Node.js NodeList to XML字符串

function nodeListToXmlString(nodeList) {
  let xmlString = '';

  for (let i = 0; i < nodeList.length; i++) {
    const node = nodeList[i];

    if (node.nodeType === 1) { // 1 表示元素节点
      xmlString += `<${node.tagName}`;

      // 处理节点属性
      const attributes = node.attributes;
      for (let j = 0; j < attributes.length; j++) {
        const attribute = attributes[j];
        xmlString += ` ${attribute.name}="${attribute.value}"`;
      }

      xmlString += '>';

      // 处理子节点
      if (node.hasChildNodes()) {
        xmlString += nodeListToXmlString(node.childNodes);
      }

      xmlString += `</${node.tagName}>`;
    } else if (node.nodeType === 3) { // 3 表示文本节点
      xmlString += node.textContent;
    }
  }

  return xmlString;
}

// 示例用法
const jsdom = require('jsdom');
const { JSDOM } = jsdom;

const htmlString = '<div><p>Hello</p><p>World</p></div>';
const dom = new JSDOM(htmlString);
const nodeList = dom.window.document.querySelectorAll('div');

const xmlString = nodeListToXmlString(nodeList);
console.log(xmlString);
