HackerRank Detect HTML Tags, Attributes and Attribute values solution in Python

HackerRank Detect HTML Tags, Attributes and Attribute values solution in python – In this Detect HTML, Tags Attributes and Attributes values problem in python programming. You are given an HTML code snippet of N lines. Your task is to detect and print all the HTML tags, attributes and attribute values.

Print the detected items in the following format:

Tag1
Tag2
-> Attribute2[0] > Attribute_value2[0]
-> Attribute2[1] > Attribute_value2[1]
-> Attribute2[2] > Attribute_value2[2]
Tag3
-> Attribute3[0] > Attribute_value3[0]

The -> symbol indicates that the tag contains an attribute. It is immediately followed by the name of the attribute and the attribute value.
The > symbol acts as a separator of attributes and attribute values.

If an HTML tag has no attribute then simply print the name of the tag.

Note: Do not detect any HTML tag, attribute or attribute value inside the HTML comment tags (<!-- Comments -->). Comments can be multiline.
All attributes have an attribute value.

Input Format

The first line contains an integer N, the number of lines in the HTML code snippet. The next N lines contain HTML code.

import re
num_lines = input()
lines = [raw_input() for i in xrange(num_lines)]
text = ' '.join(lines)
text = re.sub(r'<!--.*?-->', '', text, flags=re.DOTALL)

from HTMLParser import HTMLParser
class Parser(HTMLParser):
    def handle_starttag(self, tag, attrs):
        print tag
        for name, val in attrs:
            print '->', name, '>', val

Parser().feed(text)

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(tag)
        [print('-> {} > {}'.format(*attr)) for attr in attrs]

html = ‘n’.join([input() for _ in range(int(input()))]) parser = MyHTMLParser() parser.feed(html) parser.close()
