JavaScript对HTML文件进行数据访问

要求

用JavaScript对HTML文件（见上一篇博客）进行数据访问，将获得的所有个人简历信息项的值以XML方式进行组织，并通过对话框显示出来；
（具体来说就是通过DOM来获得所有个人简历信息项的值，并显示在网页显示）

源代码

//进入页面的提示信息
alert("建议使用chrome或360浏览器打开");         
          //正则表达式校验手机号
		  function checkphone(){
        	  var phone=document.getElementById('textphone').value;
        	  var regx=/^1[3|5|7|8]{1}[0-9]{9}$/;
        	  var flag=regx.test(phone);
        	return flag;
          }
		  //正则表达式校验邮箱格式
		  function checkmail(){
			  var reg = /^[a-zA-Z0-9]+([-_.][a-zA-Z0-9]+)*@[a-zA-Z0-9]+([-_.][a-zA-Z0-9]+)*\.[a-z]{2,}$/;
              var mail=document.getElementById('textmail').value;
              var flag=reg.test(mail);
			  return flag;
		  }
		  //获取文本框中的值
         function gettext(id){
        	 return document.getElementById(id).value;
         }
		//获取下拉列表框的值
		function getselect(id)
		{
		return document.getElementById(id).value;
		}

		function check(){//将数据显示成xml格式

			if(checkphone()&&checkmail()){
			 alert(content);
		     }
		 else{
		     if(!checkphone()){
				 alert('手机号不符合正则表达式规范');
			 }
			 if(!checkmail()){
				 alert('邮箱格式不符合正则表达式规范');
			 }
		 }   
		} 

HTML加入的代码

//位置自己定，我放在了class3块下
//添加按钮
  <input type="button" style="background-color:white;height:30px;" value="xml格式数据" onclick="check()">
  //引用js
		<script src="个人简历.js">
        </script>
