为什么XMLEventReader不读取XML Version = 1.1

Question

我编写了一个程序，它读取一堆XML文件，然后对它们进行比较。此程序的工作方式类似于XML Version 1.0的宝石，但它会突破XML version 1.1以下的异常。有人可以帮忙吗？

Exception in thread "main" java.lang.NullPointerException
    at com.sun.org.apache.xerces.internal.impl.XML11NSDocumentScannerImpl.scanStartElement(XML11NSDocumentScannerImpl.java:351)
    at com.sun.org.apache.xerces.internal.impl.XML11NSDocumentScannerImpl$NS11ContentDriver.scanRootElementHook(XML11NSDocumentScannerImpl.java:889)
    at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDriver.next(XMLDocumentFragmentScannerImpl.java:3104)

    at com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.next(XMLStreamReaderImpl.java:554)

我知道有类似的问题here。我已经下载了xercesImpl.jar:xml-apis.jar并尝试了但我仍然得到了同样的例外。我已经下载了下图中突出显示的拉链。

编辑1：发布XML文件。（已编辑XML以隐藏客户特定的详细信息）
