Parsing XML to JavaScript Object

This feature allows you to parse XML data and convert it into a JavaScript object. The 'parseString' method takes an XML string and a callback function that receives the parsed result.

const xml2js = require('xml2js');
const parser = new xml2js.Parser();
const xml = '<root>Hello xml2js!</root>';

parser.parseString(xml, (err, result) => {
  console.log(result);
});

Converting JavaScript Object to XML

This feature enables you to take a JavaScript object and convert it into an XML string. The 'Builder' class is used to create an XML string from the provided object.

const xml2js = require('xml2js');
const builder = new xml2js.Builder();
const obj = { root: 'Hello xml2js!' };

const xml = builder.buildObject(obj);
console.log(xml);

Customizing Parser Options

xml2js allows you to customize the behavior of the parser through various options. In this example, 'explicitArray' is set to false to avoid wrapping single elements in an array, and 'trim' is set to true to trim the whitespace from the text nodes.

const xml2js = require('xml2js');
const parser = new xml2js.Parser({
  explicitArray: false,
  trim: true
});
const xml = '<root>    Hello xml2js!    </root>';

parser.parseString(xml, (err, result) => {
  console.log(result);
});
