Thanks for the speedy response.

apply-templates select=X
template match=X[condition]
template match=X[not(condition)]
[/quote]
That makes perfect sense, except i'm not too sure how to apply a condition
that way. I'm only aware of xsl:choose, xsl:when and xsl:otherwise logic.
How can a condition be applied in a template match?

Instead of writing
if (condition)
apply-templates select=X mode=A
else
apply-templates select=X mode=B
template match=X mode=A
template match=X mode=B
write instead:
apply-templates select=X
template match=X[condition]
template match=X[not(condition)]
That is: let the template rules do the work.
You haven't shown your source document but it seems a little odd. Usually
documents with a ROWSET and ROW are rather flat, they tend only to have one
level of element below the ROW. You appear to have
TEAM/TEAM_ROW/NAME/NAME_ROW/SALARY
within each ROW. Can each of these elements only appear once in each row?
If
so, why all the nesting? But if not, your stylesheet logic looks wrong,
because the apply-templates processes all the elements in the set, while
the
when condition tests if ANY element satisfies the condition. (But it's
possible this is what you intended, who knows?)
