I get the id from all the links except the one with the shareId=xxxxxxxxxxx. I modified my original regex to the following below and still not getting the id from the link with shareId=xxxxxxxxxxx. Any help will be greatly appreciated.

(?:|shareId=)(\/[\d] )

CodePudding user response：

You can use this regex:

'''(?:\/|shareId=)\d (?!.*\/)'''g

It matches either a slash / or shareId= followed one or more digits.

It then adds an extra check that there are no more slashes on that line - this way slashes in names won't match.

There are working answers given already, but I want to suggest an elegant-looking solution:

([=/][\d] )

The first set checks for either '=' or '/' symbol. See https://regex101.com/r/9uNJZ1/1
