How can I use regex for URL validation?
You can use regex to check if a URL is valid by matching it against a specific pattern. Would you like to see an example?
Yes, please provide an example regex pattern for validating URLs.
Here's a simple regex pattern for URL validation: ^(https?://)?(www\.)?([a-zA-Z0-9-]+\.)+[a-zA-Z]{2,6}(/.*)?$
. This checks for HTTP/HTTPS and optional www.
What does each part of that regex pattern mean?
Sure! The pattern checks for optional 'http://' or 'https://', optional 'www.', followed by the domain name and a top-level domain. The last part allows for optional paths.
