java - XML 解析期间字母显示不正确

Question

我正在尝试解析网站:http://www.cbr.ru/scripts/XML_daily.asp

SAXParserFactory factory = SAXParserFactory.newInstance ();
Parserhandler handler = new Parserhandler ();
SAXParser parser = factory.newSAXParser ();
InputSource is = new InputSource (  "http://www.cbr.ru/scripts/XML_daily.asp");
is.setEncoding ( "iso-8859-1");
parser.parse (is, handler);

一般来说，我会尝试不同的编码 utf-8、Cp1251 等变体。

但作为返回，我得到如下字符:

Þæíîàôðèêàíñêèõ ðýíäîâ

或者我收到错误

unknown encoding

请帮帮我。

Answer 1

也许您可以得到正确的字符，如下所示。

public void theMethod() {
    try {
        String uri = "http://www.cbr.ru/scripts/XML_daily.asp";

        ByteArrayInputStream bis = getByteArrayInputStreamOfUri(uri);
        parser.parse(bis, handler);
    } catch (...) {}
}

public ByteArrayInputStream getByteArrayInputStreamOfUri(String uri) {
    InputStream is = getInputStreamOfUrl(uri);
    if (is == null) {
        return null;
    }

    Scanner sc = new Scanner(is, "Windows-1451");
    StringBuilder sb = new StringBuilder();

    while (sc.hasNextLine()) {
        sb.append(sc.nextLine());
    }

    try {
        return new ByteArrayInputStream(sb.toString().getBytes("utf-8"));
    } catch (UnsupportedEncodingException e) {
        return null;
    }
}

private InputStream getInputStreamOfUrl(String uri) {
    try {
        URL url = new URL(uri);

        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("GET");
        connection.setRequestProperty("Accept", "application/xml");
        return connection.getInputStream();
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}
