Java XMLReader不清除多字节UTF-8编码的属性

问题描述

我有一个非常奇怪的情况，我的SAX ContentHandler由XMLReader处理错误的属性。要解析的文档是UTF-8，其中包含XML属性中的多字节字符。似乎发生的是，每次调用我的处理程序时，这些属性都在累积。因此，不是连续传递，而是连接到上一个节点的值。

I've got a really strange situation where my SAX ContentHandler is being handed bad Attributes by XMLReader. The document being parsed is UTF-8 with multi-byte characters inside XML attributes. What appears to happen is that these attributes are being accumulated each time my handler is called. So rather than being passed in succession, they get concatenated onto the previous node's value.

这里是一个使用公共数据（维基百科）

Here is an example which demonstrates this using public data (Wikipedia).

public class MyContentHandler extends org.xml.sax.helpers.DefaultHandler {

    public static void main(String[] args) {
        try {
            org.xml.sax.XMLReader reader = org.xml.sax.helpers.XMLReaderFactory.createXMLReader();
            reader.setContentHandler(new MyContentHandler());
            reader.parse("http://en.wikipedia.org/w/api.php?format=xml&action=query&list=allpages&apfilterredir=redirects&apdir=descending");

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

    public void startElement(String uri, String localName, String qName, org.xml.sax.Attributes attributes) {
        if ("p".equals(qName)) {
            String title = attributes.getValue("title");
            System.out.println(title);
        }
    }
}
