Question
Parse text and create HTML links where appropriate
I am looking for the following stored procedure:
CREATE PROCEDURE spActivateLinks
@text varchar(8000)
AS
-- all code would go here
GO
-------------------
I simply want it to activate any potential HTML links that are contained in the text passed to it.
The following text would be parsed and converted to a link:
* External sites - "http://", "news://", "ftp://" etc etc
* Local Links - "/news" or "/news/" etc etc
-----------------
Alternatively, this can be achieved in C# but I would prefer it in SQL.
*

You can use SQL server string functions to do what you want. It is tedious and verbose compared to regular expressions, but it can be done.
Here is a sample that will create a link:
DECLARE @text varchar(4000)
SET @text = 'Turn http://www.yahoo.com into a hyperlink'
DECLARE @StartIndex smallint
DECLARE @EndIndex smallint
DECLARE @URL varchar(4000)
SET @StartIndex = charindex('http:', @text)
SET @EndIndex = charindex(' ', @text, @StartIndex)
SET @URL = substring(@text, @StartIndex, @EndIndex - @StartIndex)
SELECT STUFF(@text, @StartIndex, @EndIndex - @StartIndex, '<a href="' + @URL + '">' + @URL + '</a>')
The sample is very limited. It only handles one reference in the string. You would have to add indexes to handle multiple instances of http in the string. Also, it assumes that the reference ends with space, which may not be the case.

I noticed that Expert Exchange already do exactly what I want to:
* Notice how the "http://" and "ftp://" have been made into links.
That is EXACTLY what I want to achieve.
Cheers.
