Regular Expression help with search ranges and replacing

[Lloyd Goss]

How do you carry over a result of a range like [0-9] to the replace side.

So that when "Jn[0-9][0-9]_"  finds "Jn12_" the 12 (or and pair of digits) carries over to the replacement.

My goal is to replace all occurrences of the ending "_" with a "."

So "Jn01_" becomes "Jn01." 

So "Jn12_" becomes "Jn12." 

Thanks in advance.

'Capture buffers' are the answer.

Find:

(Jn[0-9][0-9])_

Replace with

\1.

Left bracket starts the capture, right bracket finishes it, \1 references what was between the brackets.  You can have more than 1 set of brackets, then use \2 for the 2nd, etc.

Try capturing your original as ("Jn\d+)_(")

And replace with \1.\2 

This should replace the _ with a . (full stop or is that "period" to you?) in both cases
