Regex include one but exclude the other

I'm having trouble finding how to write a regular expression to include specific URLs, starting with a specified phrase, excluding another.

We want to include pages that start with:

/womens
/mens
/kids-clothing/boys
/kids-clothing/girls
/homeware

But we want to exclude everything that / sXXXXXXX has in the URL, where X is numbers.

I have written this so far to fit the URLs below, but it behaves very weird. Should I use searches or something else?

\/(womens|mens|kids\-clothing\/boys|kids\-clothing\/boys|homeware).*[^s[0-9]+].*

You are on the right track. A negative result will do this:

"^(?!.*\/s\d+)\/(womens|mens|kids\-clothing\/boys|kids\-clothing\/girls|homeware)\/.*"

^binds the beginning of a line. (?!.*\/s\d+)means it "/sXXXXXXX"cannot appear anywhere on the line, and the rest corresponds to the desired starting markers.

[^s[0-9]+] , [^xyz] . , , "s", "[" "0-9", "]". "s[234[s]".

, , . \/(womens|mens|kids\-clothing\/boys|kids\-clothing\/girls|homeware)\/.*, "/sXXXXXXX". 1 "/homeeware/bathroom/".
