How to convert an XML string to a dictionary?

📝 Hey there, tech enthusiasts! Today, we're diving into the realm of XML and dictionaries. 📚 We'll explore the question of how to convert an XML string to a dictionary in a Python program. So, let's get started! 🚀

🔍 The Problem: Imagine you have a program that receives an XML document from a socket. 📡 You have stored the XML document as a string and now want to convert it into a Python dictionary. 🤔 This seamless conversion is similar to what Django's simplejson library offers.

🎯 The Desired Outcome: Given an XML string, the goal is to convert it into a dictionary. For example, if we have the following XML string:

str = "<?xml version="1.0" ?><person><name>john</name><age>20</age></person>"

We aim to transform this XML string, str, into the corresponding dictionary:

dic_xml = {'person': {'name': 'john', 'age': 20}}

Now that we know what we want to achieve, let's explore some solutions! 💡

🔧 Solution 1 - Using the xmltodict Library: One way to convert an XML string to a dictionary is by using the xmltodict library in Python. This library simplifies the process by providing a convenient parse() function. Here's how you can use it:

import xmltodict

str = "<?xml version="1.0" ?><person><name>john</name><age>20</age></person>"

# Convert XML string to dictionary
dic_xml = xmltodict.parse(str)

print(dic_xml)

🔧 Solution 2 - Using ElementTree: Another approach is to use Python's built-in ElementTree module. This module provides easy-to-use functionality for parsing XML documents. Here's an example:

import xml.etree.ElementTree as ET

str = "<?xml version="1.0" ?><person><name>john</name><age>20</age></person>"

# Create ElementTree object from XML string
tree = ET.ElementTree(ET.fromstring(str))

# Get the root element
root = tree.getroot()

# Convert XML element to dictionary
dic_xml = {}
for child in root:
    dic_xml[child.tag] = child.text

print(dic_xml)
