这是一个延续of another question。当我尝试解析我的xml文件时，我收到此错误。
Exception in thread "main" org.xml.sax.SAXParseException; lineNumber: 68; columnNumber: 12; Content is not allowed in trailing section.

“lineNumber：68; columnNumber：12;”部分与最后一个'＆gt;'匹配在我的xml文件中。当我尝试删除它后面的空白区域时，它仍然给我错误。我试图把它扔进xml validator，但它没有提出任何东西。我真的不确定我在做什么。我尝试了其他堆栈溢出问题的其他解决方案（查看我的文件，找到xml文件后的任何奇怪的字符，确保所有标签都关闭）但是没有一个能为我工作。
有人有任何提示我现在应该去哪里吗？哪个是最好的方向？

答案 0 :(得分：3)
您可能会遇到解析错误，因为您的文件编码与XML声明中的编码不匹配：
<?xml version="1.0" encoding="utf-16"?>
FileWriter和FileReader假设默认字符编码是可接受的（我系统上的UTF-8）。您不能依赖它们以便携方式处理UTF-16编码文件。这是他们的文档：
用于编写字符文件的便捷类。此类的构造函数假定默认字符编码和默认字节缓冲区大小是可接受的。要自己指定这些值，请在FileOutputStream上构造OutputStreamWriter。
读取字符文件的便捷类。此类的构造函数假定默认字符编码和默认字节缓冲区大小是适当的。要自己指定这些值，请在FileInputStream上构造一个InputStreamReader。
所以你需要做文档建议的 - 使用替代方案。
以下是一些快速测试代码，可通过您的removeLineFromFile方法的三种不同实现来演示您的问题：

removeLineFromFile2表示您需要做的事情，removeLineFromFile1表示如果您正确阅读内容会发生什么，但是以错误的方式写出来（我怀疑您的情况正在发生） removeLineFromFile是您的实现，在我的系统上什么都不做。
getAndParseFile
Temp file is: \path\to\sample-utf16.xml.2.tmp
Temp file is: \path\to\sample-utf16.xml.1.tmp
Finished Removing Lines

Done with \path\to\sample-utf16.xml.1.tmp

以上所有假设您的输入文件确实是XML文件中指定的UTF-16。我认为情况并非如此。如果你自己创建了文件，那么你是以错误的方式完成的。尝试在Notepad ++（或类似工具）中打开它，并通过编码菜单检查编码（应该说是UCS-2或UTF-16，而不是ANSI，UTF-8等）。
您的代码应始终明确指定所需文件的编码。
