Keep only numeric filed of string

Hello guys,

I’m trying to get a phone number from : “tél : 01 49 30 32 05 fax : 01 49 41 21 15 Dr J. kkkk Dr P. jjjjj”

my methode is to keep only the numeric fields and the string “:” for ex: " : 01 49 30 32 05": via item.Replace("[^+0-9]", “”); but this regex need to be correted in order to kepp olso “:” (any idea?)

and use a Substring(0, 10); to get the phone number,

any idea

test this:
(?= )( : \d{2} \d{2} \d{2} \d{2} \d{2} )(?<= )

in fact i had found the solution
