解析Android中的索引XML

Question

如何解析本地XML文件以便能夠將其字符串值放入TextView.setText(String)方法中？我的本地XML文件看起來是這樣的：

<quran> 
<sura index="1" name="الفاتحة"> 
    <aya index="1" text="In the name of Allah, the Entirely Merciful, the Especially Merciful."/> 
    <aya index="2" text="[All] praise is [due] to Allah, Lord of the worlds -"/> 
    <aya index="3" text="The Entirely Merciful, the Especially Merciful,"/> 
    <aya index="4" text="Sovereign of the Day of Recompense."/> 
    <aya index="5" text="It is You we worship and You we ask for help."/> 
    <aya index="6" text="Guide us to the straight path -"/> 
    <aya index="7" text="The path of those upon whom You have bestowed favor, not of those who have evoked [Your] anger or of those who are astray."/> 
</sura> 
<sura index="2" name="البقرة"> 
    <aya index="1" text="Alif, Lam, Meem."/> 
    <aya index="2" text="This is the Book about which there is no doubt, a guidance for those conscious of Allah -"/> 
    <aya index="3" text="Who believe in the unseen, establish prayer, and spend out of what We have provided for them,"/> 
    <aya index="4" text="And who believe in what has been revealed to you, [O Muhammad], and what was revealed before you, and of the Hereafter they are certain [in faith]."/> 
    <aya index="5" text="Those are upon [right] guidance from their Lord, and it is those who are the successful."/> 

我希望能夠訪問特定的位於特定AYH索引編號文本字符串，但我不知道如何做到這一點，因爲對中的每個對象綾一個sura對象有兩個東西，索引和我想要訪問的文本。請幫忙！

如果您確實想要使用XmlPullParser，請按照Harsh的建議，查看[docs] [1]中類概覽中給出的示例。

它的「文本」屬性，你要那麼你應該使用方法XmlPullParser.getAttributeValue(null, "text")「綾」的元素，如下圖所示：

XmlPullParserFactory factory = XmlPullParserFactory.newInstance(); 
factory.setNamespaceAware(true); 
XmlPullParser xpp = factory.newPullParser(); 

xpp.setInput(new StringReader ("<quran><sura index=\"1\" name=\"الفاتحة\"><aya index=\"1\" text=\"In the name of Allah, the Entirely Merciful, the Especially Merciful.\"/><aya index=\"2\" text=\"[All] praise is [due] to Allah, Lord of the worlds -\"/><aya index=\"3\" text=\"The Entirely Merciful, the Especially Merciful,\"/><aya index=\"4\" text=\"Sovereign of the Day of Recompense.\"/><aya index=\"5\" text=\"It is You we worship and You we ask for help.\"/><aya index=\"6\" text=\"Guide us to the straight path -\"/><aya index=\"7\" text=\"The path of those upon whom You have bestowed favor, not of those who have evoked [Your] anger or of those who are astray.\"/></sura><sura index=\"2\" name=\"البقرة\"><aya index=\"1\" text=\"Alif, Lam, Meem.\"/><aya index=\"2\" text=\"This is the Book about which there is no doubt, a guidance for those conscious of Allah -\"/><aya index=\"3\" text=\"Who believe in the unseen, establish prayer, and spend out of what We have provided for them,\"/><aya index=\"4\" text=\"And who believe in what has been revealed to you, [O Muhammad], and what was revealed before you, and of the Hereafter they are certain [in faith].\"/><aya index=\"5\" text=\"Those are upon [right] guidance from their Lord, and it is those who are the successful.\"/></sura></quran>")); 
int eventType = xpp.getEventType(); 
while (eventType != XmlPullParser.END_DOCUMENT) { 
    if(eventType == XmlPullParser.START_DOCUMENT) { 
     Log.i(getClass().getName(), "Start document"); 
    } else if(eventType == XmlPullParser.START_TAG) { 
     Log.i(getClass().getName(), "Start tag "+xpp.getName()); 
     if(xpp.getName().equals("aya")){ 
      Log.i(getClass().getName(), "aya text: " + xpp.getAttributeValue(null, "text")); 
     } 
    } else if(eventType == XmlPullParser.END_TAG) { 
     System.out.println("End tag "+xpp.getName()); 
     Log.i(getClass().getName(), "End tag "+xpp.getName()); 
    } else if(eventType == XmlPullParser.TEXT) { 
     System.out.println("Text "+xpp.getText()); 
     Log.i(getClass().getName(), "Text "+xpp.getText()); 
    } 
    eventType = xpp.next(); 
} 
Log.i(getClass().getName(), "End document");
