简单地解析dom字符串(dom4j)

package October;

import java.util.Iterator;
import java.util.List;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;

public class DOMTest {

	public static void main(String[] args) {

		String v_strXML = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><scheme><normal><time><start>08:30</start><end>12:00</end></time><time><start>13:30</start><end>17:30</end></time></normal><weekend><saturday><rest>1</rest></saturday><sunday><rest>1</rest></sunday></weekend><special><workday><date>2009-02-27</date></workday><holiday><date>2009-04-22</date></holiday><holiday><date>2009-04-26</date></holiday><workday><date>2009-04-28</date><time><start>10:00</start><end>12:00</end></time></workday><holiday><date>2009-04-29</date></holiday><workday><date>2009-04-30</date><time><start>10:30</start><end>17:00</end></time></workday></special></scheme>";

		Document doc = null;
		try {
			doc = DocumentHelper.parseText(v_strXML);
		} catch (DocumentException e2) {
			e2.printStackTrace();
		}
		Element root = doc.getRootElement();// 指向根节点

		// normal解析
		Element normal = root.element("normal");
		try {

			for (int i = 0; i < lstTime.size(); i++) {
				Element etime = (Element) lstTime.get(i);
				Element start = etime.element("start");
				Element end = etime.element("end");
				System.out
						.println("start.getTextTrim()=" + start.getTextTrim());
				System.out.println("end.getTextTrim()=" + end.getTextTrim());
			}
		} catch (Exception e) {
			e.printStackTrace();
		}

		// weekend解析
		Element weekend = root.element("weekend");
		try {
			// 周6
			List lstSaturday = weekend.elements("saturday");// 所有的Item节点
			Iterator Itr1 = lstSaturday.iterator();
			while (Itr1.hasNext()) {

			// 周日
			List lstSunday = weekend.elements("sunday");// 所有的Item节点
			Iterator Itr2 = lstSunday.iterator();
			while (Itr2.hasNext()) {
				Element eSunday = (Element) Itr2.next();// 一个Item节点
				Element rest = eSunday.element("rest");
				System.out.println("周日休息" + rest.getTextTrim());
			}
		} catch (Exception e) {
			e.printStackTrace();
		}

		// special解析
		Element special = root.element("special");
		try {
			// 特殊工作日workday
			List lstWorkday = special.elements("workday");// 所有的Item节点
			Iterator Itr1 = lstWorkday.iterator();
			while (Itr1.hasNext()) {
				Element eWorkday = (Element) Itr1.next();// 一个Item节点
				Element date = eWorkday.element("date");
				System.out.println("特殊工作日===" + date.getText());
				List time = eWorkday.elements("time");
				Iterator Itr2 = time.iterator();

					Element end = etime.element("end");
					System.out.println("特殊开始时间" + start.getTextTrim());
					System.out.println("特殊结束时间" + end.getTextTrim());
				}
			}

			// 节假日holiday
			List lstHoliday = special.elements("holiday");// 所有的Item节点
			Iterator Itr3 = lstHoliday.iterator();
			while (Itr3.hasNext()) {
				Element eHoliday = (Element) Itr3.next();// 一个Item节点
				Element date = eHoliday.element("date");
				System.out.println("节假日===" + date.getTextTrim());
			}

		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

 以上dom的字符串如下：

<?xml version="1.0" encoding="UTF-8"?>
<scheme>
	<normal>
		<time>
			<start>08:30</start>
			<end>12:00</end>
		</time>
		<time>
			<start>13:30</start>
			<end>17:30</end>
		</time>
	</normal>
	<weekend>
		<saturday>
			<rest>1</rest>
		</saturday>
		<sunday>
			<rest>1</rest>
		</sunday>
	</weekend>
	<special>
		<workday>
			<date>2009-02-27</date>
		</workday>
		<holiday>
			<date>2009-04-22</date>
		</holiday>
		<holiday>
			<date>2009-04-26</date>
		</holiday>
		<workday>
			<date>2009-04-28</date>
			<time>
				<start>10:00</start>
				<end>12:00</end>
			</time>
		</workday>
		<holiday>
			<date>2009-04-29</date>
		</holiday>
		<workday>
			<date>2009-04-30</date>
			<time>
				<start>10:30</start>
				<end>17:00</end>
			</time>
		</workday>
	</special>
</scheme>

 

本例子需要导入dom4j的包，本实例为dom4j-1.6.1.jar。 

运行结果如下：

start.getTextTrim()=08:30
end.getTextTrim()=12:00
start.getTextTrim()=13:30
end.getTextTrim()=17:30
周六休息1
周日休息1
特殊工作日===2009-02-27
特殊工作日===2009-04-28
特殊开始时间10:00
特殊结束时间12:00
特殊工作日===2009-04-30
特殊开始时间10:30
特殊结束时间17:00
节假日===2009-04-22
节假日===2009-04-26
节假日===2009-04-29
