Jamie has included some great suggestions. All of which I recommend over this one, but most people don't realize that there is limited string manipiulation possible using JScript functions (i.e. substring and indexOf) within DWT TBBs. So this is possible:

@@"[email protected]".substring(0,("[email protected]").indexOf("@"))@@<br/>
@@"[email protected]".substring(("[email protected]").indexOf("@"))@@

Of course you can use a field value instead of the whole string, but this shows the point. I think this is pretty ugly, and would really suggest creating a Function Source, but in a pinch, this would work for you.

  • thank you, i can get this to work as detailed using a string

Depending on what the use case is, there are several approaches, for example, do you want to apply this behaviour to all the email addresses in the output? is it in a specific situation?

If it is the first case (apply to all email addresses) you can achieve that by implementing a C# TBB that "finds" all the email addresses (with a regular expression for example) and replace them with the "splitted" version of them.

If it is for a specific "field", you could pass the field name as a parameter using a parameter schema in the very same TBB and only replace the email address that matches the field you passed by as a parameter.

Yet another option would be to implement a Dreamweaver Function something like 'SplitEmailAddress(email)' that will do the job for you. Then you should be able to do something like @@SplitEmailAddress(${Component.Fields.email})@@.

However you need to take into account what is a "new line" for you. It could be a \n or \r or a html 'br' element, etc...

  • <%@ Import Namespace="System.Collections.Generic" %> <%@ Import Namespace="System.Linq" %> <%@ Import Namespace="System.Text.RegularExpressions" %> /// Fragment Functions <%! private string getEmailLeft(string strValue) { string strEmailLeft =""; strEmailLeft = strValue.Substring(0, strValue.LastIndexOf("@")); return strEmailLeft; } %>

  • To create a custom function, you'll need to create an assembly with a class implementing the IFunctionSource interface and method(s) with the TemplateCallable attribute. There's information about the general approach here: sdllivecontent.sdl.com/LiveContent/content/en-US/… and you should be able to find the details in the API documentation for the above mentioned classes.
