The good news is that you most likely won't have to have "loops running through
seperate nodes" (an elementary school teacher once told me to remember that
there is "a rat" in separate).
The bad news is that your message isn't clear in regard to what you want. If
what you want is to revisit a node or set of nodes in your XML document more
than once with different output on each visit, investigate the "mode" attribute
on <xsl:template> and <xsl:apply-templates>.
"invariables" actually make things simpler in that they eliminate a group of
potential bugs caused by "side effects". All you have to do is un-learn loops
and learn apply-templates instead.
Give us a chance to help by being clear in what you need.
