Question

The following regular expression works if there is no space character, but if the input has a space character, it doesn’t work (it seems like a link but JavaScript doesn’t work).

How can I change it?

The regular expression should work for both World and The World.

    Dim makebkz As String     Dim pattern As String = '\(bkz: ([a-z0-9$&.öışçğü\s]+)\)'     Dim regex As New Regex(pattern, RegexOptions.IgnoreCase)     Dim myAnchor As New System.Web.UI.HtmlControls.HtmlAnchor()     Dim postbackRef As String = Page.GetPostBackEventReference(myAnchor, '$1')     myAnchor.HRef = postbackRef      str = regex.Replace(str, '(bkz: <a href=javascript:' & myAnchor.HRef & '><font color=''#CC0000''>$1</font></a> )')     makebkz = str     Return makebkz

I think this line should be changed:

str = regex.Replace(str, '(bkz: <a href=javascript:' & myAnchor.HRef & '><font color=''#CC0000''>$1</font></a> )') 

If I read your code correctly you are including the $1 in the HRef (that’s what the Page.GetPostBackEventReference(myAnchor, ‘$1’) is doing), and then replacing it in both the text between the font tags and the href, so your output would be something like:

(bkz: <a href=javascript:__doPostBack(The World)><font color=''#CC0000''>The World</font></a> ) 

If you update your replace function to this, it should work:

str = regex.Replace(str, '(bkz: <a href=''javascript:' & myAnchor.HRef & '''><font color=''#CC0000''>$1</font></a> )') 

I.e. wrap the javascript call in quotes, and your world will be good.
