Re: Retaining value of a Global variable

As in all functional languages, you can't change the value of a
variable once it is bound, so your global variable will globally have
the value of "No", that's why its called a global variable.

You mask it with a local variable but the scope of a variable binding is
its parent element which in your case is the xsl:if so it goes out of
scope at the end of that element and outside the xsl:if you will see the
global variable again.


Never use disable-output-escaping unless you are in a special non
standard case that  requires it, it is explitly non portable and not
supported by all systems. In this case it is doing nothing anyway as the
variable is just No or Yes so there is no escaping to disable.
