For those who are new to Regex, I would advise you to have a quick look at for more information and also to give you a platform to test your own scripts.


Format 07999999999 into +447999999999

Oracle provides some guidelines on regex but you will need to get your head around it first before you can make it work for you.
The example below picks up the number in the source field and breaks it into different components that allow it to be manipulated

  • Source field+1111234567891
  • Regular expression to find^(\\+[\\d]{1,3}|0)?(\\d{3})(\\d{3})(\\d{4})$
  • Regular expression replace($1) $2 $3-$4
  • Destination field result(+111) 123 456-7891

Using Regular Expression in Eloqua Contact Washing Machine

The key is to break the number in the source field into bite-size chunks then write an expression to alter each of the sections.

  • Source field07999999999
  • Regular expression to find([\d]{1})(\d{10})$
  • Regular expression replace+44$2
  • Destination field result+447999999999

The source text has 11 characters and the goal is to split it into two sections. ([\d]{1}) isolates the first character (0) and the (\d{10}) isolates the rest of the numbers.

  • ([\d]{1}) = 0
  • ([\d]{10}) = 7999999999
  • $1$2 = 07999999999

Final Output

Final step is to replace the $1 part with the +44

+44$2 = +447999999999
