Happy New Year! How would you implement a mechanism that takes arbitrary XHTML <meta> tags and produces document variables? Consider: <meta name="journal" content="Nature" /> 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] <html> <head> <meta content="Milena Marić Einstein" name="author"/> <meta content="Annalen der Physik" name="journal"/> </head> <body> </body> </html>\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!
