如何使用JavaScript或jQuery将HTML表单数据保存为xml格式？

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

<input type="text" id="name" name="name" />
<input type="email" id="email" name="email" />
<textarea id="message" name="message"></textarea>

function saveFormDataAsXML() {
  var formData = {};

  // 获取表单数据
  formData.name = $('#name').val();
  formData.email = $('#email').val();
  formData.message = $('#message').val();

  // 创建XML文档
  var xml = '<?xml version="1.0" encoding="UTF-8"?>\n';
  xml += '<form>\n';
  xml += '  <name>' + formData.name + '</name>\n';
  xml += '  <email>' + formData.email + '</email>\n';
  xml += '  <message>' + formData.message + '</message>\n';
  xml += '</form>';

  // 下载XML文件
  var link = document.createElement('a');
  link.href = 'data:text/xml;charset=utf-8,' + encodeURIComponent(xml);
  link.download = 'form_data.xml';
  link.click();
}

<button onclick="saveFormDataAsXML()">保存为XML</button>
