JavaScript读取XML文件的几种方法

const xhr = new XMLHttpRequest();
xhr.open('GET', 'path/to/your/file.xml', true);
xhr.onreadystatechange = function () {
  if (xhr.readyState === 4 && xhr.status === 200) {
    const xmlDoc = xhr.responseXML;
    console.log(xmlDoc);  // 这里你可以操作XML DOM
  }
};
xhr.send();

fetch('path/to/your/file.xml')
  .then(response => response.text())
  .then(data => {
    const parser = new DOMParser();
    const xmlDoc = parser.parseFromString(data, 'application/xml');
    console.log(xmlDoc);  // 操作xmlDoc
  })
  .catch(error => console.error('Error loading the XML file:', error));

npm install xml2js

const fs = require('fs');
const xml2js = require('xml2js');
 
// 读取XML文件
fs.readFile('path/to/your/file.xml', 'utf8', (err, data) => {
  if (err) {
    console.error('Error reading XML file:', err);
    return;
  }
 
  // 解析XML字符串为JavaScript对象
  const parser = new xml2js.Parser();
  parser.parseString(data, (err, result) => {
    if (err) {
      console.error('Error parsing XML:', err);
      return;
    }
 
    console.log(result);  // 解析后的JavaScript对象
  });
});

const title = xmlDoc.getElementsByTagName('title')[0].textContent;
console.log(title);

console.log(result.root.title[0]);  // 假设XML结构类似 <root><title>...</title></root>
