I often do:
<xsl:if test="position() mod 1000 eq 0">
<xsl:message select="concat('Processed ', position(), '/', $total')"/>
to output:
Processed 1000/1000000
Processed 2000/1000000
...
which is good enough to show something is happening but it would've
been nicer to also show an estimated finish time based on progress so
far.
Maybe a little off-topic Perl wrapper will do for you, which allows you
to keep XSL pure while at the same time notifying you when you may get
back to your long-running XSL task:
mludwig(_at_)forelle:~/Werkstatt/xsl > cat timer.pl
use strict;
use warnings;
use Time::HiRes 'time';
my $t0 = time;
while (<>) {
chomp;
my($processed, $total) = m#(\d+)/(\d+)#g;
if (! ($processed and $total) or $processed > $total) {
warn "problem understanding '$_'\n"; next;
}
my $percent = 100.0 * $processed / $total;
my $time_used = time - $t0;
my $time_per_item = $time_used / $processed || 1;
if ($processed == $total) {
printf "Processed %u/%u in %.2f s, %.5f s per item\n",
$processed, $total, $time_used, $time_per_item;
last;
}
my $timeleft = $time_per_item * ($total - $processed);
printf "Processed %u/%u in %.2f s, %.2f%%, %.2f s estimated till
end\n",
$processed, $total, $time_used, $percent, $timeleft;
}
