Hi all, First of all a big thank you to Hans for MkIV xml support which is so much easier to understand than the MKII based method (or is that just me?) Anyway, I'm processing a rather messy html file and I would like to do some conditional processing based on the actual content of the element. See example below: I have linked <h3> with \subject but I would like to drop this element if the content of the element matches 'Skip title'. Any hints? Thanks! Jelle \startbuffer[test] <html> <h3>Title 1</h3> <p>Hello world.</p> <h3>Skip title</h3> <p>Hello world!</p> <h3>Title 2</h3> <p>Hello world?</p> <h3>Title 3</h3> <p>Hello :-)</p> </html> \stopbuffer \startxmlsetups xml:setups \xmlsetsetup{main}{html|h3|p}{xml:*} \stopxmlsetups \xmlregistersetup{xml:setups} \startxmlsetups xml:html \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:h3 \subject{\xmlflush{#1}} % but drop this if content of element is 'Skip Title' \stopxmlsetups \startxmlsetups xml:p \xmlflush{#1}\par \stopxmlsetups \starttext \xmlprocessbuffer{main}{test}{} \stoptext Expected outcome: Title 1 Hello world. Hello world! Title 2 Hello world? Title 3 Hello :-)

The next does not deserve a price for elegance, but because \xmlflush is expandable (this is its best feature, I think!) you can use the traditional tex toolkit macros: \startxmlsetups xml:h3 \doifinstringelse{Skip title}{\xmlflush{#1}} {} {\subject{\xmlflush{#1}}} \stopxmlsetups I'm fairly certain that there are nicer solutions, however. Best wishes, Taco

Thanks Taco, this works, I owe you a beer at next year's ConTeXt meeting! I'm still interested in a 'proper' xml (= non-TeX) based solution, anyone? Jelle

\startxmlsetups xml:h3 \xmldoifnot {#1} {[text()='Skip title']} { \subject{\xmlflush{#1}} } \stopxmlsetups or: \xmlsetsetup {main} {h3[text()='Skip title']} {-} ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
