It looks like LogFusion is matching the highlight rule to the whole line, including the line number at the beginning (which isn't actually in the log file). I'll add this to our list to fix up, and I'll also add your feature requests :)

But, then all rows, also the ones starting with a date, was highlighted.

I have, however, found a workaround:
By adding a highlighting for all as the last rule and then another rule just above it in the list, for rows starting with a date, resetting the hightlighting.
Then using these two rules together gives the wanted result.

Btw: I have a couple of feature suggestions:
1. An option on Highlighting rules to Invert Match (i.e. Not highlighting matches, but all rows not matched)
2. An description field for the rule (for comments, or to replace the actual rule in the dropdown - especially useful for regex rules) ]]> RE: Regex for highlighting rows that do not start with a date stamp https://www.logfusion.ca/Discussions/View/regex-for-highlighting-rows-that-do-not-start-with-a-date-stamp/?ID=3e9094e1-6ce3-4291-bf23-16fb02788583#2 Fri, 05 Jul 2013 14:22:18 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/regex-for-highlighting-rows-that-do-not-start-with-a-date-stamp/?ID=3e9094e1-6ce3-4291-bf23-16fb02788583#2 LogFusion I've tested that RegEx string here, and it seems to work. After you added it in the highlight settings, did you then enable it on the log using the Highlight drop-down on the toolbar? ]]> Regex for highlighting rows that do not start with a date stamp https://www.logfusion.ca/Discussions/View/regex-for-highlighting-rows-that-do-not-start-with-a-date-stamp/?ID=3e9094e1-6ce3-4291-bf23-16fb02788583 Fri, 05 Jul 2013 13:38:41 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/regex-for-highlighting-rows-that-do-not-start-with-a-date-stamp/?ID=3e9094e1-6ce3-4291-bf23-16fb02788583 LogFusion I've tried to create rule for highlighting rows that do not start with a date stamp (e.g "2013-07-05").
I've created a regex that works in RegexBuddy and seems to work in the Edit Highlight dialogue in the Highlight Testing textbox:
But when applied on the log, this does not work:

(?m)^(?!(\s*\d{4}-\d{2}-\d{2}.*$)).*$

Any idea why? ]]>
