Nodejs/handlebars在创建超过特定大小的XML文件时遇到问题

我在生成XML文件时遇到问题。如果我只运行20个左右的“属性”：properties:properties.slice0，20我会得到一个有效的XML文件。如果我尝试运行我所有的properties:properties:properties，其中我有大约100个，那么我的XML是无效的

由于随机XML元素未正确关闭，它返回为无效

有什么线索可以解释为什么它对…20而不是100有效吗

生成XML的代码：

var express = require('express');
var router = express.Router();


router.get('/mits.xml', function(req, res) {
   var date = new Date();
   var y = date.getYear() + 1900;
   var m = date.getMonth() + 1;
   var d = date.getDate();

   api.getProperties(function(e, properties) {

      res.header('Content-Type', 'application/xml');
      res.render('mits/index', {
         properties: properties.slice(0,20),
         //properties: properties,
         layout: false,
         month: m,
         year: y,
         date: d
      });

   });
});

module.exports = router;

把手的模板文件：

代码似乎没有问题。我正在将xml从浏览器复制到验证工具中。如果我通过wget下载xml，它会很好地验证
