XML - 数据在根级别无效 [英] XML - Data At Root Level is Invalid

问题描述

我有一个XSD文件，它是连接codeD的UTF-8，以及任何文本编辑器，我通过运行它不会显示任何字符的文件的开头，但是当我把它在Visual Studio中的调试器，我清楚地看到在文件前面一个空框。

I have an XSD file that is encoded in UTF-8, and any text editor I run it through doesn't show any character at the beginning of the file, but when I pull it up in Visual Studio's debugger, I clearly see an empty box in front of the file.

我也得到了错误：

数据在根级别无效。行1，位置1。

任何人都知道这是什么？

Anyone know what this is?

更新：编辑职位的资格文件的类型。它是由微软的XSD创建者创建的XSD文件。

Update: Edited post to qualify type of file. It's an XSD file created by Microsoft's XSD creator.

推荐答案

事实证明，答案是我所看到的是一个的字节顺序标记，这是一个字符，告诉无论是加载文档是什么EN $ C $光盘，在我的情况，这是恩codeD的UTF-8，所以相应的BOM是 EF BB BF ，如下图所示。要删除它，我打开了它在记事本+ + 和UTF-点击恩code 8无BOM，如下图所示：

It turns out, the answer is that what I'm seeing is a Byte Order Mark, which is a character that tells whatever is loading the document what it is encoded in. In my case, it's encoded in utf-8, so the corresponding BOM was EF BB BF, as shown below. To remove it, I opened it up in Notepad++ and clicked on "Encode in UTF-8 without BOM", as shown below:

.

要真正看到的BOM，我不得不在 TextPad 在二进制模式，打开它并进行了<一href="http://www.google.com/search?hl=en&q=EF+BB+BF&btnG=Google+Search&aq=f&oq=">Google搜索 EF BB BF 。

To actually see the BOM, I had to open it up in TextPad in Binary mode:, and conducted a Google search for "EF BB BF".

我花了大约8个小时，找出这是什么导致它，所以我想我会和大家一起分享。

It took me about 8 hours to find out this was what was causing it, so I thought I'd share this with everyone.

更新：如果我读了乔尔斯波斯基的博客文章：的绝对最低每一个软件开发人员绝对，正面必须了解统一code和字符集（没有借口！）的的话，我可能不会有这个问题。

Update: If I had read Joel Spolsky's blog post: The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!), then I might not have had this problem.
