I have the following sequence:
3531399402
It has 10 numbers, with this regex I can list these occurrences:
^\d{10}$
I'm using a text editor and I need to give a replace on those instances and insert a 0 before getting like this:
03531399402
How can I do it?
You must enter a capture group. Home So you can identify replace through the group and use it again with what you want to insert. Home I suggest you try changing your regex to:
^(\d{10})$
And use for replace:
0$1
This indicates that replace must be done by entering 0 and capture group 1 which in this case are the 10 digits you mentioned in the question.
