咋遍历?取子节点? public NodeList getChildNodes()A NodeList that contains all children of this node. If there are no children, this is a NodeList containing no nodes. 要是网页上的话,就是document.childNodes
public static void main(String[] args) { Document d = null; if(d.hasChildNodes()) { parse(d); } }
public static void parse(Node parent) { NodeList list = parent.getChildNodes(); Node n; for(int i = 0; i < list.getLength(); i++) { n = list.item(i); if(n.hasChildNodes()) { parse(n); } } }
public Element getDocument(String filePath) { try { File file = getFile(filePath); saxReader = new SAXReader(); doc = saxReader.read(file); element = doc.getRootElement(); } catch (DocumentException e) { // TODO 自动生成 catch 块 e.printStackTrace(); } return element; }如此迭代 public DBConnection(String xPath) { MyDom4j dom4j = new MyDom4j(); e = dom4j.getDocument(xPath); for(Iterator it = e.elementIterator("connection");it.hasNext();) { element = (Element)it.next(); } this.url = element.elementText("url"); this.driver = element.elementText("driver"); this.password = element.elementText("pwd"); this.user = element.elementText("user"); }
Document doc = new SAXReader().read(new File(path + "\\daoContext.xml")); Element root = doc.getRootElement(); List el = root.elements(); for (Iterator it = el.iterator();it.hasNext() ; ) { Element em = (Element)it.next(); String id = em.attributeValue("id"); String impl = em.attributeValue("class"); Class implClazz = Class.forName(impl); Object obj = implClazz.newInstance(); daoMap.put(id , obj); }

不明白你的意思 是解析xml么?
给了例子不知道能不能解决你的问题 private static Document doc;
private static SAXReader saxReader;
private static Element element;
private static File getFile(String filePath)
{
File file = new File(filePath);
return file;
}
public Element getDocument(String filePath)
{
try {
File file = getFile(filePath);
saxReader = new SAXReader();
doc = saxReader.read(file);
element = doc.getRootElement();
} catch (DocumentException e) {
// TODO 自动生成 catch 块
e.printStackTrace();
}
return element;
}如此迭代 public DBConnection(String xPath)
{
MyDom4j dom4j = new MyDom4j();
e = dom4j.getDocument(xPath);
for(Iterator it = e.elementIterator("connection");it.hasNext();)
{
element = (Element)it.next();
}
this.url = element.elementText("url");
this.driver = element.elementText("driver");
this.password = element.elementText("pwd");
this.user = element.elementText("user");
}
Element root = doc.getRootElement();
List el = root.elements();
for (Iterator it = el.iterator();it.hasNext() ; )
{
Element em = (Element)it.next();
String id = em.attributeValue("id");
String impl = em.attributeValue("class");
Class implClazz = Class.forName(impl);
Object obj = implClazz.newInstance();
daoMap.put(id , obj);
}
