Regex.Replace not working as required.

[user1980]

Hi there,



I am trying to replace text in my xsl file. I have to replace all the http and https. But I can leave any links that start with <a href>

Ie; http://www.google.com has to replaced. But < a href=”google.co m”>google.com</a> has to remain as it is.



I am using regex to find all the http(s) and a hrefs in the text. I am struck here.

My code is,

Dim href As New Regex("(<a.*?>.*?</a>)", RegexOptions.IgnoreCase)

Dim hrefs As New Regex("http(s)?://([\w+?\.\w+])+([a-zA-Z0-9\~\!\@\#\$\%\^\&amp;\*\(\)_\-\=\+\\\/\?\.\:\;\'\,]*)?", RegexOptions.IgnoreCase)

    
        Dim matchahref As MatchCollection = href.Matches(StrIn)

        Dim matches As MatchCollection = hrefs.Matches(StrIn)

 
for each match in matches
StrIn = Regex.Replace(StrIn, "(http|ftp|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,@?^=%&amp;:/~\+#]*[\w\-\@?^=%&amp;/~\+#])", _

                                      String.Format("<a href=""{0}"">{0}</a>", match.ToString()))
next

I am trying to use Regex.Replace to replace my https. But I am unable to write the evaluate function.

My regex.replace replaces all the values with a single value.



Can some on please correct my regex.repalce. thank you.
