状态为 EndRootElement 的令牌 StartElement 将导致无效的 XML 文档
本文关键字：无效 XML 文档 StartElement EndRootElement 令牌 状态 | 更新日期: 2023-09-27 18:35:23
我正在做一个项目，当我从 c# 创建一个 Power Point 文档时。一切都很顺利，但由于某种原因，在我的一种方法上，我收到此错误：
"状态为 EndRootElement 的令牌 StartElement 将导致无效的 XML 文档。
这是我的方法：

很抱歉使用大量方法，但在此方法中它会抛出错误。
我的猜测是你已经关闭了最外层的元素，所以不允许你打开一个新元素，因为XML只允许最外层的一个元素。
这种接口对于编写XML非常方便，我自己也使用它，但是如果您犯了任何嵌套错误，则调试起来可能会很麻烦。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签名称;然后，包装器可以检查调用的正确嵌套，这有助于识别错误的位置。
你调用 startelement 81 次......你猜怎么着：你没有调用 endelement 81 次......
因此，请确保开始和结束正确匹配;)
