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。
