Issue/Introduction

I'd like to have a regular expression that detects:

- 3 or more numbers within a block

OR

- any character 3 numbers any character

OR

- any character 3 numbers any character endofline

Then to replace the block with the text : {number}

 

EXAMPLE#1:

/cc/api/policy/SDFVRT0662341293-1/risk/GCEE598LB/claimTypes

to be normalized as

/cc/api/policy/{number}/risk/{number}/claimTypes

EXAMPLE#2:

/api/autore/flaim/moto/et535yj

normalized it as

/api/autore/flaim/moto/{number}

EXAMPLE#3:

/srv/brww/caucion/cust/00010122C 

normalized it as

/srv/brww/caucion/cust/{number}
