That's fine, though most people write match="LI/DIV" which means the same.

Technically the value of the variable is a unordered node-set, and the
filter expression $following-valid[1] selects the node in this node-set that
comes first in document order. So in effect, yes, you're OK.

But the "=" test is wrong: it compares the string-values of the nodes, not
their identity. To compare identity, use generate-id(X)=generate-id(Y), or
count(X|Y)=1. Except that in this case, I think you can simply say <xsl:if
test="$following-valid[1][self::DIV]">.
