Question

我正在尝试解析此XML文件，但START_TAG收到错误。我应该如何设置START_TAG到此XML文件的名称

org.xmlpull.v1.XmlPullParserException: expected: START_TAG {null}rss version="2.0" (position:START_TAG <rss version='2.0'>@2:20 in java.io.InputStreamReader@3a7a4ee3)

public ArrayList<Article> parse(InputStream is) throws XmlPullParserException, IOException, ParseException {
    try {
        XmlPullParser parser = Xml.newPullParser();
        parser.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, false);
        parser.setInput(is, null);
        parser.nextTag();
        return readFeed(parser);
    } finally {
        is.close();
    }
}

private ArrayList<Article> readFeed(XmlPullParser parser) throws IOException, XmlPullParserException, ParseException {
    ArrayList<Article> articles = new ArrayList<>();
    parser.require(XmlPullParser.START_TAG,ns,"rss version=\"2.0\"");
    while (parser.next() != XmlPullParser.END_TAG) {
        if (parser.getEventType() != XmlPullParser.END_TAG) {
            continue;
        }
        String name = parser.getName();
        // Starts by looking for the entry tag
        if (name.equals("item")) {
            articles.add(readEntry(parser));
        } else {
            skip(parser);
        }
    }
    return articles;
}

这是XML文件的链接

想出我的START_TAG需要：

sm = difflib.SequenceMatcher(None,list(ya),list(yb))
sm.ratio()

我还需要另一个while循环

parser.require(XmlPullParser.START_TAG,ns,"rss");
    while (parser.next() != XmlPullParser.END_TAG)

在解析XML文件时，START_TAG的名称应该是什么？
