regex getting number from a string
Hello,
I need help to make some regex.
I have header as below:
User-to-User: 04C80B2A21353837373030313031FA08000100A652D7EF78;encoding=hex
Digits marked by red is the telephone number which I need to get from these header and put it to From header. Of course this number can be different (only prefix 58770 is constant).
Also in this string constant is 04C80B2A213 and FA08000100A.
How should regex looks like to get this number from the string?
