Code fragment 6.5 is given below

if tag [1:] != S.pop():

3. (30 points) In Code Fragment 6.5 (in the textbook, also copied below), we assume that opening tags in HTML have form , as with

. More generally, HTML allows optional attributes to be expressed as part of an opening tag. The general form used is ; for example, a table can be given a border and additional padding by using an opening tag of . Modify Code Fragment 6.5 so that it can properly match tags, even when an opening tag may include one or more such attributes. 3.
