XML解析错误补救

Question

解析XML文件的过程中，我面临的解析错误，如[Fatal Error] :293:24: Invalid byte 2 of 2-byte UTF-8 sequence.我的XML样品中含有像XC3，这是一个字符（我的意思是通过按下Delete键一次XC3字符删除一些字符的时间。（我想这个角色粘贴在这里，但这个编辑器显示其它字符）。

解析

我的Java代码是在这里下面。

 DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance(); 
     docBuilderFactory.setValidating(false); 
     docBuilderFactory.setCoalescing(false); 
     docBuilderFactory.setXIncludeAware(false); 
     docBuilderFactory.setNamespaceAware(false); 
     docBuilderFactory.setIgnoringComments(true); 
     docBuilderFactory.setExpandEntityReferences(false); 

     DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder(); 
     Document doc = docBuilder.parse(rtfXmlIS); 
     doc.getDocumentElement().normalize(); 

如何摆脱这样的错误（[Fatal Error] :16:45: Invalid byte 1 of 1-byte UTF-8 sequence.,[Fatal Error] :14:24: The entity "ndash" was referenced, but not declared.）？

Answer 1

这是两个不同的错误。

第一个是因为输入不是UTF-8。在将它传递给解析器之前，您需要正确解码输入。

第二个可能是因为输入是XHTML而不是XML。如果你想使用这个输入的XML解析器并解析像–这样的实体，你将需要提供一个DTD来定义它和输入中包含的任何其他实体。
