我正在做一个项目，我用 C# 创建一个 power point 文档。 一切都很好，但出于某种原因，我的一种方法出现了这个错误:
“状态 EndRootElement 中的 token StartElement 将导致无效的 XML 文档。”
这是我的方法:

对于大量的方法感到抱歉，但在这个方法中它会抛出错误。 任何帮助将不胜感激谢谢。
最佳答案
我的猜测是您已经关闭了最外层的元素，因此您不能打开一个新元素，因为 XML 只允许最外层有一个元素。
这种接口(interface)对于编写 XML 非常方便，我自己也使用它，但是如果你犯了任何嵌套错误，调试起来可能会很麻烦。众所周知，我将自己的包装器用于接口(interface)，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，这极大地有助于识别错误所在。
关于c# - 处于 EndRootElement 状态的 token StartElement 将导致无效的 XML 文档，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10752363/
我需要在客户计算机上运行Ruby应用程序。通常需要几天才能完成(复制大备份文件)。问题是如果启用sleep，它会中断应用程序。否则，计算机将持续运行数周，直到我下次访问为止。有什么方法可以防止执行期间休眠并让Windows在执行后休眠吗？欢迎任何疯狂的想法;-) 最佳答案 Here建议使用SetThreadExecutionStateWinAPI函数，使应用程序能够通知系统它正在使用中，从而防止系统在应用程序运行时进入休眠状态或关闭显示。像这样的东西:require'Win32API'ES_AWAYMODE_REQUIRED=0x0
我有一个对象has_many应呈现为xml的子对象。这不是问题。我的问题是我创建了一个Hash包含此数据，就像解析器需要它一样。但是rails自动将整个文件包含在.........我需要摆脱type="array"和我该如何处理？我没有在文档中找到任何内容。 最佳答案 我遇到了同样的问题；这是我的XML:我在用这个:entries.to_xml将散列数据转换为XML，但这会将条目的数据包装到中所以我修改了:entries.to_xml(root:"Contacts")但这仍然将转换后的XML包装在“联系人”中，将我的XML代码修改为
当我的预订模型通过rake任务在状态机上转换时，我试图找出如何跳过对ActiveRecord对象的特定实例的验证。我想在reservation.close时跳过所有验证!叫做。希望调用reservation.close!(:validate=>false)之类的东西。仅供引用，我们正在使用https://github.com/pluginaweek/state_machine用于状态机。这是我的预订模型的示例。classReservation["requested","negotiating","approved"])}state_machine:initial=>'requested
我有两个Rails模型，即Invoice和Invoice_details。一个Invoice_details属于Invoice，一个Invoice有多个Invoice_details。我无法使用accepts_nested_attributes_forinInvoice通过Invoice模型保存Invoice_details。我收到以下错误:(0.2ms)BEGIN(0.2ms)ROLLBACKCompleted422UnprocessableEntityin25ms(ActiveRecord:4.0ms)ActiveRecord::RecordInvalid(Validationfa
如何在ruby中调用C#dll？ 最佳答案 我能想到几种可能性:为您的DLL编写(或找人编写)一个COM包装器，如果它还没有，则使用Ruby的WIN32OLE库来调用它；看看RubyCLR,其中一位作者是JohnLam，他继续在Microsoft从事IronRuby方面的工作。(估计不会再维护了，可能不支持.Net2.0以上的版本)；正如其他地方已经提到的，看看使用IronRuby，如果这是您的技术选择。有一个主题是here.请注意，最后一篇文章实际上来自JohnLam(看起来像是2009年3月)，他似乎很自在地断言RubyCL
我正在尝试在Ruby中复制Convert.ToBase64String()行为。这是我的C#代码:varsha1=newSHA1CryptoServiceProvider();varpasswordBytes=Encoding.UTF8.GetBytes("password");varpasswordHash=sha1.ComputeHash(passwordBytes);returnConvert.ToBase64String(passwordHash);//returns"W6ph5Mm5Pz8GgiULbPgzG37mj9g="当我在Ruby中尝试同样的事情时，我得到了相同sha
对于作为String#tr参数的单引号字符串文字中反斜杠的转义状态，我觉得有些神秘。你能解释一下下面三个例子之间的对比吗？我特别不明白第二个。为了避免复杂化，我在这里使用了'd'，在双引号中转义时不会改变含义("\d"="d")。'\\'.tr('\\','x')#=>"x"'\\'.tr('\\d','x')#=>"\\"'\\'.tr('\\\d','x')#=>"x" 最佳答案 在tr中转义tr的第一个参数非常类似于正则表达式中的括号字符分组。您可以在表达式的开头使用^来否定匹配(替换任何不匹配的内容)并使用例如a-f来匹配一
我目前正在使用以下方法获取页面的源代码:Net::HTTP.get(URI.parse(page.url))我还想获取HTTP状态，而无需发出第二个请求。有没有办法用另一种方法做到这一点？我一直在查看文档，但似乎找不到我要找的东西。 最佳答案 在我看来，除非您需要一些真正的低级访问或控制，否则最好使用Ruby的内置Open::URI模块:require'open-uri'io=open('http://www.example.org/')#=>#body=io.read[0,50]#=>"["200","OK"]io.base_ur
