使用watij和xpath实现自动spider(完善中)

watij本来是用于web测试的，但是我发现利用它来做垂直爬虫，效果也很好
以下的代码抓了三个网站

package com.example.tests;

import watij.runtime.ie.IE;
import watij.finders.AttributeFinder;
import watij.finders.Finder;
import watij.finders.NameFinder;
import watij.finders.XPathFinder;
import watij.finders.FinderFactory.*;
import watij.elements.*;


public class WatijHotel {
