Regex URL Path from URL


Question

I am having a little bit of regex trouble.

I am trying to get the path in this url videoplay.

http://video.google.co.uk:80/videoplay?docid=-7246927612831078230&hl=en#hello

If I use this regex /.+ it matches /video as well.

I would need some kind of anti / negative match to not include //

Accepted Answer

This expression gets everything after videoplay, aka the url path.

/\/(videoplay.+)/

This expression gets everything after the port. Also consisting of the path.

/\:\d./(.+)/

However If using Node.js I recommend the native url module.

var url = require('url')
var youtubeUrl = "http://video.google.co.uk:80/videoplay?docid=-7246927612831078230&hl=en#hello"
url.parse(youtubeUrl)

Which does all of the regex work for you.

{
  protocol: 'http:',
  slashes: true,
  auth: null,
  host: 'video.google.co.uk:80',
  port: '80',
  hostname: 'video.google.co.uk',
  hash: '#hello',
  search: '?docid=-7246927612831078230&hl=en',
  query: 'docid=-7246927612831078230&hl=en',
  pathname: '/videoplay',
  path: '/videoplay?docid=-7246927612831078230&hl=en',
  href: 'http://video.google.co.uk:80/videoplay?docid=-7246927612831078230&hl=en#hello' 
}

In case if you need this for your JavaScript web-app: the best answer I ever found on this topic is here. Basic (and also original) version of the code looks like this:

var parser = document.createElement('a');
parser.href = "http://example.com:3000/pathname/?search=test#hash";

parser.protocol; // => "http:"
parser.hostname; // => "example.com"
parser.port;     // => "3000"
parser.pathname; // => "/pathname/"
parser.search;   // => "?search=test"
parser.hash;     // => "#hash"
parser.host;     // => "example.com:3000"
