No, the JSTL 1.0 EL doesn't support any facility for substring matches. It's often best to use another custom tag library, or Java code in a servlet, for that. In JSP 2.0, the proposed support for "functions" will let you register a function to do substring matching and other common string operations. -- Shawn Bayern "JSTL in Action" http://www.jstlbook.com (coming in July 2002 from Manning Publications) -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
