为array.length AngularJS未定义的错误

Question

我将XML转换到HTML表格，但在内部进行循环我'得到undefined错误Row[i].cell.length inspite该小区有SPACER的

查找演示 here

所需输出表 -

注意：警惕你会得到是该行的length

Answer 1

的错误是RAIS当行节点有单个元素里面。

我已经修改了字符串元素转化成数组的代码，但纠正错误后，已经出来了别人，我想正确的，但我觉得他们应该进行审查。

的JSFiddle

在这里，新的代码

var myApp = angular.module('myApp', []); 

myApp.controller("MyCtrl", function($scope) {
