John Gruber刚刚发布了一个有趣的正则表达式示例来捕获URL:

为了切入正题,他选择了(自由的、长期的)模式:

<a href="http://stackoverflow.com">http://stackoverflow.com</a>
\b(([\w-]+:/?(www[.])[^\s()]+(?:\([\w\d]+\)|([^[:punct:][\s]./))
这假定要捕获以下所有内容:

\b(([\w-]+://?|www[.])[^\s()<>]+(?:\([\w\d]+\)|([^[:punct:]\s]|/)))

只是一个www.example.com链接。
因此,您将使用类似的模式,然后以某种方式迭代返回的匹配数组。我想是吧。我讨厌正则表达式
