impact on the speed of our document publishing. Some of my buddies don't
want to use xsl:for-each because they believe it causes the process to take
a longer amount of time than just doing a template match over and over. Is
this true or no? Is xsl:for-each a performance hog or does it and template
matching take the same amount of time?
I believe that's quite opposite - for-each is only about to evaluate expression and instantiate instructions within for each selected node, but using apply-templates it's also nessesary to match appropriate template, probably to up new stack frame etc. That's usually not much overhead, but it does exist and depends on the processor implementation.
Anyway that's not a reason to lose templates' virtues. Take a look at the list archive - there was a big discussion for-each vs templates this year.
