Hey Folks, A quick question if you will... I'm parsing an XML Document into a perl data structure using XML::Simple with the default (Read: No) options. I'm trying to do something with each of the "Map" elements that get parsed out of the XML but i'm not iterating correctly over the structure. Here's my code
my $refdata = XMLin('C:/myxmltest.xml'); print ref($refdata) . "\n"; # Prints out HASH print ref($refdata->{'Map'}) ."\n"; # Prints out ARRAY print ref($refdata->{'Map'}[0]) . "\n"; # Prints out HASH # But when I try ... foreach my $href ( $refdata->{'Map'} ){ print $href->{'MapId'} ."\n"; }
I get a Argument "VC3NEDX$" isn't numeric in hash element at E:\code\xmltest2.pl line 23. Bad index while coercing array into hash at E:\code\xmltest2.pl line 23. Although 'VC3NEDX$' is exactly what i want to print out and is indeed available in $refdata->{'Map'}[0]->{'MapId'} Me thinks i need a little Smack, Up-side the head. Thanks, Dan.
