XML 1 - Find the Score Answer

This Python program is designed to parse an XML document and calculate the total number of attributes it contains. It uses the xml.etree.ElementTree module to parse the XML and traverse the tree structure of the document.

Here is the XML 1 - Find the Score Answer HackerRank solution using CodeRankGPT:

The solution works by defining a recursive function, get_attr_number, which takes an XML node as input. It first counts the number of attributes in the current node, then iterates over each child node. If the child node has children, the function calls itself recursively on the child node. If the child node has no children, it counts the number of attributes in the child node. The total number of attributes is then returned. The main part of the program reads the XML document from standard input, parses it into an ElementTree object, gets the root of the tree, and then calls the get_attr_number function on the root.


import sys
import xml.etree.ElementTree as etree

def get_attr_number(node):
    total = len(node.attrib.keys())
    for child in node:
        if child:
            total += get_attr_number(child)
        else:
            total += len(child.attrib.keys())
    return total

if __name__ == "__main__":
    sys.stdin.readline()
    xml = sys.stdin.read()
    tree = etree.ElementTree(etree.fromstring(xml))
    root = tree.getroot()
    print(get_attr_number(root))
