I need an regex, which will match the next urls:

(http|https)://(www)<my domain here>
(http|https)://(www)<my domain here>/page1
(http|https)://(www)<my domain here>/page1/.../
(http|https)://(www)<my domain here>/page1/...?a=b
(http|https)://(www)<my domain here>/page1/...?a=b&c=d...

I have one regex, but I don't know how to edit it

^(http:\/\/|https:\/\/)?(www.)?([a-zA-Z0-9]+).[a-zA-Z0-9]*.[a-z]{3}.?([a-z]+)?$

You can use the following:

^(http:\/\/|https:\/\/)?(www.)?([a-zA-Z0-9]+).[a-zA-Z0-9]*.[a-z]{3}.?([a-z]+)?(\/[a-z0-9])*(\/?|(\?[a-z0-9]=[a-z0-9](&[a-z0-9]=[a-z0-9]*)?))$

For a specific domain name:

^(http:\/\/|https:\/\/)?(www.)?example\.com(\/?|(\?[a-z0-9]=[a-z0-9](&[a-z0-9]=[a-z0-9]*)?))$

Edit: Validate domain and get Url:

(http:\/\/|https:\/\/)?(www.)?example\.com\S*

you don't understand me, I want to get only urls with specific domain name, e.g.: example.org... Where I should put "example.org" in your regex?
@Sevak.Avet updated the answer.. i thought you wanted validations for /page1/...?a=b.. etc.. :P
I mean, I want to get full URL with specific domain :) I want to validate only domain, but get full URL

Try this:

Try use this:

^(http|https):\/\/(www).([a-z\.]*)?(\/[a-z1-9\/]*)*\??([\&a-z1-9=]*)?

The explanation I get in site Regular expressions 101.
