私はそれがどの形式であるかわかりませんが、私にはxmlのように見えます..方法は覚えていませんが、コードからではなく、そのWebページをいじって、このページからjsonのような情報を取得できました（変換器は使っていません）

{"resp": {"status": true, "version": "2.0", "artist": {"profile": "An Australian rock band, formed in 1973 by Angus and Malcolm Young, they teamed up with Dave Evans (vocals), Larry Van Kriedt (bass) and Colin Burgess (drums). In 1974 both Larry Van Kriedt and Colin Burgess left and were replaced by Rob Bailey (bass) and Peter Clack (drums), a further change in 1974 saw Peter Clack leave and Tony Currenti (drums) join the band. In June 1974 they were signed by Harry Vanda & George Young (Malcolm & Angus's brother) to Albert Productions. In November 1974, Dave Evans left the band and was replaced by Bon Scott (vocals & bagpipes). Rob Bailey also left in 1974 and was replaced by George Young (bass). In 1975 Phil Rudd (drums) replaced Tony Currenti and Mark Evans (bass) replaced George Young.  In June 1977 Mark Evans left and is replaced by Cliff Williams (bass) for their first tour of the USA. On the 19 Feb 1980 Bon Scott died at the age of 33. Brian Johnson (ex Geordie) joined the band to replace him on vocals and the album \"Back In Black\" was released, a tribute to Bon Scott, this album became the 2nd largest selling album of all time with over 40 million copies sold worldwide. In May 1983, Phil Rudd had a parting of the ways and was replaced by Simon Wright (drums), aged 20 then. November 1989 Simon Wright left and is replaced by Chris Slade (ex Manfred Mann's Earth Band, Uriah Heep & The Firm).

しかし、単にリンクをクリックしようとすると、xmlファイルのように見えます....それが何であれ...私は両方の形式を保存し、一度xml情報を取得しようとし、一度json情報を取得しようとしました.. ..xmlは私のために働いた..私は次のコードを使用しましたが、それは機能しました...しかし、問題は....リンクから直接情報を取得しようとすると....何も得られません.誰かがそのリンクから何かを取得できますか?私は完全に混乱しています.jsonまたはxmlを取得する必要がありますか?

Document doc = builder.parse("D:/workspace1/dd.xml");/////android_asset/www/dd.xml
XPathFactory xPathfactory = XPathFactory.newInstance();
XPath xpath = xPathfactory.newXPath();
XPathExpression expr = xpath.compile("//resp/artist/images/image[@uri]");
NodeList nl = (NodeList) expr.evaluate(doc, XPathConstants.NODESET);

for (int zzz = 0; zzz < nl.getLength(); zzz++)
{
    Node currentItem = nl.item(zzz);
    String key = currentItem.getAttributes().getNamedItem("uri").getNodeValue();
    System.out.println(key);
}

また、上記のコードは Android では機能しません (Java では正常に機能します)。(エラーをなくすには、try/catch で囲む必要があります)

また、jsonファイルとして保存したときに、このコードを試しましたが機能しませんでした

HttpPost httppost = new HttpPost("file://D:/workspace1/dd.json");

httppost.setHeader("Content-type", "application/json");

InputStream inputStream = null;

try {
    HttpResponse response = httpclient.execute(httppost);           
    HttpEntity entity = response.getEntity();
    String result=null;
    inputStream = entity.getContent();
    // json is UTF-8 by default
    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"), 8);
    StringBuilder sb = new StringBuilder();

    String line = null;
    while ((line = reader.readLine()) != null)
    {
        sb.append(line + "\n");
    }
    result = sb.toString();
    TV.setText(result);
    Bundle jObject = null;
    String aJsonString = jObject.getString("status");
     TV.setText( aJsonString);
} catch (Exception e) { 
    Log.e("MYAPP", "exception", e);
}
finally {
    try{if(inputStream != null)inputStream.close();}catch(Exception squish){}
}
