Regex to slect a string not having a certain word followed by a certain set of words

Question

I am trying to find a regex that will do the following

Return true if a string ends with jaxws.managed but does not contain delegate.

eg

abc/delegate/xyz/jaxws/managed should return false, while

abc/def/xyz/jaxws/managed should return true

I tried using the regex

([^(delegate)])+([a-z]*[\\/]jaxws[\\/]managed[\\/])+

but it fails . Any help is much appreciated

Answer 1

Assuming Java regex,

^(?!.*delegate).*jaxws/managed$

Answer 2

You should specify what regex engine you're using.

Nevertheless...

return false if it contains "delegate" anywhere: /delegate/; -> return false

if we don't return, and it ends in "jaxws/managed", return true: /jaxws\/managed$/; -> return true

if you're using Perl, I suggest applying m{} instead of // to avoid the "leaning toothpick syndrome". Refer to perlre for more information.
