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 //
I have worked on it extensively and here is the result:
(?i)(?<scheme>http|https|ftp|sftp|sip|sips|file):\/\/(?:(?<username>[^`!@#$^&*()+=,:;'"{}\|\[\]\s\/\\]+)(?::(?<password>[^`!@#$^&*()+=,:;'"{}\|\[\]\s\/\\]+))?@)?(?:(?<ipv4>((?:(?:25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(?:25[0-5]|2[0-4]\d|1?\d\d?)))|\[(?<ipv6>(?i)(?:[\da-f]{0,4}:){1,7}(?:(?<ipv4_in_ipv6>(?:(?:25[0-5]|2[0-4]\d|1?\d\d?)\.){3}(?:25[0-5]|2[0-4]\d|1?\d\d?))|[\da-f]{0,4}))\]|(?:(?<sub_domain>[^\s~`!@#$%^&*()_+=,.?:;'"{}\|\[\]\/\\]+\.)*(?<domain>[^\s~`!@#$%^&*()_+=,.?:;'"{}\|\[\]\/\\]+)(?<tld>\.[^\s~`!@#$%^&*()\-_+=,.?:;'"{}\|\[\]\/\\0-9]{2,})))+(?<port>:\d+)?(?:\/(?<path>\/?[^\s`@#$^&=.?"{}\\]+\/)*(?<file>[^\s`@#$^&=?"{}\/\\]+)?(?<query>\?[^\s`#$^"{}\\]+)*(?<fragment>#[^\s`$^&=?"{}\/\\]+)?)?
So, in your case, there is just a need to get the group contains the path and add the word you like, i.e. videoplay. To be more specific, I am talking about this:
(?:\/videoplay(?<path>\/?[^\s`@#$^&=.?"{}\\]+\/)*(?<file>[^\s`@#$^&=?"{}\/\\]+)?(?<query>\?[^\s`#$^"{}\\]+)*(?<fragment>#[^\s`$^&=?"{}\/\\]+)?)?
var subject =
'<link rel="shortcut icon" href="https://cdn.sstatic.net/Sites/stackoverflow/img/favicon.ico?v=ec617d715196"><link rel="apple-touch-icon" href="https://cdn.sstatic.net/Sites/stackoverflow/img/apple-touch-icon.png?v=c78bd457575a"><link rel="image_src" href="https://cdn.sstatic.net/Sites/stackoverflow/img/apple-touch-icon.png?v=c78bd457575a">';
var re=/\"[a-z]+:\/\/[^ ]+"/m;
document.write(subject.match(re));You can try this
/\"[a-z]+:\/\/[^ ]+/
Usage
if (/\"[a-z]+:\/\/[^ ]+/m.test(subject)) { // Successful match } else { // Match attempt failed }
for new Googlers, use JavaScript web api URL at any environment:
new URL('your url string').pathname
Even though the answers using language features are good, here is one more way to split URL to components using REGEXP:
^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\\?([^#]*))?(#(.*))?
|| | | | | | | |
12 - scheme | | | | | | |
3 4 - authority, includes hostname/ip and port number.
