Detect HTML Tags, Attributes and Attribute Values HackerRank Problem

This Python program is designed to parse an HTML string and print out its tags, attributes, and attribute values. It uses the built-in HTMLParser module from Python's standard library to accomplish this task. The user is prompted to input the HTML string, which is then fed into a custom HTML parser.

Here is the Detect HTML Tags, Attributes and Attribute Values HackerRank Problem HackerRank solution using CodeRankGPT:

The solution works by creating a custom HTML parser that inherits from Python's built-in HTMLParser class. This custom parser overrides the handle_starttag and handle_startendtag methods to print the tag name and handle its attributes. The attributes are handled by the handle_attrs method, which iterates over each attribute pair and prints the attribute name and value. The HTML string is read from the standard input, joined into a single string, and then fed into the custom HTML parser.


from html.parser import HTMLParser

class CustomHTMLParser(HTMLParser):
    def handle_starttag(self, tag, attrs):
        print(tag)
        self.handle_attrs(attrs)

    def handle_startendtag(self, tag, attrs):
        print(tag)
        self.handle_attrs(attrs)

    def handle_attrs(self, attrs):
        for attrs_pair in attrs:
            print("->", attrs_pair[0].strip(), ">", attrs_pair[1].strip())


n = int(input())
html_string = "".join(input() for _ in range(n))
customHTMLParser = CustomHTMLParser()
customHTMLParser.feed(html_string)
customHTMLParser.close()
