If you look at $data for the problem file its not an array at that point.
For a single element XML::Simple doesn't display your data in a list i.e.
With 1 element of record.
$VAR1 = {
'RECORD' => {
'COLLNAME' => 'FBIS2004',
'DOCI' => 'CP1'
}
};
With 2 elements of record.
$VAR1 = {
'RECORD' => [
{
'COLLNAME' => 'FBIS2004',
'DOCI' => 'CP1'
},
' BOOB'
]
};
So you cant do @{$data->{RECORD}} as it doesn't exist when there is only 1
element.
You can either test that its an arrayref or hashref or you could use
something like XML::Parser, Lib:XML
Or you can tell XML::Simple that you expect the <RECORD> to be
repeated and therefore want it to be an array always. Have a look at
the forcearray option.
And if your XML starts to get too big to fit in memory have a look at
XML::Rules.
my $parser = XML::Rules->new(
rules => [
_default => 'content',
RECORD => sub {
do whatever you need with the record
the data are in $_[1]->{COLLNAME} and $_[1]->{DOCI}
return; # don't remember the data for the RECORD anymore
},
DATA => '',
]
);
$parser->parsefile('test.xml');
