I have this code
if (defined($xml->{account}->{p}) == '2') {
...
}
which gives me this warning
Pseudo-hashes are deprecated at a.pl line 48.
The problem is that in some cases $xml->{account}->{p} doesn’t exist, which was why I added the defined function.
$xml is an object, if that makes a difference?
How can this be fixed, so Perl doesn’t complain?
Either
$xmlor$xml->{account}is an ARRAY, not a HASH (you can userefto check this, seeperldoc -f ref). Perl had a now-deprecated feature called “pseudo-hashes” that allowed special arrays to be accessed via hash syntax. If you care about the history, you can google around for it or look at an older-edition camel book.
