解析XML和后删除所有字符放大器;放大器; [英] Parsing XML dropping all characters after &

问题描述

我创建一些解析XML和在ListView显示它的应用程序。在我的XML的几个项目包括＆安培; 如此我已经逃脱他们这样＆放大器;放大器; 这是工作正确的一些设备和仿真器。

I am creating an app that parses some XML and display it in a ListView. A few items in my xml contain &s so I have escaped them like this & It is working correctly on a few devices and on the emulator.

但在两个设备（三​​星Sidekick的4克API 2.2，而三星Replish API 2.3.6），它是失败的。一切＆放大器后，放大器; 被神奇地消失了。

But on two devices (Samsung Sidekick 4g API 2.2, and Samsung Replish API 2.3.6) it is failing. Everything after the & gets magically disappeared.

下面是在XML的项目给我的麻烦：

Here is the item in the XML giving me trouble:

<site>
    <name>English Language &amp; Usage</name>
    <link>http://english.stackexchange.com/</link>
    <about>English Language &amp; Usage Stack Exchange is a question and answer site for linguists, etymologists, and serious English language enthusiasts.</about>

下面是解析code的肉：

Here is the "meat" of the parsing code:

private static String getValue(Element item, String str) {
    NodeList n = item.getElementsByTagName(str);
    Log.i("StackSites", ""+getElementValue(n.item(0)));
    return getElementValue(n.item(0));
}

private static String getElementValue( Node elem ) {
         Node child;
         if( elem != null){
             if (elem.hasChildNodes()){
                 for( child = elem.getFirstChild(); child != null; child = child.getNextSibling() ){
                     if( child.getNodeType() == Node.TEXT_NODE  ){
                         return child.getNodeValue();
                     }
                 }
             }
         }
         return "";
  }

在某些设备（LG擎天柱G，摩托Attrix 2，和几个模拟器）这个工作正常并且出来是这样的：

On some devices (LG Optimus G, Moto Attrix 2, and a few emulators) this works correctly and comes out like this:

不过上，我试过两个三星设备的getValue（）方法只返回＆功放之前出现的文本;放大器; 这样的结果是这样的：

However on the two Samsung devices that I've tried getValue() method returns only the text that comes before the & so the result is this:

推荐答案

这是因为你不看的其余节点。实体获得一个不同的节点，之后该实体之后的文本获取的节点。您立即返回 - 你需要连接你的结果。

That's because you aren't looking at the rest of the nodes. The entity gets a different node, and the text following the entity gets the node after that. You are returning immediately -- you need to concatenate your results.
