OK! Thanks MadeInGermany!
This changes the deal quite a bit! But it gives me a better view of the substitution being made!

I got:
Code:
substitution command / text that is going to be substituted / substitution / print

Now what I'm not sure to grasp is how it manages to stop at the
Quote:
"
? Is that thanks to the
Quote:
Quote:
[^"]*
is any consecutive number of non-quote characters
thingy? Does the deal go like: Start at
Quote:
href="
up to the next quote character?

Also why are there
Quote:
.* .... .*
in the structure?
s/.*href="\([^"]*\).*/\1/p
