HackerRank HTML Parser – Part 1 solution in python

In this HTML Parser – part 1 problem You are given an HTML code snippet of N lines. Your task is to print start tags, end tags, and empty tags separately.

Problem solution in Python 2 programming.

from HTMLParser import HTMLParser

# create a subclass and override the handler methods
class MyHTMLParser(HTMLParser):
    def handle_starttag(self, tag, attrs):
        print "Start :", tag
        for attr in attrs:
            print "->", attr[0], ">", attr[1]
    def handle_endtag(self, tag):
        print "End   :", tag
    def handle_startendtag(self, tag, attrs):
        print "Empty :", tag
        for attr in attrs:
            print "->", attr[0], ">", attr[1]

N = int(input())
parser = MyHTMLParser()

for i in xrange(N):
    parser.feed(raw_input())

Problem solution in Python 3 programming.

# Enter your code here. Read input from STDIN. Print output to STDOUT
from html.parser import HTMLParser
class MyHTMLParser(HTMLParser):
    def handle_starttag(self, tag, attrs):        
        print ('Start :',tag)
        for ele in attrs:
            print ('->',ele[0],'>',ele[1])
            
    def handle_endtag(self, tag):
        print ('End   :',tag)
        
    def handle_startendtag(self, tag, attrs):
        print ('Empty :',tag)
        for ele in attrs:
            print ('->',ele[0],'>',ele[1])
            
MyParser = MyHTMLParser()
MyParser.feed(''.join([input().strip() for _ in range(int(input()))]))
