问题描述
我正在做一个项目，在该项目中我从 C# 创建了一个 Power Point 文档.由于某种原因，在我的一种方法上一切都很好，但我收到此错误:
I am working on a project where as i create a power point document from c#.Its all ging very well bu for some reason on one of my methods i am getting this error:
处于 EndRootElement 状态的令牌 StartElement 将导致无效的 XML 文档."
"Token StartElement in state EndRootElement would result in an invalid XML document."
这是我的方法:

很抱歉使用了大量方法，但在此方法中它会引发错误.任何帮助将不胜感激谢谢.
Sorry for the massive method but in this method it throws the error.Any help will be appreciated Thanks.
推荐答案
我的猜测是你已经关闭了最外层的元素，所以你不能打开一个新的，因为 XML 只允许最外层的一个元素.
My guess would be that you have closed the outermost element, so you are not allowed to open a new one because XML only allows one element at the outermost level.
这种接口写XML非常方便，我自己也用过，但是如果嵌套错误的话，调试起来会很麻烦.众所周知，我对接口使用自己的包装器，其中对 endElement 的调用必须指定匹配的标记名称；然后包装器可以检查调用的正确嵌套，这有助于确定错误在哪里.
This kind of interface is very handy for writing XML and I use it myself, but it can be a pig to debug if you make any nesting mistakes. I've been known to use my own wrapper for the interface in which the calls to endElement have to specify the matching tag name; the wrapper can then check the correct nesting of the calls, which helps greatly to identify where the error is.
