android pull解析子节点问题

Qiqihar 2012-03-30 07:51:22

问题如下：
* weather.xml中的current_conditions，forecast_conditions这两个子节点内有相同的子节点 icon、condition，这种情况怎么解析？？？
这里只对子节点<forecast_conditions>下的节点内容进行了解析,注意代码的红色部分。

下面是xml文件和pull解析代码的实现，请大侠们帮忙。

xml文件:

<?xml version="1.0" encoding="utf-8"?>

<xml_api_reply version="1">

	<weather module_id="0" tab_id="0" mobile_row="0" mobile_zipped="1"

		row="0" section="0">

		<forecast_information>

			<city data="Beijing, Beijing" />

			<postal_code data="beijing" />

			<latitude_e6 data="" />

			<longitude_e6 data="" />

			<forecast_date data="2012-03-30" />

			<current_date_time data="2012-03-30 20:30:00 +0000" />

			<unit_system data="SI" />

		</forecast_information>

		<current_conditions>

			<condition data="晴" />

			<temp_f data="55" />

			<temp_c data="13" />

			<humidity data="湿度： 12%" />

			<icon data="/ig/images/weather/sunny.gif" />

			<wind_condition data="风向： 北、风速：9 米/秒" />

		</current_conditions>

		<forecast_conditions>

			<day_of_week data="周五" />

			<low data="2" />

			<high data="13" />

			<icon data="/ig/images/weather/mostly_sunny.gif" />

			<condition data="以晴为主" />

		</forecast_conditions>

		<forecast_conditions>

			<day_of_week data="周六" />

			<low data="1" />

			<high data="14" />

			<icon data="/ig/images/weather/sunny.gif" />

			<condition data="晴" />

		</forecast_conditions>

		<forecast_conditions>

			<day_of_week data="周日" />

			<low data="1" />

			<high data="8" />

			<icon data="/ig/images/weather/mostly_sunny.gif" />

			<condition data="以晴为主" />

		</forecast_conditions>

		<forecast_conditions>

			<day_of_week data="周一" />

			<low data="2" />

			<high data="15" />

			<icon data="/ig/images/weather/mostly_sunny.gif" />

			<condition data="以晴为主" />

		</forecast_conditions>

	</weather>

</xml_api_reply>

pull解析方法：

public List<Other> getXml(InputStream in) throws IOException {



		try {

			// 声明XmlPullParserFactory

			XmlPullParserFactory factory = XmlPullParserFactory.newInstance();

			// 通过XmlPullParserFactory获取XmlPullParser

			XmlPullParser parser = factory.newPullParser();

			

			List<Other> others = null;

			Other other = null;

			// 设置InputStream用于解析

			parser.setInput(in, "utf-8");

			// 标签状态

			int event = parser.getEventType();



			while (event != XmlPullParser.END_DOCUMENT) {

				String nodeName = parser.getName();

				switch (event) {

				// xml开始

				case XmlPullParser.START_DOCUMENT:

					others = new ArrayList<Other>();

					break;

				

				case XmlPullParser.START_TAG:

					if (nodeName.equals("forecast_conditions")) {

						other = new Other();

					} 

					if (nodeName.equals("day_of_week")) {

						other.setDay(parser.getAttributeValue(0));

					} 

					// ===============取消注释后报NullpointerException=============

					//if (nodeName.equals("icon")) {

					//	other.setOurl(parser.getAttributeValue(0));

					//} 

					if (nodeName.equals("low")) {

						other.setLow(parser.getAttributeValue(0));

					} 

					if (nodeName.equals("high")) {

						other.setHigh(parser.getAttributeValue(0));

					} 

					// ===============取消注释后报NullpointerException===============

					//if (nodeName.equals("condition")) {

					//	other.setOcondition(parser.getAttributeValue(0));

					//}

					break;

				

				// 结束

				case XmlPullParser.END_TAG:

					if (nodeName.equals("forecast_conditions") && other != null) {

						others.add(other);

						other = null;

					} else {

						System.out.println("other = null");

					}

					break;

				default:

					break;

				}

				// event下移继续循环

				event = parser.next();

			}

			return others;



		} catch (XmlPullParserException e) {

			// TODO Auto-generated catch block

			e.printStackTrace();

		}



		return null;
