Implementation of regular expression extraction URL, title, image, etc. (.Net Asp Javascript/Js)

In some cases of crawling, filtering, etc., the advantages of regular expression regular expression are very obvious.
For example, there is a string like this:

Copy the codeThe code is as follows:

<li><a href="/something/article/" title="FCKEditor highlight code plug-in test"><span class="article-date">[09/11]</span>FCKEditor highlight code plug-in test</a></li>

Now, you need to extract the URL after href, the date in [], and the text of the link.
The following is the implementation method of C#, ASP and Javascript
Implementation of C#

Copy the codeThe code is as follows:

string strHTML = "<li><a \"href=/something/article/\" title=\"FCKEditor highlight code plug-in test\"><span class=\"article-date\">[09/11]</span>FCKEditor highlight code plug-in test</a></li>";
string pattern = "http://([^\\s]+)\".+?span.+?\\[(.+?)\\].+?>(.+?)<"; 
Regex reg = new Regex( pattern,  ); 
MatchCollection mc = ( strHTML ); 
if ( > 0) 
{ 
foreach (Match m in mc) 
{ 
( [1].Value ); 
( [2].Value ); 
( [3].Value ); 
} 
} 

Implementation of ASP

Copy the codeThe code is as follows:

<% 
Dim str, reg, objMatches 
str = "<li><a href=""http://localhost/Z-Blog18/article/"" title=""FCKEditor highlight code plug-in test""><span class=""article-date"">[09/11]</span>FCKEditor highlight code plug-in test</a></li>"
Set reg = new RegExp 
 = True 
 = True 
 = "http://([^\s]+)"".+?span.+?\[(.+?)\].+?>(.+?)<" 
Set objMatches = (str) 
If  > 0 Then 
("Website:")
(objMatches(0).SubMatches(0)) 
("<br>") 
("date:")
(objMatches(0).SubMatches(1)) 
("<br>") 
("title:")
(objMatches(0).SubMatches(2)) 
End If 
%> 

Javascript implementation

Copy the codeThe code is as follows:

<script type="text/javascript"> 
var str = '<li><a href="http://localhost/Z-Blog18/article/" title="FCKEditor highlight code plug-in test"><span class="article-date">[09/11]</span>FCKEditor highlight code plug-in test</a></li>';
var pattern = /http:\/\/([^\s]+)".+?span.+?\[(.+?)\].+?>(.+?)</gi; 
var mts = (str); 
if (mts != null) 
{ 
alert(mts[1]); 
alert(mts[2]); 
alert(mts[3]); 
alert(mts[4]); 
} 
</script>
