将大型XML文件读入Javascript时出现问题

// 使用SAX解析器
const parser = new SAXParser();
parser.on('startElement', function(node) {
  console.log(node);
});
parser.on('endElement', function(node) {
  console.log(node);
});
parser.parse(xmlString);

// 使用Web Worker进行异步处理
const worker = new Worker('parseWorker.js');
worker.postMessage(xmlString);
worker.onmessage = function(event) {
  console.log(event.data);
};

// 使用虚拟DOM库（如React）
import React from 'react';
import ReactDOM from 'react-dom';

const XMLComponent = () => {
  const [data, setData] = React.useState([]);

  React.useEffect(() => {
    const parser = new DOMParser();
    const xmlDoc = parser.parseFromString(xmlString, 'text/xml');
    const nodes = Array.from(xmlDoc.querySelectorAll('node'));
    setData(nodes);
  }, []);

  return (
    <div>
      {data.map((node, index) => (
        <div key={index}>{node.textContent}</div>
      ))}
    </div>
  );
};

ReactDOM.render(<XMLComponent />, document.getElementById('root'));
