How does xml2js.parseString work?

xml2js.parseString is a method in the xml2js library that converts XML data to a JavaScript object using a callback function, allowing for easy traversal of the XML tree structure. It first takes the XML string, then parses it into a JavaScript object with its properties and values determined by the XML data. The callback function then uses the resulting object to manipulate and work with the data.

const xml2js = require("xml2js");

const xmlString = " John 30 ";

xml2js.parseString(xmlString, (err, result) => {
  if (err) {
    console.error(err);
  } else {
    console.log(result);
  }
});

In this example, the xmlString variable contains a simple XML string that represents a person's name and age. The xml2js.parseString() function is then called with the xmlString variable as its first argument, and a callback function as its second argument. When xml2js.parseString() is executed, it takes the XML string and parses it into a JavaScript object. If an error occurs during parsing, the err parameter in the callback function will contain information about the error. Otherwise, the result parameter in the callback function will contain the parsed JavaScript object, which in this case will look like this: javascript Copy code
