java 用dom的方式解析xml文件，子节点下有相同名字的子节点？

如下图所示第一级含有1，2，3，4 等多个节点，
1下面含有1.1，1.2，1.3，1.4，1.5 等多个节点，
1.2下面含有1.2.1，1.2.2 等多个节点，
解析代码如下：
标注的此处有问题的，testSublist的长度，包括了1.1到1.5和1.2.1到1.2.2，也就是也就是统计出了1下面所有出现了IMPLEMENTATION-DATA-TYPE-ELEMENT，现在我只希望，获得的长度为5，也就是1.1到1.5，也就是一级一级获取下去？？

NodeList testList = doc.getElementsByTagName("IMPLEMENTATION-DATA-TYPE");
for(int i = 0; i < impList.getLength(); i++) {
            Element testElement = (Element) testList.item(i);   
            NodeList testSublist=testElement.getElementsByTagName("IMPLEMENTATION-DATA-TYPE-ELEMENT"); //此处有问题
for (int ii = 0; ii < testSublist.getLength(); ii++) {
}
}

兄弟,还在纠结这个问题呀;
自己实现个getChildrenByTagName,再结合我上次给你的代码
看下面代码:

    public static List<Node> getChildrenByTagName(Node nl, String name) {
        List<Node> nodeList = new ArrayList<Node>();
        for (Node child = nl.getFirstChild(); child != null; child = child.getNextSibling()) {
            if(child.getNodeType() == Node.ELEMENT_NODE && 
                name.equals(child.getNodeName())){
                nodeList.add(child);
            }
        }
        return nodeList;
    }

        public static void main(String[] args) {

        DocumentBuilderFactory docbf = DocumentBuilderFactory.newInstance();
        try {
            DocumentBuilder docb = docbf.newDocumentBuilder();
            Document doc = docb.parse("test.xml");
            List<Node> elements = getChildrenByTagName(doc, "IMPLEMENTATION-DATA-TYPE");
            System.out.println(elements);
        } catch (ParserConfigurationException e) {
            e.printStackTrace();
        } catch (SAXException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

package com.test;

public class DomXML {

    public static void main(String[] args) {
        try {
            File file = new File("e:/People.xml");  
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();   
            DocumentBuilder builder = factory.newDocumentBuilder();   
            Document document = builder.parse(file);   
            Element element = document.getDocumentElement();

            List<People> peopleList = new ArrayList<People>();
            NodeList peopleNodes = element.getElementsByTagName("People");

                NodeList childPeopleNodes = peopleElement.getChildNodes();
                for(int j=0;j<childPeopleNodes.getLength();j++){
                    //DOM解析时候注意子节点前面的空格也会被解析
                    if(childPeopleNodes.item(j) instanceof Element){
                        Element childPeopleElement = (Element) childPeopleNodes.item(j);
                        if(childPeopleElement.getNodeType()==Node.ELEMENT_NODE){  
                            if(childPeopleElement.getNodeName().equals("Name")){
                                people.setEnglishName(childPeopleElement.getAttribute("en"));
                                people.setName(childPeopleElement.getTextContent());
                            }
                            else if(childPeopleElement.getNodeName().equals("Age")){
                                people.setAge(childPeopleElement.getTextContent());    
                            }
                        }
                    }
                }
                peopleList.add(people);
            }

            for(People people : peopleList){
                System.out.println(people.getId()+"\t"+people.getName()+"\t"+people.getEnglishName()+"\t"+people.getAge());
            }

        } catch (Exception e) {
            // TODO 自动生成的 catch 块
            e.printStackTrace();
        } 


    }
}

使用getChildNodes

        NodeList testList = doc.getElementsByTagName("IMPLEMENTATION-DATA-TYPE");
        for (int i = 0; i < impList.getLength(); i++) {
            Element testElement = (Element) testList.item(i);
            NodeList testSublist = testElement.getChildNodes();
            for (int ii = 0; ii < testSublist.getLength(); ii++) {
            }
        }
