DOM解析类

package com.analysisxml.ych.analysisxml.utils;
import android.util.Log;
import com.analysisxml.ych.analysisxml.entity.Hello;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;
import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
public class Dom {
    public Hello domToxml(InputStream is) throws ParserConfigurationException, IOException, SAXException {

        //初始化
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        //获得Document对象
Document document = builder.parse(is);
        //获得Hello的list
NodeList helloList = document.getElementsByTagName("dict");
        //遍历Hello标签
NodeList nodeList = helloList.item(0).getChildNodes();
        Hello hello = new Hello();
        List<String> psList = new ArrayList<>();
        List<String> pronList = new ArrayList<>();
        List<String> posList = new ArrayList<>();
        List<String> acceptationList = new ArrayList<>();
        for (int i = 0; i < nodeList.getLength(); i++) {
            if ("key".equals(nodeList.item(i).getNodeName())) {
                hello.setKey(nodeList.item(i).getTextContent());
            }
            if ("ps".equals(nodeList.item(i).getNodeName())) {
                psList.add(nodeList.item(i).getTextContent());
            }
            if ("pron".equals(nodeList.item(i).getNodeName())) {
                pronList.add(nodeList.item(i).getTextContent());
            }
            if ("pos".equals(nodeList.item(i).getNodeName())) {
                posList.add(nodeList.item(i).getTextContent());
            }
            if ("acceptation".equals(nodeList.item(i).getNodeName())) {
                acceptationList.add(nodeList.item(i).getTextContent());
            }
            Log.e("tag", nodeList.item(i).getTextContent());
        }
        hello.setPs(psList);
        hello.setPron(pronList);
        hello.setPos(posList);
        hello.setAcceptation(acceptationList);
        return hello;

    }

}

入口 ：

try {
    Hello hello=new Dom().domToxml(getResources().getAssets().open("Hello.xml"));
    Log.e("tag1",hello.toString());
} catch (ParserConfigurationException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
} catch (SAXException e) {
    e.printStackTrace();
}

将xml文件放在如下位置：

\

解析结果：

Hello{key=hello',ps=[hə'ləʊ, həˈloʊ]',pron=[
