Question

我正在尝试在我的一台服务器中使用XSLT组合一组XML文件，并为文件集（不是所有文件）收到以下错误：

我尝试了xslt的document()和collection()方法，可以用来组合文件。但得到同样的错误。

主要问题是，此错误仅在此特定服务器上发生。当我在本地或其他服务器上运行相同的文件集时，它运行没有任何问题。

此过程中使用以下内容：

XSLT 2.0

saxon 9.7.0-8

java 1.7.0_95

非常感谢任何帮助。

它在Oracle XDK解析器中深深地崩溃了（Saxon只是传递了坏消息）。不幸的是，解析器不是开源的，我怀疑Oracle正在监控这个论坛，所以从技术上讲，你应该向Oracle提出支持请求。在实践中，您最好的方法可能是切换到不同的解析器：内置于JDK的解析器或Apache Xerces。

我怀疑你使用XDK解析器的唯一原因是它碰巧出现在类路径上，或出现在＆＃34;认可的库中＃34; 。目录

使用方法Processor.setConfigurationProperty(FeatureKeys.SOURCE_PARSER_CLASS, className)调用document（）函数时，可以更改Saxon使用的解析器。
