解析XML時，標簽異常不匹配

Question

這已經成為我背面的真正痛苦。

我要解析的URL是http://torrentz.eu/feed_verifiedP?q=ubuntu

這是xml的簡短版本：

<?xml version="1.0"?>
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">
 <channel>
  <title>Torrentz - ubuntu</title>
  <link>http://torrentz.eu/verified?q=ubuntu</link>
  <description>ubuntu search</description>
  <language>en-us</language>
  <atom:link href="http://torrentz.eu/feed_verifiedP?q=ubuntu" rel="self" type="application/rss+xml" />
  <item>
     <title>ubuntu 11 10 desktop i386 iso</title>
     <link>http://torrentz.eu/8ac3731ad4b039c05393b5404afa6e7397810b41</link>
     <guid>http://torrentz.eu/8ac3731ad4b039c05393b5404afa6e7397810b41</guid>

  </item>
 </channel>
</rss>

我的代碼：

    SAXParserFactory spf = SAXParserFactory.newInstance();
    SAXParser sp = spf.newSAXParser();
    XMLReader xr = sp.getXMLReader();

    //Get Torrents
    XMLTorrentsRSSHandler torrentsHandler = new XMLTorrentsRSSHandler();
    xr.setContentHandler(torrentsHandler);
    InputStream in = url.openStream();
    xr.parse(new InputSource(in));
    XMLTorrentsRSSParsedDataSet parsedTorrentsDataSet = torrentsHandler.getParsedData();

我不斷收到此異常：

org.apache.harmony.xml.ExpatParser$ParseException: At line 1, column 53: mismatched tag

為什么翻轉會像這樣折磨我！？

編輯：這種方法直到今天工作良好。 也許網站改變了，但是這個圖釘的不匹配標簽在哪里？

為什么在構建路徑上實現和諧？ 您的代碼可以與Oracle JDK7u3中的內置SAXParser一起正常工作。 如果沒有理由使用和聲實現，則應恢復為標准實現。

測試用例形式：

import java.io.IOException;
import java.io.StringReader;

import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

import org.xml.sax.Attributes;
import org.xml.sax.ContentHandler;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
import org.xml.sax.XMLReader;
import org.xml.sax.helpers.DefaultHandler;

class Scratch {
    public static void main(String[] args) throws IOException, SAXException, ParserConfigurationException {
        final String document = "<?xml version=\"1.0\"?>\n" +
                "<rss version=\"2.0\" xmlns:atom=\"http://www.w3.org/2005/Atom\">\n" +
                " <channel>\n" +
                "  <title>Torrentz - ubuntu</title>\n" +
                "  <link>http://torrentz.eu/verified?q=ubuntu</link>\n" +
                "  <description>ubuntu search</description>\n" +
                "  <language>en-us</language>\n" +
                "  <atom:link href=\"http://torrentz.eu/feed_verifiedP?q=ubuntu\" rel=\"self\" type=\"application/rss+xml\" />\n" +
                "  <item>\n" +
                "     <title>ubuntu 11 10 desktop i386 iso</title>\n" +
                "     <link>http://torrentz.eu/8ac3731ad4b039c05393b5404afa6e7397810b41</link>\n" +
                "     <guid>http://torrentz.eu/8ac3731ad4b039c05393b5404afa6e7397810b41</guid>\n" +

        SAXParserFactory spf = SAXParserFactory.newInstance();
        SAXParser sp = spf.newSAXParser();
        XMLReader xr = sp.getXMLReader();

        ContentHandler torrentsHandler = new DefaultHandler() {
            @Override
            public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
                System.out.printf("%s / %s / %s\n", uri, localName, qName);
            }
        };
        xr.setContentHandler(torrentsHandler);
        xr.parse(new InputSource(new StringReader(document)));
    }
}
