Regex pattern for String not ending in a sequence

Question

I am trying to find all strings not ending with the sequence -6X. What i'm trying to do is compare the value of an xml tag with a sequence. If it matches then do some stuff. However I am unable to do so. I want to achieve this without any lookaheads or lookbehinds.

I've tried using .*[^-6X] However this does not work for strings ending in - or -5 . I want to ignore strings ending in -6X only and every other pattern should work. Thanks in advance for your help

what language/tool do you use? Negative lookaheads may help you but they are not supported in all regex flavors — mrzasa, Mar 22 '18 at 09:05
negative lookaheads are not supported I think. i am using this pattern in xml to compare the value of a tag with a string. — Sr7, Mar 22 '18 at 09:06
You don't need a regex, just test `string.endsWith(...)` or whatever your language has. — Mat, Mar 22 '18 at 09:06

This matches Strings NOT ending with -6X:

.*?([^-]..|.[^6].|..[^X])$
