js怎么解析xml

let xmlString = "<root><element>value</element></root>";
let parser = new DOMParser();
let xmlDoc = parser.parseFromString(xmlString, "application/xml");

// 访问XML节点
let element = xmlDoc.getElementsByTagName("element")[0];
console.log(element.textContent); // 输出: value

let xhr = new XMLHttpRequest();
xhr.open("GET", "example.xml", true);
xhr.onreadystatechange = function() {
    if (xhr.readyState === 4 && xhr.status === 200) {
        let parser = new DOMParser();
        let xmlDoc = parser.parseFromString(xhr.responseText, "application/xml");
        // 处理解析后的XML
    }
};
xhr.send();

const sax = require('sax');
const strict = true; // 严格模式
const parser = sax.parser(strict);

parser.onopentag = function (node) {
    console.log('Open tag:', node.name);
};
parser.ontext = function (text) {
    console.log('Text:', text);
};
parser.onclosetag = function (nodeName) {
    console.log('Close tag:', nodeName);
};

let xmlString = "<root><element>value</element></root>";
parser.write(xmlString).close();
