Regex to extract URL subdirectories.

Ok, let me tell you what I've got so far :

                  string myPath = "http://www.myexample.com/subdir1/subdir2/subdir3/";

                  string mapTo = myPath;
                  Regex regMap = new Regex(@"\/[a-zA-Z0-9]+\/",RegexOptions.IgnoreCase);
                  
                  foreach( Match matchExpr in regMap.Matches(mapTo) )
                  {
                        string expr = matchExpr.ToString();
                        Console.WriteLine('>'+expr);
                  }

This is outputing "subdir1" and "subdir3", somehow it skips "subdir2" !!
Why ?

and you don't have escape '/' char,                  
Regex myRegex = new Regex( "/[a-zA-Z0-9]+/",RegexOptions.IgnoreCase );

will do just fine

(but won't solve your problem) :(

try this:

Regex myRegex = new Regex( "/[a-zA-Z0-9][a-zA-Z0-9]+",RegexOptions.IgnoreCase );

it'll get all subdirs but it will get "www" as well but you can easily parse it later or think how to modify your regex to avoid it.

regards

Slight modification to skip //www:

"/[^/a-zA-Z0-9][a-zA-Z0-9]+"

hmm, for some reason

"/[^/a-zA-Z0-9][a-zA-Z0-9]+"

doesn't work for me - it doesn't find anything in the string (http://...) above.

isn't it a contradiction? we want it to have the first character '/' but not to start with '/'...

regards

this one works fine, should i accept the answer? ;)

I would if I were you :))  Actually, I'll split with you ;)
