Dom4j解析XML文件，处理来至XML的数据信息

XML文件
<?xml version="1.0" encoding="UTF-8"?>
<datasets name="ds1">
<locators name="LoginSetMet">
<locator name="loginLocator" by="id">login</locator>
<locator name="pwdLocator" by="name">tl_password</locator>
<locator name="submitLocator" by="xpath">//input[@name='login_submit']
</locator>
</locators>
</datasets>

使用Dom4j进行解析

package com.auto.demo1;

import java.io.InputStream;
import java.util.Iterator;

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

/** * dom4j java XML开源解析工具包 * * @author Monica * */
public class LocatorPaser {
    
    private Document doc;// 定义Document文档对象
    // 默认的构造方法中完成对XML文件的解析

    public LocatorPaser(){
        InputStream in = getInputFileAsStream(this.getClass());
        SAXReader reader = new SAXReader();//得到解析器
        try{
            doc = reader.read(in);//解析文档
        }catch(DocumentException e){
            e.printStackTrace();
        }
    }

    private InputStream getInputFileAsStream(Class<? extends LocatorPaser> testClass) {
        // TODO Auto-generated method stub
        String packageName = "";
        if(testClass.getPackage()!=null){
            packageName = testClass.getPackage().getName() + ".";
        }
        String resourceBase = (packageName + testClass.getSimpleName()).replace('.', '/');
        //得到当前类的完整路径
        String resourceName;
        ClassLoader classLoader = testClass.getClassLoader();
        resourceName = resourceBase + ".xml";
        //XML文件与当前类同名，且在同一目录下
        System.out.println("Searching for default input file:"+resourceName);
        return classLoader.getResourceAsStream(resourceName);
        //返回同名XML文件资源的获取
    }
    public String getLocator(String name){
        String locator = null;
        //查找到"datasets"标签
        Element datasets = (Element) this.doc.selectSingleNode("//datasets");
        //开始定位串解析
        for(Iterator d = datasets.elementIterator("locators");d.hasNext();){
            Element data = (Element)d.next();
            for(Iterator e = data.elementIterator("locator");e.hasNext();){
                Element elem = (Element)e.next();
                System.out.println(elem);
                //获取当前结点的值
                String value = elem.valueOf(".");
                System.out.println(value);
                //获取name属性值
                String nameString = elem.valueOf("@name");
                System.out.println("\n'"+nameString+"'");
                if(name.equalsIgnoreCase(nameString)){
                    if(!elem.valueOf("@by").isEmpty()){
                        locator = elem.valueOf("@by")+"="+value;//将by属性值与当前节点值进行拼接，如”xpath=//input[@name='login_submit']"
                    }
                    break;//完成解析，跳出循环
                }

            }
        }
        return locator;//返回定位串或者null
    }
    @Test
    public void testPaser(){
        String locator = "loginLocator";
        long curTime = System.currentTimeMillis();
        String resultString = this.getLocator(locator);
        long delta = System.currentTimeMillis()-curTime;
        System.out.println("\n"+locator+"='"+resultString+"'\nTime used(ms)::"+delta);
    }

}

运行结果：
单元测试通过！
控制台输出：
