如何訪問從nodelist中增加by1的childnode android

我想使用nodelist從XML文件中檢索數據，但問題是我有圖像屬性，它是增量如何獲得此屬性如何訪問此這裏即將放置我的xml文件，這樣你們可以容易理解如何訪問從nodelist中增加by1的childnode android

看到這裏，以1在此增加有PHOTO_URL圖像屬性我想訪問艾德里安如何訪問PHOTO_URL

更好的解決方案是在表單中使用更清晰的XML ...... 在這種情況下，您將能夠像XStream一樣使用pull paerser和數據綁定來輕鬆地將您的xml轉換爲java bean。

如果修復XML結構不是一個選項，您可以將來自節點的所有子節點與node.getChildNodes（）合併，並按類型和名稱過濾此列表。

PS：XML解析usind DOM是如此的00 - 我們現在拉解析其consimes少得多記憶，更容易hanldle
