Bob, Thanks for the idea. Our schema uses RelaxNG, though, so it would be a big change to switch to XSD. The text matching enhancement that was requested would not, by itself, be enough motivation.

Leif, Ph.D. rleif@rleif.com<mailto:rleif@rleif.com> From: oXygen-user <oxygen-user-bounces@oxygenxml.com<mailto:oxygen-user-bounces@oxygenxml.com>> On Behalf Of Amanda Galtman Sent: Friday, March 9, 2018 10:47 AM To: oxygen-user@oxygenxml.com<mailto:oxygen-user@oxygenxml.com> Subject: [oXygen-user] CSS background color based on text matches Hi, We've had a request from an author to make the formatting in the Author view indicate when the text of a certain element type does not match the text of something else found inside the same topic. I can do this via Oxygen CSS, but I am concerned that the processing slows down the opening of large documents. I'm not convinced that CSS is a good way to address the underlying requirement about helping authors detect when something does not have a textual match as expected (e.g., maybe Schematron or a build warning would be more appropriate). Before I give up, though, I wanted to see if anyone had specific ideas or techniques I might have overlooked. Here's an example of variations I tried that work too slowly in large documents, just to give you the flavor. /* true => 255*1 => white * false => 255*0 => yellow */ refentry[role="function"] literal { background-color: oxy_xpath( "concat('rgb(255,255,', 255 * number(. = ancestor::refentry//term or .='') , ')')", evaluate,dynamic-once); } Alternate: refentry[role="function"] literal { background-color: oxy_xpath( "if (exists(text()) and not(some $n in ancestor::refentry/refsect1[@role=('inputs','outputs')]//term satisfies string($n)=.)) then ('yellow') else ('')", evaluate,dynamic-once); } Thanks, Amanda
