像什么Digg的那样，当你提交一则新闻，标题和摘要的自动检索，该怎么办呢？
Like what digg does,when you submit a news,the title and summary is automatically retrieved,how to do it?
推荐答案
检索HTML并解析它。
Retrieve the HTML and parse it.
标题来自于＆LT;冠军＆GT; 标记。
摘要可以来自：
The title comes from the <title> tag.
The summary can come from either:
＆LT;身体GT; 标记
的说明＆LT;元＆GT; 标记
The first couple of hundred characters of visible text from inside the <body> tag.
The description <meta> tag.
如果网站提供的RSS源（你会发现在＆LT;链接相对=交替式=申请/ RSS + XML＆GT; 从替代标签）使用的列装的信息。
If the site provides an RSS feed (which you'll find in the <link rel="alternate" type="application/rss+xml"> tag) use the fielded information from that instead.
有没有一个正确的回答了这个问题。可能有其他可能的策略。但是，这应该让你开始。
There is no one right answer to this question. There are probably other strategies possible. But this should get you started.
