序言中不允许出现内容
我正在尝试使用 xslt 将 xml 转换为 html。我使用 java.xml.transform 在 java 中执行此操作。 它工作正常，直到我遇到一些 xml。它说以下错误。
[Fatal Error] :1:1: Content is not allowed in prolog.
javax.xml.transform.TransformerConfigurationException:
javax.xml.transform.TransformerConfigurationException:
javax.xml.transform.TransformerException:
org.xml.sax.SAXParseException: Content is not allowed in prolog.
所以我确保 xml 声明之前没有字符。我什至使用该解决方案处理了 BOM http://forums.sun.com/thread.jspa?messageID=10324562#10324562
仍然没有运气，它只发生在一个 xml 上。我什至在编辑器中打开 xml 并将其保存在使用 utf-8 编码的文件中。这让我发疯。有什么想法吗？
更新：当您为 xsl 文件提供了错误的路径并且发生文件未找到异常时，您会收到此错误。 （这是我的情况。它可能对某人有帮助。感谢您的回复）
i'm trying to convert xml to html using xslt. Am using java.xml.transform to do this in java.
it was working fine until i bumped into some xml. it said the following error.
[Fatal Error] :1:1: Content is not allowed in prolog.
javax.xml.transform.TransformerConfigurationException:
javax.xml.transform.TransformerConfigurationException:
javax.xml.transform.TransformerException:
org.xml.sax.SAXParseException: Content is not allowed in prolog.
so i made sure there is no character before the xml declaration. i even took care of BOM using the solution
http://forums.sun.com/thread.jspa?messageID=10324562#10324562
STILL no luck and it happens only for one xml. i even opened the xml in editor and saved it in a file with utf-8 encoding. this is driving me crazy. any idea?
UPDATE: You get this error when you have given the wrong path for the xsl file and a file not found exception happens.
(this was my case. it might help somebody. thanks for your responses)

如果您有一个带有 BOM 的 UTF-8 文件，并且如果您使用不知道这一点的 XML 解析器。将 XML 文件另存为 UTF-8 without BOM。
This kind of thing can happen if you have an UTF-8 file with a BOM, and if you use an XML parser that isn't aware of it. Save the XML file as UTF-8 without BOM.
你的文件中有标题吗？类似于：
这应该位于第一行的开头。不幸的是，我看不到您的 XML 文件，因为该 URL 在我所在的位置被屏蔽了。
Do you have a header in your file? Something like:
<?xml version="1.0" encoding="utf-8"?>That should be at the start of the first line. Unfortunately I can't see your XML file as that URL is blocked from where I am.
