我有一个XML树，我正在解析和设置列向下钻取HighChart选项。但是，HTML呈现一个空白页：列向下钻取图表 - 通过XML数据源解析展开

我不知道什么的问题是，为什么图表没有被呈现？
============================================== ====================================
修改/更新的代码：
我在我的代码中做了一些修改，但仍然无法在浏览器中使用上述线程中提到的相同XML树结构查看Column DrillDown图。 我只获得“浏览市场份额，2011年4月”的标题，其他内容均为空白。 请注意第127行和第128行的代码 - 我无法找到设置图表初始系列名称和级别方法的方法。请帮我完成我的项目？我完全陷入了这个问题：

最后如何将此图表选项设置为图表？
将选项设置为图表的问题是我找不到正确设置图表选项的正确方法。由于我的函数是递归的，我不知道如何创建和正确设置从XML树处理的图表选项？
在此先感谢 - 请让我知道我该如何解决问题，因为我完全陷入困境。
我已经更新了我的问题与我的修改后的代码：
如果你希望你可以看看这个获取更多信息。我成功地能够解析XML树，但无法正确地将其设置为图表选项。 – Prakash 2012-03-19 08:43:23
@Prakash你正确地得到的价值？你是否尝试了一个警报，看看你是否获得系列，类别或任何？ – sameer 2012-03-19 09:27:42
@Prakash http://jsfiddle.net/wcQBa/只是看到这个，节点值不包含在单引号之间 – sameer 2012-03-19 10:12:50
