Я бы попробовал xml2js , это делает преобразование XML в JSON очень простым:
const xml2js = require('xml2js');
function testXmlParse(xml) {
const parser = new xml2js.Parser( { explicitArray: false })
parser.parseString(xml, (err, result) => {
if (err) {
console.error("An error occurred: ", err);
} else {
console.log("Xml to Json result: ", result);
}
})
}
const xmlInput = "<note><to>Tove</to><from>Jani</from><heading>Reminder</heading><body>Don't forget me this weekend!</body></note>";
testXmlParse(xmlInput);
Вот пример некоторых манипуляций с XML с использованием xmldom :
const xmldom = require('xmldom');
const xpath = require('xpath');
var parser = new xmldom.DOMParser();
var serializer = new xmldom.XMLSerializer();
