(a) The "and" operator
(b) a manual.

Oh, and (c) an understanding of the fundamentals of XML syntax

I'm sorry to pound on the poor fellow, but really, some preparatory homework is worth doing. Isn't it ironic that XML, a technology of "machine tooling" that leverages up-front effort to create huge downstream savings, is now being learned so widely by people who don't have time to make even a minimal up-front investment to help prevent time-wasting, pain and embarrassment later?

Lesson to newbies: please feel welcome to ask any (W3C) XSL question on the list. In return for this free service, please help maintain the quality of the resource by doing some preliminary research and preparation to help assure that the question you ask is a good one. A basic question to clarify the fundamental workings of the language is a good one, since it can help other newbies. A simple question about syntax that can be answered by any book or reference ... ain't.

[In XML, the '&' character is the open delimiter for an entity or character reference, so *cannot* be used alone. Since it is also not a legal name character, a document that contains '&&' is *not* XML and an XML parser must refuse to process it (the only exception being if it occurs inside a CDATA marked section). Knowing this kind of thing helps give you a sense of what's worth trying, what's not, when you're forced to guess, which really you shouldn't be.]
