I am transferring an Android SMS database to my iPhone manually without restoring. Because of the number format of +1562... the iPhone does not recognize the format and creates a new text thread.
I am trying to change +15629876543 to 5629876543 and +17114747474 to 7114747474, and so on.
There are thousands more numbers ranging in size. Any other number that has more than or less than 10 digits, should be untouched.
This seems to be a step in the right direction:
grep -P '(?<!\d)\d{4}(?!\d)' file
retrieved from How to grep for groups of n digits, but no more than n?
Here is a sample of the XML file (EDIT: I added a root element named <root> to make the XML well-formed).
