如上的一个xml。我想获得每一个Field节点的Name中的值和对应的value值，value分割成数组取第一个的值，最好用org.w3c.dom解析。

Answer 1

import java.io.File;
import java.util.Iterator;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

public class ParseXml {
	public static void main(String[] args) throws DocumentException {
		SAXReader reader = new SAXReader();
		Document doc = reader.read(new File("d:/test.xml"));
		Element root = doc.getRootElement();
		Element record = root.element("Record");
		Iterator<Element> it = record.elementIterator("Field");
		while (it.hasNext()) {
			Element element = it.next();
			Element name = element.element("Name");
			System.out.println(name.getText());
			Element value = element.element("Value");
			ParseXml.parseValue(value);
		}
	}

	public static void parseValue(Element value) {
		Iterator<Element> it = value.elementIterator();
		if (it.hasNext()) {
			while (it.hasNext()) {
				Element element = it.next();
				Element innerField = element.element("Field");
				Element innerName = innerField.element("Name");
				System.out.println(innerName.getText());
				Element innerValue = innerField.element("Value");
				parseValue(innerValue);
			}
		} else {
			System.out.println(value.getText());
		}
	}
}
