在JavaScript中对XML变量进行XML解析

const xmlString = "<root><name>John</name><age>30</age></root>";
const parser = new DOMParser();
const xmlDoc = parser.parseFromString(xmlString, "application/xml");
const name = xmlDoc.getElementsByTagName("name")[0].textContent;
const age = xmlDoc.getElementsByTagName("age")[0].textContent;
console.log("Name: " + name + ", Age: " + age);
