所以今天我在这里问了几个问题，在惊人的so社区的帮助下，我已经能够理解SAX的基础知识，并学习如何正确地遍历目录结构

现在，通过我的程序，我可以访问我正在寻找的XML文件，但我不确定我得到的这个错误意味着什么，也不确定我在SAXHandler类的代码中出错的地方。有人能看看这个并给我一些反馈吗

提前感谢您的帮助

在每个开始元素上，检查它是否等于“Relationship”，但第一个元素是“Relationships”，因此它不等于，并抛出异常。这就是您迄今为止实施的行为；）

这就是我所指的代码的和平：

public void startElement(String uri, String localName, 
                 String qName, Attributes attrs) throws SAXException 
         {
             if(localName.equalsIgnoreCase("Relationship"))
             {
                 .....
             }  
             else 
             {
                 throw new IllegalArgumentException("Element '" + 
                         qName + "' is not allowed here");
             }
         }

一个可能的解决方案（这肯定不是好的风格，但解决了你面临的问题）

您的XML看起来像什么？顺便说一下，我猜您有两个顶级元素。您的代码可能没有问题。问题似乎出在源文档上。文档似乎不符合架构。只需删除dtd定义并尝试使用sax读取该文件，它应该可以工作（以验证我的假设）@Ted Hopp、@doc_180抱歉，我第一次忘了包含xml文档。它现在在原来的帖子中。@Joe-在开始之前是

。

@Joe然后删除它，因为它不属于那里，它会使它成为一个无效的XML文件。@Joerg M.嗯，是的，我知道从现在开始出现错误的地方了。但这是否意味着localName不是“关系”？如果是这样，我应该从什么开始访问“关系”？看，这个方法是一个回调处理程序。这个回调处理程序会在xml中的每个开始标记上启动。。。但本例中的根元素“relationships”也是一个开始标记。使用elseif处理localName等于“Relationships”的情况@Joerg M可以很容易地解决这个问题。我遵照您的建议，添加了一个新的else if语句来处理“Relationships”标记。然而，我仍然得到同样的错误。我在原始代码中加入了我所做的更改。@Joerg M.只是对我的代码做了一点修改。我按照你说的做了，包括else-if语句，但是，与使用LocalName相反，我使用了qName…令人惊讶的是，它起了作用。现在…我不知道为什么会这样，从我收到的解释来看，人们告诉我他们基本上是一样的。你明白吗？编辑：代码中反映的更改以我的示例为例，用qName替换localName。你不会得到一个错误。我纠正一下这个例子。
public void startElement(String uri, String localName, 
                 String qName, Attributes attrs) throws SAXException 
         {
             if(localName.equalsIgnoreCase("Relationship"))
             {
                 .....
             }  
             else 
             {
                 throw new IllegalArgumentException("Element '" + 
                         qName + "' is not allowed here");
             }
         }
