Let assume you have passed full html on form post to your action and you come with a need where you have to find all href link in that html string.
Assume you have got an string which contin links like
<html>
<p>
<a href="http://www.codesgonecrazy.com\">Crazy Codes </a>
</p>
<div>
<a href="http://www.othersites.com\">Other sites links</a>
</div>
</html>
To this in better way we can use regex i got in c#:
Regex regex = new Regex("href\\s*=\\s*(?:\"(?<1>[^\"]*)\"|(?<1>\\S+))", RegexOptions.IgnoreCase);
Match i;
for (i = regex.Match(textcontrolvalue); i.Success; i = i.NextMatch())
{
// Got groups of hrefs!!! ;
foreach (Group gp in i.Groups)
{
string link = gp;
}
}
Now further we can add each link in list from foreach.
enjoy!!
