Bookmark sets of lines that does not meet criteria

I’ve found out a simple example of the advantage of the conditional feature !

Let’s suppose that you have a particular tag <guy> and that you want :

To delete the starting tag <guy> with, both, its leading and trailing space chars
To delete the ending tag </guy> with its leading space char, only

The simple and obvious solution is :
- SEARCH \x20<guy>\x20|\x20</guy>
- REPLACE Leave EMPTY
Now, this shorter regex S/R, with a conditional expression, related to group 1, is :
- SEARCH \x20<(/)?guy>(?(1)|\x20)
- REPLACE Leave EMPTY

I verified that the suppression of 500,000 starting tags and 500,000 ending tags, in one step, take the same time, whatever the regex syntax used !
