XML2 – Find the Maximum Depth in Python | HackerRank Solution

Hello coders, today we are going to solve XML2 – Find the Maximum Depth HackerRank Solution in Python.

XML2 - Find the Maximum Depth in Python


You are given a valid XML document, and you have to print the maximum level of nesting in it. Take the depth of the root as 0.

Input Format

The first line contains N, the number of lines in the XML document.
The next N lines follow containing the XML document.

Output Format

Output a single line, the integer value of the maximum level of nesting in the XML document.

Sample Input

<feed xml:lang='en'>
    <subtitle lang='en'>Programming challenges</subtitle>
    <link rel='alternate' type='text/html' href='http://hackerrank.com/'/>

Sample Output



Here, the root is a feed tag, which has depth of 0.
The tags title, subtitle, link and updated all have a depth of 1.
Thus, the maximum depth is 1.

Solution – XML2 – Find the Maximum Depth in Python

import xml.etree.ElementTree as etree

maxdepth = 0
def depth(elem, level):
    global maxdepth
    # your code goes here
    if (level == maxdepth):
        maxdepth += 1
    for child in elem:
        depth(child, level + 1)

if __name__ == '__main__':
    n = int(input())
    xml = ""
    for i in range(n):
        xml =  xml + input() + "\n"
    tree = etree.ElementTree(etree.fromstring(xml))
    depth(tree.getroot(), -1)
