You don't believe in anachy and accidental development via evolution?:-)
You mean its not true? ;-)
number() forces coersion to numbers at places where it wouldn't happen
automatically. Notably
foo[(_at_)bar]
takes foo elements that have a bar attribute
foo[number(@bar)] takes the foo element whose position() is equal to
the numeric value of its bar attribute.
Aaaahhhhh.... Ok, that now makes perfect sense.
test="@foo=1"
is false if the source has foo="1.0"
but
test="number(@foo)=1"
would be true in that case.
again, this brings in to light the purpose of the function... I have a
lot of code that needs some clean up to due to implementing a completey
pointless function call... Won't bother timing the savings of time
during the transformation as I doubt it will be much but having a better
understanding of the number() function definitely will help me with a
few things here and there that I have struggled with in the past (the
dynamic position assignment in particular in most useful!!! Thanks
David! :)
Cheers!
