Every time an <xsl:template/> that contains an <xsl:variable/> element is executed, that <xsl:variable/> element will be reinitialized. However, XSLT can never change the value of the variable once it is created; it can only let it go out of scope and restart. > > 2.

You could output a node for every time the template is executed, but that may not be what you're looking for. > 3. Is there an easy to implement a counter or a boolean in > xsl? If yes then how? Implementing either one would be fine. > I can't think of any convenient ways, except to point out that the boolean() function and the idea of boolean values already exists in XSL. So does the concept of a counter; see the position() and number() functions. But if you're trying to keep a running total and use that in other areas like a traditional variable in a functional language, I'm not sure how you'd do it. Possibly someone who knows more than I do can help there. Regards, Corey M.
