    <course>Computer Science</course>
    <grade>A</grade>
</student>

Browser Display:

- name: Alex Smith

- age: 20

- course: Computer Science

- grade: A

🔹 Viewing XML in Browsers

Web browsers can display XML files with syntax highlighting and collapsible tree structure, making it easy to read and navigate complex XML documents.

🔸 Simple XML File:

<?xml version="1.0" encoding="UTF-8"?>
<bookstore>
    <book category="fiction">
        <title>The Great Novel</title>
        <author>Jane Doe</author>
        <price>12.99</price>
    </book>
</bookstore>

Browser Features:

Color Coding: Different colors for tags, attributes, and values
Collapsible Nodes: Click to expand/collapse sections
Line Numbers: Easy reference to specific lines
Error Detection: Shows syntax errors clearly

🔹 Using XML with Programming Languages

XML files can be read and processed by virtually all programming languages. This makes XML perfect for data exchange between different applications and systems.

🔸 JavaScript Example:

// Load and parse XML
const parser = new DOMParser();
const xmlString = '<person><name>John</name></person>';
const xmlDoc = parser.parseFromString(xmlString, "text/xml");

// Get data
const name = xmlDoc.getElementsByTagName("name")[0].textContent;
console.log(name); // Output: John

🔸 Python Example:

import xml.etree.ElementTree as ET

# Parse XML
tree = ET.parse('data.xml')
root = tree.getroot()

# Access data
for child in root:
    print(child.tag, child.text)
