Currently, I am attempting to create a regular expression that can identify URLs like the following:
https://www.youtube.com/playlist?list=PLBOh8f9FoHHjOz0vGrD20WcTtJar-LOrwHowever, I do not want it to match URLs such as:
https://www.youtube.com/watch?v=4jduuQh-Uho&list=PLBOh8f9FoHHjOz0vGrD20WcTtJar-LOrw&index=3I attempted to create one that identifies if there is a list= but no v=, yet it seems to match both types of URLs.
Check out this method for achieving the desired result using regex and the specific pattern below:
^(?!.*\?.*\bv=)https:\/\/www\.youtube\.com\/.*\?.*\blist=.*$
// scenario one, a URL that fails because of a v= query parameter
var url1 = 'https://www.youtube.com/watch?v=4jduuQh-Uho&list=PLBOh8f9FoHHjOz0vGrD20WcTtJar-LOrw&index=3';
console.log(/^(?!.*\?.*\bv=)https:\/\/www\.youtube\.com\/.*\?.*\blist=.*$/.test(url2));
// scenario two, a URL that passes due to list= and absence of v=
var url2 = 'https://www.youtube.com/playlist?list=PLBOh8f9FoHHjOz0vGrD20WcTtJar-LOrw';
console.log(/^(?!.*\?.*\bv=)https:\/\/www\.youtube\.com\/.*\?.*\blist=.*$/.test(url2));The pattern employs a negative lookahead to exclude URLs containing a v= query parameter, while still allowing URLs with a list= query parameter to match.
Give this a shot:
(?:https?:\/\/)?(?:youtu.be\/|(?:www\.|m\.)?youtube.com\/(?:playlist|list|embed)(?:\.php)?(?:\?.*list=|\/))([a-zA-Z0-9\-_]+)
If you need to extract a video URL from a given string of text, you can use regular expressions.
^.*(youtu.be\/|list=)([^#\&\?]*).*
Here is a sample regex pattern: https://regex101.com/r/CWYDyf/1
I believe utilizing a wildcard and the correct regex pattern could be '.\?list=.*'
Have you thought about searching for 'playlist' instead of 'list'? It's only in one of the links.
Another option is to filter out URLs that don't have the word 'watch':
(^https:(?:(?<!watch).)*?$)
(replace ^ with the starting character sequence and $ with the ending character sequence) If your characters are ", you could try something like this:
("https:(?:(?<!watch)[^"])*?")
where [^"] will match any character except "
