A regular expression does not necessarily have only one match. This can be done through match. nextmatch to try the following match. All groups in the regular expression can be obtained through the groups attribute of match. The Grou

This is the child pattern (a child match), by default, in addition to combining multiple characters into a whole, and storing the parentheses, the part of the expression enclosed in a temporary buffer for subsequent regular expression calls. In this example above, we do not need to call later. So how do you block out this subexpr
