Java: MalformedByteSequenceException (XML)
提问by Nick Heiner
I'm trying to parse XML using this class. When I type out a simple file, it works fine.
我使用这个试图解析XML类。当我输入一个简单的文件时，它工作正常。
<testData>
<text>
odp
</text>
</testData>
Here is my main
这是我的 main
public static void main(String[] args) {
Xml train = new Xml(args[0], "trainingData");
Xml test = new Xml(args[1], "testData");
}
However, when I use the file I got by copying and pasting from MSFT Office OneNote, I get errors:
但是，当我使用通过从 MSFT Office OneNote 复制和粘贴获得的文件时，出现错误：

What is causing this? I edited the problematic XML file in Notepad++ and changed the encoding to UTF-8. This caused a bunch of weird characters from the accents/special quotation marks, which I edited out. Am I not converting properly?
这是什么原因造成的？我在 Notepad++ 中编辑了有问题的 XML 文件并将编码更改为UTF-8. 这导致重音/特殊引号中出现了一堆奇怪的字符，我已将其删除。我没有正确转换吗？
(I don't know anything about text encoding formats, in case you couldn't tell.)
（我对文本编码格式一无所知，以防万一你不知道。）

Your file is not properly encoded as UTF-8 but your parser is expecting UTF-8 encoding.
您的文件未正确编码为 UTF-8，但您的解析器需要 UTF-8 编码。
It would help to pin-point the problem is you can post a hexdump of the file.
这将有助于查明问题是您可以发布文件的十六进制转储。
