All right.
Let's see how we can make that.
So let's just start with Mr..
As you can see, all three or all four lines are marked at least the Mr..
And then if I use a dot, you can see that all of them are active as well.
But that's because dot means wildcard or means anything.
So it could be empty space here as well.
So if you want to make sure it's a literal dot you need to use the backslash.
Now the next one is an empty space.
And afterwards we have the name.
So it could be a to Z.
So anything a to Z like that.
So now how do I get Mr. Mueller and Mr. Robertson in there as well.
Well I need to use the Dot again but this time with a question mark.
Because what I'm telling now is there can be a dot or there can be none.
And afterwards we have an empty space.
So here I used the literal empty space to get that.
But you can as well use backslash s because backslash s, if you check it out again says matches any
whitespace character.
And that's what we wanted.
So now all of those names are correct.
And if you want to have a specific amount of characters following, so the name should be at least four
characters, then you can use this quantifier here.
So we are using the quantifier with n being four.
So we say it's at least four characters or four letters.
If you wanted to not only have characters like A to Z in there, but also numbers, for example, then
you could use backslash w.
So backslash w just means it's a.
As you can see here it's a word character.
So a to z a to z 0 to 9 and underscore.
So it's useful for let's say player names or usernames or stuff like that.
And if I want to have multiple characters I can use the plus sign.
So the quantifier plus matches the previous element one or more times.
So let's check it out.
Let's add the plus.
And as you can see now Mr. Panju to Mr. Mueller Mr. Robertson and Mr. G.
All are fully highlighted because.
Well we have said that we want to have one or more characters.
And if you wanted to have zero or more times then we could use a star.
As you can see, the star works here as well because we have more times or more characters.
All right, now it's time for a little challenge.
Find website links.
So we started off already, but now please go ahead and find every website link that's with this structure.
And it doesn't have to be tutorials.
You it should not be a literal name, but it should be generally the structure.
And the structure is, as you can see, Https https or http colon slash slash then w w w dot or not.
Then the name of the domain and the domain and the top level domain, which is EU in this case.
So it's separated by a dot of course as well.
All right.
So please go ahead and try that.
So yes that's it.
Go ahead and try that and I'll see you in the next video.
