I use the following code to make links clickable where the link begins with www.<br />

<pre><code id="code-10-27651053-1">input = RegularExpressions.Regex.Replace(input, &quot;(\www\.\S+[^\s@,.&quot;&quot;']+)&quot;, &quot;&lt;a href=&quot;&quot;http://$1&quot;&quot;&gt;$1&lt;/a&gt;&quot;)</code></pre>
<br />
The problem is that this becomes clickable links:<br />
z<a href="http://www.example.com" rel="ugc">www.example.com</a><br />
/<a href="http://www.example.com" rel="ugc">www.example.com</a><br />
&gt;<a href="http://www.example.com" rel="ugc">www.example.com</a><br />
<br />
It should ONLY become a clickable link if it starts with www and does not have another charactor (other than whitespace)

It should ONLY become a clickable link if it starts with www and does not have another charactor (other than whitespace)

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,
