如何在JQuery中选择以下内容？

<div class='A'>
  <span class='B C'>
     <p class='C D E'>
     </p>
  </span>

以下内容尚无效。

$('div.A > span.B.C > p.C.D.E')

public class GeofenceTransitionsIntentService extends IntentService { ... @Override protected void onHandleIntent(Intent intent) { ... if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_ENTER) { //Create WiFi scan receiver WiFiScanReceiver wifiScan = new WiFiScanReceiver(); registerReceiver(wifiScan, new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION)); //Scan WifiManager wm = (WifiManager) getSystemService(Context.WIFI_SERVICE); Boolean scanStarted = wm.startScan(); } } ：获取当前匹配元素集中每个元素的后代，由选择器，jQuery对象或元素过滤。
