Question

i’m working for a long time to get an regexp string – but without any success.
Hope, to get some help here.
There are strings in the following format:

G/20/EU (picture)/europe 21/

or

/House/200 hits/real estate

or

color/red-green/dark blue/orange/321

Global rule: split the text on the characters / ( )
So the following regexp works: ([/()])
But I also need to remove/split on single numbers. Here: 20 and 321, but NOT on 21 (which is one phrase with “europe 21”) or 200 (which is one phrase with “200 hits”)

Sometimes the strings starts with an / or ends with an /, sometimes not. Numbers can occur at the beginning, at the end or in the middle of the string.

The results should be simple words or phrases like:

G
EU
picture
europe 21
House
200 hits
real estate
color
red-green
dark blue
orange

Have anyone an idea, how an regexp could look like?

Thank you

If your regex flavour does have look ahead and behind, you can try this:

[/()]|(?<=\/|^)\d+(?=(?:\/|$))

See it here on Regexr.

This will check for a series of digits, where there is a / or the start of the row ^ before, and a / or the end of the row $ behind.
Or for your part
