我对 HTML 解析/抓取的整个想法比较陌生。我希望我能来这里得到我需要的帮助!
基本上我想要做的(我认为)是指定我希望从中获取数据的页面的 url。在这种情况下 - http://www.epgpweb.com/guild/us/Caelestrasz/Crimson/
从那里，我想在 div id=snapshot_table 中获取表 class=listing。
然后我希望将该表嵌入到我自己的页面上，并在原始内容更新时更新它。
我已经阅读了 Google 和 Stackoverflow 上的一些其他帖子，我还查看了 Nettuts+ 上的教程，但它似乎有点太多了，无法一次接受。
希望这里有人能帮助我，让这个尽可能简单:)
干杯，
