序言中不能有内容 [英] Content is not allowed in prolog

问题描述

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。

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.

因此我确保在xml声明之前没有字符。我甚至使用解决方案
http：// forums来处理BOM。 sun.com/thread.jspa?messageID=10324562#10324562

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

仍然没有运气，只发生一个xml。我甚至在编辑器中打开了xml并将其保存在一个带有 utf-8 编码的文件中。这真让我抓狂。任何的想法？

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?

更新：当您为 xsl 文件指定错误路径并找不到文件时，会出现此错误异常发生。
（这是我的情况。它可能对某人有所帮助。感谢您的回复）

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)

推荐答案

这种事情可以如果您的UTF-8文件带有 BOM ，并且您使用的是XML解析器，则会发生不知道。将XML文件保存为UTF-8，不含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.
