Hello Hans, just to remind the other issues. The code from xml-mkiv.pdf doesn't work as expected. Only in \TestMode=2 the index is rendered as supposed. demo.tex + demo.xml below Jano %%%%%%%%%% % demo.tex \newcount\TestMode \TestMode=0 % expansion=xml %\TestMode=1 % expansion=yes, index, setup %\TestMode=2 % expansion=yes \startxmlsetups xml:mysetups \xmlsetsetup{\xmldocument}{demo|index|content|chapter|title|em}{xml:*} \stopxmlsetups \xmlregistersetup{xml:mysetups} % main document \startxmlsetups xml:demo \xmlflush{#1} \subject{contents} \placelist[chapter][criterium=all] \subject{index} \placeregister[index][criterium=all] \page % else buffer is forgotten when placing header \stopxmlsetups \startxmlsetups xml:chapter \ifcase \TestMode % xml code travels around \setuphead[chapter][expansion=xml] \startchapter[title=eh: \xmltext{#1}{title}] \or % index is used for access via setup \setuphead[chapter][expansion=yes,xmlsetup=xml:title:flush] \startchapter[title=\xmlgetindex{#1}] \or % tex call to xml using index is used \setuphead[chapter][expansion=yes] \startchapter[title=hm: \xmlreference{#1}{xml:title:flush}] \fi \xmlfirst{#1}{content} \stopchapter \stopxmlsetups \startxmlsetups xml:title:flush \xmltext{#1}{title} \stopxmlsetups % We need to deal with emphasis and the content of the chapter. \startxmlsetups xml:em \begingroup\em\xmlflush{#1}\endgroup \stopxmlsetups \startxmlsetups xml:content \xmlflush{#1} \stopxmlsetups %A similar approach is followed with the index entries. Watch how we use the numbered entries variant (in this case we could also have used just entries and keys. \startxmlsetups xml:index \ifcase \TestMode \setupregister[index][expansion=xml,xmlsetup=] \setstructurepageregister [index] [entries:1=\xmlfirst{#1}{content}, keys:1=\xmltext{#1}{key}] \or \setupregister[index][expansion=yes,xmlsetup=xml:index:flush] \setstructurepageregister [index] [entries:1=\xmlgetindex{#1}, keys:1=\xmltext{#1}{key}] \or \setupregister[index][expansion=yes,xmlsetup=] \setstructurepageregister [index] [entries:1=\xmlreference{#1}{xml:index:flush}, keys:1=\xmltext{#1}{key}] \fi \stopxmlsetups \startxmlsetups xml:index:flush \xmlfirst{#1}{content} \stopxmlsetups % The file is processed by: \starttext \xmlprocessfile{main}{demo.xml}{} \stoptext % additional control %\startxmlsetups xml:ctx:sectionentry %\xmlflush{#1} %\stopxmlsetups %\startxmlsetups xml:ctx:registerentry %\xmlflush{#1} %\stopxmlsetups %%%%%%%%%% % demo.xml <?xml version='1.0' ?> <demo> <chapter> <title>Some <em>short</em> title</title> <content> zeta <index> <key>zeta</key> <content>zeta again</content> </index> alpha <index> <key>alpha</key> <content>alpha <em>again</em></content> </index> gamma <index> <key>gamma</key> <content>gamma</content> </index> beta <index> <key>beta</key> <content>beta</content> </index> delta <index> <key>delta</key> <content>delta</content> </index> done! </content> </chapter> </demo>
