( #3333=superdoc: print w/replies, xml ) Need Help??

The bottom loop should be

for (@$sales_inserts) { my $table = shift(@$_); my $sth = $dbh->prepare(' INSERT INTO '.$dbh->quote_identifier($table).' ( ItemID, Day, Revenue, Count ) VALUES ( ?, ?, ?, ? ) '); $sth->execute(@$_); }
or
my %sth_cache; for (@$sales_inserts) { my $table = shift(@$_); my $sth = $sth_cache{$table} ||= $dbh->prepare(' INSERT INTO '.$dbh->quote_identifier($table).' ( ItemID, Day, Revenue, Count ) VALUES ( ?, ?, ?, ? ) '); $sth->execute(@$_); }

    [ambrus]: Corion: as for that, I talked with schmorp, and looked a bit more at Prima
    [ambrus]: Corion: from the docs, it definitely looks like it would be possible to write an AnyEvent driver for it using Prima::File and Prima::Timer.
    [ambrus]: (I haven't found an idle event.)
    [ambrus]: However, I also looked at the internals, and found two interesting things:
    [marto]: stupid xpath question, I have a xpath copied from the browser, is the * wildcard supposed to work for IDs? e.g. '//*[@id="*"]/ div/div/header/p/a '?
    [ambrus]: The main loop for unixish systems is in https://metacpan. org/source/ KARASIK/Prima-1. 49/unix/apc_app.c. It is a hand-rolled select loop, but also always spins at least once every 0.2 seconds for some reason.
    [ambrus]: marto: no, not that way. if you just want to test for an existing id attribute, then write *[@id] , or you can match a regexp to the value of that attribute like *[@id=~/something/ ]
    [marto]: ambrus, thanks I ended up going with '//*[starts- with(@id, "thread_")]...
