter{#1}{/head/meta[@name='journal']/command(xml:journal)}

[NTG-context] Dynamic document variables from metadata
Happy New Year!
How would you implement a mechanism that takes arbitrary XHTML tags
and produces document variables? Consider:
After running XML setups, the following would write "Nature":
\documentvariable{journal}
The tricky part is doing this without pre-defining them. Here's a short,
self-contained example to help demonstrate:
\startbuffer[xdoc]
\stopbuffer
\startxmlsetups xml:xhtml
\xmlsetsetup{\xmldocument}{*}{-}
\xmlsetsetup{\xmldocument}{html|body}{xml:*}
\xmlsetsetup{\xmldocument}{head}{xml:meta}\stopxmlsetups
\xmlregistersetup{xml:xhtml}
\startxmlsetups xml:html
% "author" is a special setup, not generalized
\xmlfilter{#1}{/head/meta[@name='author']/command(xml:author)}
% What goes here to make this dynamic?
%\xmlfilter{#1}{/head/meta[@name='journal']/command(xml:journal)}
\xmlflush{#1}\stopxmlsetups
\startxmlsetups xml:author
\setupdocument[author={\xmlatt{#1}{content}}]
\setupdocument[metadata:author={\xmlatt{#1}{content}}]
\setupinteraction[author={\documentvariable{author}}]\stopxmlsetups
% How can this be generalized?%\startxmlsetups xml:journal
%\setupdocument[journal={\xmlatt{#1}{content}}]%\stopxmlsetups
\startxmlsetups xml:body
\startdocument
Author: \documentvariable{author}
\par
Journal: \documentvariable{journal}
\stopdocument\stopxmlsetups
\xmlprocessbuffer{main}{xdoc}{}
Thank you!
