Splunk Search

Can you help me come up with a regex expression which would extract a number from a string?

Path Finder

Hi,

I have a field which produces a value like this example: DB=HR_10_7_3043_TGTHRLIVE
I am trying extract the number and write it in the following way: DB_Version=10.7.3043
How do I get Splunk to cut off before and after the number and then replace the _ with .

Note: The strings before and after the numbers can vary in length, and the number can vary too.

Many thanks,
Sam
