VB.Net Regular Expression
I'm working on a function that will take a block of text and convert any urls into hyperlinks. I confess to not knowing much at all about regular expressions. At any rate, what I have so far is working (
 ). Unfortunately, it's working for everything. Anything you pass to it will become a URL, even text. How can I write this expression better?Code:
Imports System.Text.RegularExpressions
Imports System.Uri
Function MakeLink(ByVal sURL)
Dim reString As String = "(?<url>[(http|ftp|https):\/\/]?[\w]+(.[\w]+)([\w\-\.,@?^=%&:/~\+#]*[\w\-\@?^=%&/~\+#])?)"
sOutput = Regex.Replace(sURL, reString, "<a href=""${url}"" target=""_blank"">${url}</a>", RegexOptions.IgnoreCase)
MakeLink = sOutput
End Function

Not good with regular expressions at all, but my luck is that there are scripts allready made:

Thank you very much, EiSa! A little tweaking and this worked out perfectly for me...
