Anyone knows the Regexp for AS3 to get the domain name from URL? E.g: "http://www.google.com/translate" will get "http://www.google.com"

  • If you don't care about TLD with double endings (co.uk, co.jp etc) then check http://stackoverflow.com/questions/863297/regular-expression-to-retrieve-domain-tld or google for "RegExp tld" – Mikael Svenson Aug 07 '10 at 18:29

There's is a very complete utility class for dealing with URIs in as3corelib. Perhaps you might want to use this instead of rolling your own.

import com.adobe.net.URI;
var uri:URI = new URI("http://www.google.com/translate");
trace(uri.authority); // traces www.google.com

This should do the work: http(s?)://([\w]+\.){1}([\w]+\.?)+ You can try this in GSkinner RegExr

Try this one:

.*\/\/([^\/:]+).*

Surrounds the regexp by the preferred separators, which might depend on language. This diagram explain how it works.

The previous regex provided missed some url types i needed, so for the benefit of googlers, I use

(http://|https://)?(www.)?[A-z]*(.com|.co.uk|.us|.org|.net|.mobi)

in C#

var regexMatch = Regex.Match(input, @"(http://|https://)?(www.)?[A-z]*(.com|.co.uk|.us|.org|.net|.mobi)", RegexOptions.Multiline);

string domain = regexMatch.Value;

See example at RegExr.

You can remove remove "(...)?" parts to stop that part appearing the match, for example to remove the http matching that I require.

Probably not perfect, but works for me. This site is an excellent reference for building up expressions.

Regex to get the domain from the window.location.href property is provided below. Modifications have to made to a regex answer provided previously by OXMO456 to make it correct and accommodate more scenarios.

domainRegex = /(http(?:s?):\/\/(?:[\w]+(?:\.|\:)){1}(?:[\w]+\.?)+)/gi;
