We noticed that no class = "1", class = "2", class = "3 ",... it is regular, but the previous labels are not regular, sometimes span, and sometimes div. what I want is to use php to write regular expressions to get class = "1 ", class = "2", class = "3 ",... the regular expression is hard to learn. I have tried it for half a day and cannot write it out! Share: More
