Hi all

Consider the following string

'35=_-235-b-35=35-35=2-135=a-35=123-235=2-35=a-53=1-53=a-553=b'

I'd like to extract everything that matches 35= followed by 1 or 2 characters. What I came up with is the following regex

\d[35]=[A-Za-z0-9]{1,2}

The problem is the character set [35] matches both 35= and 53=. How can I achieve an exact match for a character set?

Any suggestions, or different approaches are very much appreciated!
