Hello all,
I'm scanning millions of XML records imported from CSV looking for instances of
'bib_rec_id' which are non-numeric. Which of these two is if-statements likely
to complete earlier?
for $a in (/csv/record/bib_rec_id)
return
if ($a castable as xs:integer) then ... blah
or
if (matches($a, '^[0-9]+$')) then ... blah
Yes - I'm trying it out now, but I suspect it will be quicker to ask than wait
for either query to complete.
TIA.
