At least not with the changes I made - I disabled all built-in string detection and all built-in comment detection except for the /* ... */ style comments - I left those in because I couldn't work out how to check for multi-line constructs. Basically that means that /* and */ are detected before any other comment and string detection, so even inside a string or regex they will be interpreted as comment markers. As a work around, you can escape the * character, which should not have any effect on the code: getElementsByXPath('.//\*' + cond, element) I'm going to try and find a better solution, but don't hold your breath :-) Hey Michael,

getElementsByXPath(’.//\*’ + cond, element)

That said, if you're interested, there's one expression in the latest version at http://prototypejs.org/assets/2008/1/25/prototype-1.6.0.2.js that causes some mis-hilighting. If you look at line 4160, there's an xpath expression involving // that causes the rest of the file to be highlighted as a comment. Still, much much better than sending Emacs into some sort of tight loop! Many thanks! Mike.
