Android 解析XML文件和生成XML文件,androidxml


解析XML文件

public static void initXML(Context context) {
        //can't create in /data/media/0 because permission 
        //can create in /sdcard/hotel
        File mSettings = new File(HOTEL_PATH_XML);
        if (!mSettings.exists()) {
            mSettings.mkdirs();
        }
        File settings = new File(mSettings,"settings.xml");
        Log.i("XmlPullParser-----settings", settings+"+1+");
        if (!settings.exists()) {
            try {
                Log.i("XmlPullParser-----settings", settings+"+2+");
                settings.createNewFile();
                initSettings(settings);
            } catch (IOException e) {
                e.printStackTrace();
                return;
            }
            return;
        }
        
        try {
            XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
            factory.setNamespaceAware(true);
            XmlPullParser xpp = factory.newPullParser();
            xpp.setInput(new FileInputStream(settings), "utf-8");
            int eventType = xpp.getEventType();
            while (eventType != XmlPullParser.END_DOCUMENT) {
                Log.i("XmlPullParser-----TAG", eventType+"");
                if (eventType == XmlPullParser.START_TAG) {
                    String tag = xpp.getName();
                    Log.i("XmlPullParser-----TAG", "tag---------"+tag+"");
                    if (tag.equals("item")) {
                        String id = xpp.getAttributeValue(null, "id");
                        String value = xpp.getAttributeValue(null, "value");
                        if (id.equals("server")) {
                            sServerAddr = value;
                        } else if (id.equals("hotel")) {
                            sHid = value;
                        } else if (id.equals("room")) {
                            sRoomNum = value;
                        }
                    }
                }
                eventType = xpp.next();
            }
            Log.i("XmlPullParser-----TAG", eventType+"exist the xunhuan");
        } catch (XmlPullParserException e) {
            e.printStackTrace();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

生成XML文件

//默認是沒有換行的
public static void initSettings(final File settings) { new Thread(new Runnable() { @Override public void run() { FileOutputStream fos = null; try { fos = new FileOutputStream(settings); XmlSerializer serializer = Xml.newSerializer(); serializer.setOutput(fos, "UTF-8"); serializer.startDocument("UTF-8", true); serializer.startTag(null, "config"); serializer.startTag(null, "category"); serializer.attribute(null, "name", "hot"); // server serializer.startTag(null, "item"); serializer.attribute(null, "id", "server"); serializer.attribute(null, "value", ""); serializer.endTag(null, "item"); // hid serializer.startTag(null, "item"); serializer.attribute(null, "id", "hotel"); serializer.attribute(null, "value", ""); serializer.endTag(null, "item"); // room serializer.startTag(null, "item"); serializer.attribute(null, "id", "room"); serializer.attribute(null, "value", ""); serializer.endTag(null, "item"); serializer.endTag(null, "category"); serializer.endTag(null, "config"); serializer.endDocument(); serializer.flush(); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IllegalArgumentException e) { e.printStackTrace(); } catch (IllegalStateException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally { if (fos != null) { try { fos.close(); } catch (IOException e) { e.printStackTrace(); } } } } }).start(); }
