如何使用Node.js检查字符串是否为xml

const fs = require('fs');
const { DOMParser } = require('xmldom');

function isXMLString(str) {
  try {
    const parser = new DOMParser();
    parser.parseFromString(str, 'text/xml');
    return true;
  } catch (error) {
    return false;
  }
}

const xmlString = '<root><element>Value</element></root>';
console.log(isXMLString(xmlString)); // 输出 true

const nonXMLString = 'This is not XML';
console.log(isXMLString(nonXMLString)); // 输出 false
