我有这个正则表达式，可以在我的文本字符串中找到 HTML 锚标记之间的文本。文本类似于推文，因此示例字符串为：

   http://google.com is great, but http://www.stackoverflow.com may be my only hope. www.yahoo.com is out of the question.

它贯穿我的工作正则表达式：

function processTweetLinks(text) {
       console.log(text);
           text = text.replace();

   var replacedText, replacePattern1, replacePattern2;

   //URLs starting with http://, https://, or ftp://
   replacePattern1 = /(\b(https?|ftp):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/gim;
   text = text.replace(replacePattern1, '<a class="individualMessageBioWhateverLink" href="$1" target="_blank">$1</a>');

   //URLs starting with "www." (without // before it, or it'd re-link the ones done above).
   replacePattern2 = /(^|[^\/])(www\.[\S]+(\b|$))/gim;
   text = text.replace(replacePattern2, '$1<a class="individualMessageBioWhateverLink" href="http://$2" target="_blank">$2</a>');

   console.log(text);
   return text;
   }

结果如下：

  <a class="individualMessageBioWhateverLink" href="http://google.com" target="_blank">http://google.com</a> is great, but <a class="individualMessageBioWhateverLink" href="http://www.stackoverflow.com" target="_blank">http://www.stackoverflow.com</a> may be my only hope. <a class="individualMessageBioWhateverLink" href="http://www.yahoo.com" target="_blank">www.yahoo.com</a> is out of the question.

我想要另一行或两行来抓取<a></a>标签之间的内容，找到链接的开头（例如，, , http://. , ），然后删除它们，留下仍然可以识别为用户链接的最短可能文本（“ ”）。我有一个正则表达式，它似乎可以正确筛选文本并在标签之间而不是在 href 中找到这些东西。这是表达式：https://http://wwwhttps://www.google.com<a></a>

   (?:<a [^>]+>.*?)(([a-zA-Z]{3,5}\:\/\/){0,1}(www\.))(?:.*?<\/a>)

`http://` and `https://` are in `$2`, and `www.` is in `$3`. How would I use this in the context of my function?

使用 dom 解析使其变得简单。如果您想从中删除http://等，您可以应用任何正则表达式

$('a').each(function(){
  alert(this.href);
});
