I am working with urls. I need to find a regex that catches strings like this:
string/string/ -OR- string/string
But there is an exception. The first string cannot be "brand" nor "category" (but the second can be).
The second forward slash is optional.
So these are valid strings:
string/string-2
string/yes/
string/brand <--- "brand" or "category" can be after the first slash but not before
string/category/ <--- "brand" or "category" can be after the first slash but not before
the-string/hello
the-string/the-string-2/
These are invalid strings:
hello <--- Only 1 string, has to be 2, not good
hello/ <--- Only 1 string, has to be 2, not good
brand/string <--- contains "brand" before the first slash, not good
brand/the-string/ <--- contains "brand" before the first slash, not good
category/string/ <--- contains "category" before the first slash, not good
category/hello <--- contains "category" before the first slash, not good
hey/hello/world <--- Too many strings (3),only 2 needed, not good. ***THIS IS WHERE I AM STUCK***
So far I am trying this:
^(.*\b(?<!\bbrand|categories))/(.*)?
But it is still catching 3 strigs, like this "hey/hello/world", I need only two (string/string -OR- string/string/)
Please help!
