No. XSLT template rules follow an event-based processing model. A template
rule says "if X is encountered, do this". The order of processing is
determined by the order of events, not the textual order of the rules.

There's one exception: if you have two template rules that match the same
"event" (i.e. the same node in the source document), it's technically an
error, but the processor can resolve the ambiguity by choosing the rule that
comes last in the stylesheet.

Nothing done by a stylesheet ever affects the source tree. Templates write
new nodes to the result tree, without changing the source tree.
