最近 @甜瓜 (QQ:1069629945) 开发了一套NBA数据采集脚本, 我觉得很赞. 经他允许发布出来和大家分享一些经验:

球员球队: http://data.sports.sohu.com/nba/nba_team_info.php?teamid=1 .. 30

在1到30的循环中抓取球队信息, 球员信息并用id将其关联起来, 脚本如下:

public void Run()
{
    Logger.ClearAll();
    for(int i=1; i<=30; i++)
    {
        Default.Navigate("http://data.sports.sohu.com/nba/nba_team_info.php?teamid="+i);
        Default.Ready();
        var teamid = i;
        var teamname = Default.SelectSingleNode("div.blockA>h2>span");
        Logger.Log(teamname.Text());
        var teamurl = Default.SelectSingleNode("div.blockB>div.left>div.pt>ul>li>a");
        Logger.Log(teamurl.Text());
        var teamcity = Default.SelectSingleNode("div.blockB>div.left>div.pt>ul>li:eq(1)");
        Logger.Log(teamcity.Text().Replace("主场所在城市：",""));
        var gym = Default.SelectSingleNode("div.blockB>div.left>div.pt>ul>li:eq(2)");
        Logger.Log(gym.Text().Replace("主体育馆：",""));
        var peoplenum = Default.SelectSingleNode("div.blockB>div.left>div.pt>ul>li:eq(3)");
        Logger.Log(peoplenum.Text().Replace("可容纳人数：",""));
        var intonba = Default.SelectSingleNode("div.blockB>div.left>div.pt>ul>li:eq(4)");
        Logger.Log(intonba.Text().Replace("加入NBA时间：",""));
        var champion = Default.SelectSingleNode("div.blockB>div.left>div.pt>ul>li:eq(5)");
        Logger.Log(champion.Text().Replace("获总冠军次数：",""));
        var coach = Default.SelectSingleNode("div.blockB>div.left>div.pt>ul>li:eq(6)");
        Logger.Log(coach.Text().Replace("现任主教练：",""));
        DataManager.AppendData("TEAM",
                               DataEntry.Create()
                               .Set("teamid", teamid+"")
                               .Set("teamname", teamname.Text())
                               .Set("teamurl", teamurl.Text().Replace("主场所在城市：",""))
                               .Set("gym",gym.Text().Replace("主体育馆：",""))

                               .Set("coach", coach.Text().Replace("现任主教练：",""))
                              );

                               .Set("jiashiscore3",jiashihomescores3)
                               .Set("jiashiscore4",jiashihomescores4)
                              );


    }

}

这里的亮点是要看48, 49两行, 这里对加时赛也进行了处理. 不是所有的比赛都有加时赛, 就算有也可以打多场(1-4场). 因此甜瓜非常细心的对这块也做了处理. 个人感觉这块代码也还是有优化的余地, 但是这种处理也非常简单直白, 一目了然, 也是很不错的. 

最后运行起来:
