js获取xml文档中的值

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

// 获取元素值
let value = xmlDoc.getElementsByTagName("element")[0].childNodes[0].nodeValue;
console.log(value); // 输出 "Value"

fetch('data.xml')
  .then(response => response.text())
  .then(str => (new window.DOMParser()).parseFromString(str, "application/xml"))
  .then(xmlDoc => {
    let value = xmlDoc.getElementsByTagName("element")[0].childNodes[0].nodeValue;
    console.log(value);
  })
  .catch(error => console.error('Error fetching XML:', error));

let xhr = new XMLHttpRequest();
xhr.open("GET", "data.xml", false); // 同步请求
xhr.send();
let xmlDoc = xhr.responseXML;

let value = xmlDoc.getElementsByTagName("element")[0].childNodes[0].nodeValue;
console.log(value);
