How to Parse XML in Node.js with Example Code

Introduction

XML (Extensible Markup Language) is a markup language that is used to store and transport data. It is a popular data format used for data interchange on the web. Node.js is a JavaScript runtime environment that allows developers to create server-side applications. In this article, we will learn how to parse XML in Node.js with example code.

Using the xml2js Library

The xml2js library is a popular library for parsing XML in Node.js. It is a simple and lightweight library that can be used to parse XML data. It is easy to use and provides a number of features such as support for namespaces, custom parsers, and more.

Example Code

The following example code shows how to parse an XML document using the xml2js library. The code reads an XML document from a file and parses it into a JavaScript object.

const fs = require('fs');
const xml2js = require('xml2js');

fs.readFile('example.xml', (err, data) => {
  if (err) throw err;
  const parser = new xml2js.Parser();
  parser.parseString(data, (err, result) => {
    if (err) throw err;
    console.log(result);
  });});
