将XML从网站解析为Android设备

Question

我正在启动一个Android应用程序,它将从Web解析XML.我已经创建了一些Android应用程序,但他们从未涉及解析XML,我想知道是否有人有关于最佳方式的任何提示？

这是一个例子:

        try {
            URL url = new URL(/*your xml url*/);
            URLConnection conn = url.openConnection();

            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();
            Document doc = builder.parse(conn.getInputStream());

            NodeList nodes = doc.getElementsByTagName(/*tag from xml file*/);
            for (int i = 0; i < nodes.getLength(); i++) {
                Element element = (Element) nodes.item(i);
                NodeList title = element.getElementsByTagName(/*item within the tag*/);
                Element line = (Element) title.item(0);
                phoneNumberList.add(line.getTextContent());
            }
        }
        catch (Exception e) {
            e.printStackTrace();
        }

在我的示例中,我的XML文件看起来有点像:

<numbers>
   <phone>
      <string name = "phonenumber1">555-555-5555</string>
   </phone>
   <phone>
      <string name = "phonenumber2">555-555-5555</string>
   </phone>
</numbers>

我会/*tag from xml file*/用"phone"和/*item within the tag*/"string" 替换.
