Write a program that will take HTML as input and will output the number of HTML tags in the string. The program should use regular expressions to count the number of elements nested at each level. For example, the HTML:
hi
has a p element (nesting level 0—i.e., not nested in another tag) and a strong element (nesting level 1). For simplicity, use HTML in which none ofthe elements contain nested elements of the same type—for example, a table element should not contain another table element. This solution requires a regular expression concept called a back reference to determine the start and end tags of an HTML element. To find these tags, the same word must appear in the start and end tags. A back reference allows you to use a previous match in the expression in another part of the regular expression. When you enclose a portion of a regular expression in parentheses, the match for that subexpression is stored for you. You can then access the result of that expression using the syntax \digit, where digit is a number in the range 1–9. For example, the regular expression ^(7*).*\1$ matches an entire string that starts and ends with one or more 7s. The strings "777abcd777" and "7abcdef7" both match this regular expression. The \1 in the preceding regular expression is a back reference indicating that whatever matched the subexpression (7*) should also appear at the end of the string. The first parenthesized subexpression is back referenced with \1, the second is back ref- erenced with \2, etc. You’ll need a recursive function so that you can process the nested HTML elements. In each recursive call, you’ll need to pass the contents of an element as the string to be processed in that call—for example, the contents of the p element in this example’s HTML would be hi Use parentheses to store the content that appears between the start and end tags of a string that matches your regular expression. This value is stored in the match_results object and can be accessed using the [] operator on that object. As with back references, the subexpression matches are indexed from 1 to 9. What will be an ideal response?
