Hi all, I thought I had done this and it was easy, but I can't find a solution: I want to test whether a xml tag has an attribute and vary the typeset content accordingly. There used to be \xmldoifelseempty, but that has been commented out (lxml-ini.mkiv). What else could I use? Here's a small test that shows what I'm trying to do: \startbuffer[test] <a> <b>some text</b> <b important="different">more text</b> </a> \stopbuffer \startxmlsetups xml:testsetups \xmlsetsetup{\xmldocument}{a|b}{xml:*} \stopxmlsetups \xmlregistersetup{xml:testsetups} \startxmlsetups xml:a \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:b \xmldoifelse{#1}{./[@important]} %\doifemptyelse{\expanded{\xmlatt{#1}{important}}} {\color[darkred]{NOTEMPTY: \xmlatt{#1}{important}}\par} {\color[darkblue]{EMPTY: \xmlflush{#1}\par}} \stopxmlsetups \starttext \xmlprocessbuffer{main}{test}{} \stoptext Hints appreciated! All best Thomas
