Regular expression example

Using the tags list of the above picture.

If you want add a prefix to all tags you don’t need to use regular expression:

	Find what:	MRTU
	Rename with	PLC01_MRTU

But if you want add a postfix, you need to use a regular expression:

	Find what:	MRTU(.*)
	Rename with	MRTU\1_PLC01

Where

	(.*)	is meaning any sequence of characters
	\1	is a copy of the first sequence of characters enclosed by (...) found inside the search string

If you want to remove a prefix, you need to use regular expression:

	Find what:	^(prefix)
	Rename with	empty

For example, the filter in the following figure:
