java - OSM xml 损坏？

Question

我已经下载了 OSM 世界地图。解析时出现异常:

osm

(...)

Exception in thread "main" org.xml.sax.SAXParseException; lineNumber: 3682; columnNumber: 140; XML-Dokumentstrukturen müssen innerhalb derselben Entity beginnen und enden.

我的代码是:

public class OSMReader {
    public static void main(String[] args) throws IOException, SAXException, ParserConfigurationException {
        BZip2CompressorInputStream bic = new BZip2CompressorInputStream(new FileInputStream(new File("X:\\Medien\\Karten\\planet-200309.osm.bz2")));
        SAXParserFactory spf = SAXParserFactory.newInstance();
        spf.newSAXParser().parse(bic, new DefaultHandler() {
            @Override
            public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
                System.out.println(qName);
            }
        });
        bic.close();
    }
}

我非常确定 OSM 能够生成有效的 XML 文件。

XML 文件本身太大，无法确认问题。

知道如何成功解析 XML 吗？

编辑

我尝试读取 xml 中的行:

public class OSMReader {
    public static void main(String[] args) throws IOException, SAXException, ParserConfigurationException {
        BZip2CompressorInputStream bic = new BZip2CompressorInputStream(new FileInputStream(new File("X:\\Medien\\Karten\\planet-200309.osm.bz2")));
        BufferedReader br = new BufferedReader(new InputStreamReader(bic));
        int i = 0;
        while (i++ < 3685) {
            String line = br.readLine();
            if (i > 3680) {
                System.out.println(line);
            }
        }
        bic.close();
    }
}

什么给了我这个输出:

 <changeset id="3678" created_at="2008-06-01T01:18:46Z" closed_at="2008-06-01T02:47:15Z" open="false" user="mawis" uid="37850" min_lat="49.1950155" min_lon="9.2284944" max_lat="49.2049970" max_lon="9.2458586" num_changes="154" comments_count="0"/>

我检查了 MD5 哈希值，它们匹配:

Answer 1

我必须向 BZip2CompressorInputStream 的构造函数添加 , true。
