How to use regex to remove non-numeric characters surrounding numeric characters

Question

I have the following string and need to match the continuous numeric part. i.e. matching will fail if a non-numeric character is in the middle of the numeric part

I know I can write a for loop a iterate through each character, but is it possible with regex alone?

the numeric part 00000 will match in these

AAA00000BBB
00000BBB
AAA00000

these will not match

AAA00X00BBB
00X000

This one should do the job:

^\D*(\d+)\D*$

Explanation:

^       : begining of string
  \D*   : 0 or more non digit
  (\d+) : 1 or more digit, captured in group 1
  \D*   : 0 or more non digit
$       : end of string
