不以特定单词结尾的正则表达式

Question

I need to have a regex which matches the following -

/drama/uk
/drama/uk/
/drama/us
/drama/us/
/drama/fr
/drama/fr/

but should not match the following -

/drama/uk-uk
/drama/uk-uk/
/drama/us-us
/drama/us-us/
/drama/fr-fr
/drama/fr-fr/

So far I have managed to get the first par working like this

/\/drama\/\uk|uk\/|us|us\/|it|it\/|fr|fr\/$/

But I don't know how to get the second part working. Can any one help please

Answer 1

You could use an anchor to start the string ^ , then match /drama/ and use an alternation with a non capturing group to list all the alternatives.

The slash at the end can be optional.

^\/drama\/(?:uk|us|fr)\/?$
