原始文本上的正则表达式链接匹配 [英] Regex link matching on raw text

问题描述

任何人都有任何想法如何匹配此类字符串中的链接：

   http://www.youtube.com/Vid56xtghhttp://vimeo.com/channel/id=14498http://rapigator.net/file/345gtrG/mike_goes_mad.avi 

基本上这个字符串包含3个合并在一起的链接。我需要以某种方式将它分成3个不同的链接。用正则表达式做任何事情都可以吗？



谢谢！



我尝试过什么：



尝试使用正则表达式，但没有运气。不确定如何在另一个http（s）？：//（www \。）？时停止它？到达块...

解决方案

你可以试试这个

 http :(？:(？ ！http：）。）* 

它将匹配从http：到下一次出现，但不包括它。

结果你的样本字符串将是3个单独的匹配。



[更新]

忘记https变种：

< pre lang =text> http（？：s）？:(？:( ?! http（？：s）？：）。）*

我想您必须阅读正则表达式文档以了解高级用法。

到底是怎么回事，你是怎么以单个字符串中的3个链接那样愚蠢的结局？

Anyone got any ideas how to match links from such string:

"http://www.youtube.com/Vid56xtghhttp://vimeo.com/channel/id=14498http://rapigator.net/file/345gtrG/mike_goes_mad.avi"

Basically this string contains 3 links merged together. I need to separate it out somehow into 3 distinct links. Any way to do that with regular expression?

Thanks!

What I have tried:

Tried playing with regular expressions but without any luck. Not sure how to stop it when another "http(s)?://(www\.)?" block is reached...

解决方案

You can try this

http:(?:(?!http:).)*

It will match from http: up to the next occurence, but not including it.
The result of your sample string will be 3 separate matches.

[UPDATE]
Forgot the https variant:

http(?:s)?:(?:(?!http(?:s)?:).)*

See solution 1 for a working solution.

I guess you will have to read regex documentation to understand advanced usages.

By the hell, how did you end with something as stupid as the 3 links in a single string ?
