To read an XML file in React.js, you can make use of the fetch() function provided by the browser's window object. Here's an example of how you can accomplish this:

  1. Install the xml2js library using npm:
1
npm install xml2js


  1. Import the necessary libraries:
1
2
import { useEffect, useState } from 'react';
import xml2js from 'xml2js';


  1. Create a function to fetch and parse the XML file:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
const readXmlFile = async () => {
  const response = await fetch('path/to/xml/file.xml');
  const xmlText = await response.text();

  // Convert XML to JSON
  const parser = new xml2js.Parser();
  const parsedXml = await parser.parseStringPromise(xmlText);

  // Access the XML data as JSON
  console.log(parsedXml);
};


  1. Call the function within a React component:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
const ExampleComponent = () => {
  useEffect(() => {
    readXmlFile();
  }, []);

  return (
    <div>
      {/* Your JSX code */}
    </div>
  );
};


Here, we use the useEffect() hook to call the readXmlFile() function when the component is mounted. Adjust the fetch() function to specify the correct path to your XML file.


The parsedXml variable will contain the XML data parsed into a JSON format, which you can then access and display in your React component as needed.
