Hi,
I am trying to parse a xml file. Some of the tags are empty, like
this one:
# Data::Dumper output
'order_number' => {},
I have been trying to check if there is any content within the
hashref (say for order_number) returned by XML::Simple but I am not
getting the results I had hoped for.
If I do this:
if (defined($ref->{'order_number'}) && $ref->{'order_number'} =~
/\w+/ ) {
print "found $ref->{'order_number'}\n";
}
I get "found HASH(0xacacfe8)".
Using 'defined' gives me the same results. What is the correct way to
check for content/values within a hashref? Is a element always
defined if it is within the XML even if it has no values? Should I
scalar it first?
Thanx in advance,
Dp.
