PROFESSIONAL VISUAL BASIC 6 XML PART 4 - VARIABLES AND PARAMETERS
Once you have read this section, you will have found out that its title is a bit deceptive. You, as a programmer, have certain expectations about a new programming language when you start learning it. One of them is that you expect it to be possible to store values in variables, change them and retrieve them later. Although XSLT has an element called variable, you actually cannot do much with it. This may sound unbelievable, but it is a result of the way XSLT works that you cannot have variables. This is a thing that beginning XSLT programmers have many difficulties grasping.
