reactjsHow can I use React.js to parse XML data?

React.js can be used to parse XML data using the xmldom library. The following example code uses xmldom to parse an XML string and print out the node name of each node in the XML string:

const xmldom = require('xmldom');

const xmlString = `
  <root>
    <node1>
      <child1 />
    </node1>
    <node2>
      <child2 />
    </node2>
  </root>
`;

const doc = new xmldom.DOMParser().parseFromString(xmlString);

const nodes = doc.getElementsByTagName('*');

for (let i = 0; i < nodes.length; i++) {
  console.log(nodes[i].nodeName);
}

Output example

root
node1
child1
node2
child2

In the example code, the xmldom library is imported (1), an XML string is defined (2), the XML string is parsed into a DOM object (3), all nodes in the DOM object are retrieved (4), and the node name of each node is printed out (5).

React.js can also be used to parse XML data using the xml2js library. The xml2js library can be used to parse XML data into JavaScript objects.
