Instance 1 (the information page has pagination, and a simple paging regular expression is used ):


Instance 2 (there is no paging on the information page, so the paging regular is blank ):


Instance 3 (there is no paging on the information page, so the paging regular is blank, the image is an absolute address, so the image address prefix is blank ):
