when applying templates it is possible to filter out unwanted nodes in a
number of ways, one is by putting a predicate on the apply-templates command
and use modes if you have more than one filter. Another is to
apply-templates to all nodes and put a predicate on the template match -
this avoids the use of modes.
I can see 3 advantages for doing the former:
It improves efficiency i.e. the processor will only begin searching for
relevant elements rather than searching for matches which are then filtered
improves the readability of the stylesheet. The author will know
definitively which template is being invoked without having to look through
imported and included stylesheets.
In a situation of no suitable match being found the inbuilt <xsl:template
match="*"> template will be invoked if it hasnt been overridden which could
lead to either unexpected or unnecessary searching.
Can anyone provide any more or provide advantages of doing the latter?
