android使用XmlPullParser来解析XML文件

解析下面的一个XML：

<?xml version="1.0" encoding="utf-8" ?>
<rss><sid>77f265bb46de068e78f35afbadec62af</sid><count>3</count><control>0</control>
<mblog><uid>1195224593</uid><favid>3436952795</favid><mblogid>5xtaJR</mblogid><mblogidnum>3436952795</mblogidnum><mblogtype>0</mblogtype><mlevel>0</mlevel><feedid>5xtaJR</feedid><nick>马艳丽</nick><portrait>http://tp2.sinaimg.cn/1195224593/50/5614100014/0</portrait><vip>1</vip><vipsubtype>0</vipsubtype><member_type>13</member_type><remark></remark><level>2</level><rtnum>11</rtnum><commentnum>25</commentnum><attitudenum>0</attitudenum><attitudeid>0</attitudeid><attitudes_status>0</attitudes_status><attitudes_count>0</attitudes_count><mblogtypename></mblogtypename><visible><type>0</type><list_id>0</list_id></visible><content>婚礼在北海漂亮的北海公园举行…好美好浪漫的地方… </content><pic>http://ss12.sinaimg.cn/wap240/473dae11494344debfc5b</pic><time>1288852274</time><source>彩信</source></mblog></rss>

这样来写解析:

	public static Object[] getMBlogList(String content) throws HttpException {
		try {
			Object[] result = new Object[3];
			List<MBlog> lst = new ArrayList<MBlog>();
			result[1] = lst;

			final XmlPullParser parser = Xml.newPullParser();
			parser.setInput(new StringReader(content));
			int type;
			while ((type = parser.next()) != XmlPullParser.END_DOCUMENT) {
				switch (type) {
					<strong>case XmlPullParser.START_TAG:这里開始读取最外层的标签属性</strong>
						if (parser.getName().equals("count")) {
							try {
								result[0] = new Integer(parseText(parser));
							} catch (Exception e) {
								result[0] = 0;
							}
						} else if (parser.getName().equals("mblog")) {
							MBlog mb = parseMBlog(parser);
							if (mb != null)
								lst.add(mb);
						} else if (parser.getName().equals("relation")) {
							result[2] = new Integer(parseText(parser));
						}
						break;
					default:
						break;
				}
			}
			return result;
		} catch (NumberFormatException e) {
			throw new HttpException(e);
		} catch (XmlPullParserException e) {
			throw new HttpException(e);
		} catch (IOException e) {
			throw new HttpException(e);
		} catch (ParseException e) {
			throw new HttpException(e);
		}
	}
	
	private static String parseText(XmlPullParser parser) throws ParseException {
		try {
			int type = parser.next();
			if (type == XmlPullParser.TEXT) {
				return replaceEntityRef(parser.getText().trim());
			} else {
				return "";
			}
		} catch (Exception e) {
			throw new ParseException(PARSE_ERROR, e);
		}
	}
	
	public static MBlog parseMBlog(XmlPullParser parser) throws ParseException {
		<strong>MBlog b = new MBlog();//这里開始读取每一个MBlog对象</strong>
		try {
			int type;
			LOOP: {
				while ((type = parser.next()) != XmlPullParser.END_DOCUMENT) {
					switch (type) {
						case XmlPullParser.START_TAG:
							if (parser.getName().equals("uid")) {
								b.uid = parseText(parser);
								if (b.uid.equals(""))
									return null;
							} else if (parser.getName().equals("favid")) {
								b.favid = parseText(parser);
							} else if (parser.getName().equals("mblogid")) {
								b.mblogid = parseText(parser);
							} else if (parser.getName().equals("nick")) {
								String s = parseText(parser);
								b.nick = s;
							} else if (parser.getName().equals("portrait")) {
								b.portrait = parseText(parser);
							} else if (parser.getName().equals("vip")) {
								b.vip = (parseText(parser).equals("1")) ? true : false;
							} else if (parser.getName().equals("content")) {
								b.content = parseText(parser);
							} else if (parser.getName().equals("rtrootuid")) {
								b.rtrootuid = parseText(parser);
							} else if (parser.getName().equals("rtrootid")) {
								b.rtrootid = parseText(parser);
							} else if (parser.getName().equals("rtrootnick")) {
								String s = parseText(parser);
								b.rtrootnick = s;
							} else if (parser.getName().equals("rtrootvip")) {
								b.rtrootvip = (parseText(parser).equals("1")) ? true : false;
							} else if (parser.getName().equals("rtreason")) {
								b.rtreason = parseText(parser);
							} else if (parser.getName().equals("rtnum")) {
								b.rtnum = Integer.parseInt(parseText(parser));
							} else if (parser.getName().equals("commentnum")) {
								b.commentnum = Integer.parseInt(parseText(parser));
							} else if (parser.getName().equals("time")) {
								b.time = new Date(Long.parseLong(parseText(parser)) * 1000);
							} else if (parser.getName().equals("pic")) {
								b.pic = parseText(parser);
							} else if (parser.getName().equals("source")) {
								b.src = parseText(parser);
							} else if (parser.getName().equals("longitude")) {
								b.longitude = parseText(parser);
							} else if (parser.getName().equals("latitude")) {
								b.latitude = parseText(parser);
							}
							break;
						case XmlPullParser.END_TAG:
							if (parser.getName().equals("mblog")) {
								break LOOP;
							}
							break;
						default:
							break;
					}
				}
			}
			return b;
		} catch (Exception e) {
			throw new ParseException(PARSE_ERROR, e);
		}
	}
	

在Activity中这样调用:

public void parseAssertData() {
		InputStream is = null;
		try {
			is = this.getAssets().open("11.xml", Context.MODE_PRIVATE);
			int length = is.available();
			byte[] buffer = new byte[length];
			is.read(buffer);
			String temp = new String(buffer);

			try {
				Object[] array = ParseData.getMBlogList(temp);
			} catch (HttpException e) {
				e.printStackTrace();
			}
			
		} catch (IOException ex) {
			ex.printStackTrace();
		}
	}
