Regular expressions that match the IMG tag and the SRC of IMG __ Regular Expressions

Text in the IMG tag:

Regular expression matching an IMG tag: string Pattern = @ "]*/s*src/s*=/s* ([']?) (? <url>/s+) '? [^>]*> ";

Regular expression that matches the src of img: string Pattern = @ "(? <=src/s*=/s*[/'/" "]?) (? <url>[http/:////]? [^'""]+)";

Get the SRC address of img in text:

String Pattern = @ "(? <=src/s*=/s*[/'/" "]?) (? <url>[http/:////]? [^'""]+)";

Regex reg = new Regex (Pattern, regexoptions.ignorecase);
MatchCollection Colmatch = Reg. Matches (text);

StringBuilder strimage = new StringBuilder ();
if (Colmatch.count > 0)
{
foreach (Match m in Colmatch)
{
Strimage.append (M.value). Append (', ');

}
}

Match the text of the IMG and add a link to the IMG tag

String Pattern = @ "]*/s*src/s*=/s* ([']?) (? <url>/s+) '? [^>]*> ";

Regex reg = new Regex (Pattern, regexoptions.ignorecase);
MatchEvaluator myevaluator=new MatchEvaluator (Repleacereg);
String content = Reg. Replace (text), myevaluator);

Repleacereg function:

private String Repleacereg (Match m)
{
String result=m.tostring ();

if (albumid! =-1)
{

           result= "<a href=ImageShow.aspx?albumid= "+ albumID +" > "+ M +" </a> ";
     }
      return result;
  }
