What should the correct regular expression look like to search for a hostname?

Question

Java

Groovy

def URL = "sdfgsdfg https://inclouds.bizmail.ru hgfghfhgfhgf gfhgf"

print(URL.findAll(/\/\/(\w+.\w+.\w+)/))

Returns:

[//inclouds.bizmail.ru][[://inclouds.bizmail, inclouds.bizmail]]

But I need inclouds.bizmail.ru.

How to do it right?

Answer 1

At least the dot is not escaped, which means it is "any character". But this is so, by the way.
And the answer is:

def URL = "sdfgsdfg https://inclouds.bizmail.ru hgfghfhgfhgf gfhgf"

print(URL.findAll(/(?<=:\/\/)[\w\d.]+/))

Although it is far from perfect. More precise conditions of the problem will help to improve it.

Answer 2

print(URL.findAll(~(?=https://)[^\s]+~))
