How to Open and Read XML Files

import xml.etree.ElementTree as ET

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

# Access elements
for device in root.findall('device'):
    hostname = device.find('hostname').text
    ip = device.find('ipAddress').text
    print(f"Device: {hostname}, IP: {ip}")

# Access attributes
device_type = root.find('device').get('type')

const fs = require('fs');
const { DOMParser } = require('xmldom');

// Read XML file
const xmlString = fs.readFileSync('config.xml', 'utf8');
const parser = new DOMParser();
const xmlDoc = parser.parseFromString(xmlString, 'text/xml');

// Access elements
const devices = xmlDoc.getElementsByTagName('device');
for (let i = 0; i < devices.length; i++) {
  const hostname = devices[i]
    .getElementsByTagName('hostname')[0]
    .textContent;
  console.log('Hostname:', hostname);
}

import javax.xml.parsers.*;
import org.w3c.dom.*;
import java.io.File;

// Parse XML file
DocumentBuilderFactory factory = 
    DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(new File("config.xml"));

// Normalize XML structure
doc.getDocumentElement().normalize();

// Access elements
NodeList devices = doc.getElementsByTagName("device");
for (int i = 0; i < devices.getLength(); i++) {
    Element device = (Element) devices.item(i);
    String hostname = device
        .getElementsByTagName("hostname")
        .item(0)
        .getTextContent();
    System.out.println("Hostname: " + hostname);
}

using System.Xml;

// Load XML file
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("config.xml");

// Access elements
XmlNodeList devices = xmlDoc.GetElementsByTagName("device");
foreach (XmlNode device in devices)
{
    string hostname = device["hostname"].InnerText;
    string ip = device["ipAddress"].InnerText;
    Console.WriteLine($"Device: {hostname}, IP: {ip}");
}

// Access attributes
string deviceType = devices[0].Attributes["type"].Value;
