菜鸟的安卓实习之路----解析网络XML文件

1 建立网络连接，获取xml输入流

                URL url = new URL(urladdr);
                HttpURLConnection connection = (HttpURLConnection) url.openConnection();
                connection.connect();
                connection.setConnectTimeout(20000);
                InputStream inStream = connection.getInputStream();

最后别忘了关闭输入流和连接

                inStream.close();
                connection.disconnect();

在这中间进行XML解析

2 解析

<span style="white-space:pre">		</span>HashMap<String, String> hashMap = new HashMap<String, String>();
		DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
		DocumentBuilder builder = factory.newDocumentBuilder();
		Document document = builder.parse(inStream);
		Element root = document.getDocumentElement();
		NodeList childNodes = root.getChildNodes();
		for (int j = 0; j < childNodes.getLength(); j++)
		{
			Node childNode = (Node) childNodes.item(j);
			if (childNode.getNodeType() == Node.ELEMENT_NODE)
			{
				Element childElement = (Element) childNode;
				hashMap.put(childElement.getNodeName(),childElement.getFirstChild().getNodeValue());
			}
		}
		return hashMap;

这里用到的事宜hashMap来存储内容。
