I want to check if URL is valid to match below pattern.
https://xxx.abc.com/yyy/?&p=1000/1001
How can i write the Regex to achieve?
Expected:
Starts with domain 'https://xxx.abc.com', 'xxx' could be any name of sub-domain, 'abc.com' should be fixed value.
Path /yyy could be any path, even sub-path should be allowed. https://xxx.abc.com/yyy/?&p=1000/1001
?&p=1000/1001 should be ok with '\?(\&)?p=\d+/\d+'
Since you didn't specify any restrictions on xxx or yyy, I'm going to assume they should conform to something reasonable such as "1 or more alphanumeric characters or a dash/hyphen" or in regex: [a-bA-B0-9\-]+ feel free to adjust that to anything else in the regex:
^https:\/\/[a-bA-B0-9\-]+\.abc.com/[a-bA-B0-9\-]+\/\?(\&)?p=\d+/\d+$
breaking it down:
^ in the start and the $ in the end are important because they make sure the regex matches the entire string you pass it (^ binds to the beginning of the input string and $ binds the end) without those, you might match any string that contains the URL as a substring[a-bA-B0-9\-]+ parts, as mentioned above match any sequence of alphanumeric or - characters. Note that if you are using a regex framework that allows you to run the regex case insensitive (e.g. a perl/javascript like regex /regex/i or in c# using RegexOptions.IgnoreCase) you can safely change this to [a-b0-9\-]+/https:\/\/[a-z0-9]+\.abc\.com\/.*\?(\&)?p=\d+\/\d+/i
Try with this: ^https:\/\/\w+\.abc\.com\/[\w\/-]+\?\&?p=\d+\/\d+$
You can divide your regex into two groups :
^(https:\/\/[a-z0-9]+\.abc\.com)(\/.*\?\&?p=\d+\/\d+)$
1 - The first group starts with domain https://xxx.abc.com
2 - The second group is the sub-path like /yyy/?&p=1000/1001
