What RegEx to use to include all subroutes except for specific urls-CodePudding

I'm terribly at regex and I could use some help in building a regular expression so that I can target all subroutes on a specific domain and at the same time exclude a couple of specific subroutes.

The regex is to be used in JavaScript (as page targeting within the Optimizely software).

Should allow:

www.mydomain.com/**/*
www.mydomain.com/foo/**/*

Should not allow

www.mydomain.com/foo/bar/**/*
www.mydomain.com/baz/**/*

The part I am most struggling with is allowing everything, also allowing everything ending with /foo/... except when it is ending with /foo/bar/..., while also excluding anything ending with /baz/....

Any help is much appreciated, thank you in advance!

CodePudding user response：

You can use a negative lookahead assertion to exclude specific patterns:

^www\.mydomain\.com\/(?!(?:foo\/bar|baz)\/).*\/.*

CodePudding user response：

Use this (www.mydomain.com\/)(([a-z] \/)*(foo\/))?\*\*\/\*. It should work.

It's working in this scenario:

`www.mydomain.com/**/*`
or
`www.mydomain.com/<any params may or may not be>/foo/**/*`

Code:

var regx = /(www.mydomain.com\/)(([a-z] \/)*(foo\/))?\*\*\/\*/g;
ar = ['www.mydomain.com/**/*', 'www.mydomain.com/foo/**/*','www.mydomain.com/foo/bar/**/*','www.mydomain.com/baz/**/*']
regx.test(ar[0]) // true
regx.test(ar[1]) // true
regx.test(ar[2]) // false
regx.test(ar[3]) // false
