Re: multidimensional insertion order

Alright, let's try again.

I'm parsing a quasi-xml file into a hash, and here is the code that is relevant:

# keep hashes in order of entry
tie %xml_lines, "Tie::IxHash";

# Open XML file
open (XML, "/samples/radiology2") || die("Can't open XML File: $!.");

$section_number = 1;
# Read XML file into a hash
while (<XML>) {
	trim($_);
	if (/^<(.+?)>(.+?)<\/\1>$/) {
		$contents = trim($2);
		$contents =~ s/\|/<br>/g;
		$contents =~ s/<br> /<br>/g;
		$contents =~ s/ <br>/<br>/g;
		tie $xml_lines{$section}->{$section_number}, "Tie::IxHash";
		$xml_lines{$section}->{$section_number}->{$code_name} = $contents;
}
etc

The first tie (tie %xml_lines, "Tie::IxHash";) maintains insertion order at the {$section_number} level.

The second tie (in the if statement) is where I get the error "Can't locate object method "TIESCALAR" via package "Tie::IxHash" at wis_xml_to_html.pl line 56, <XML> line 2."

How do I use Tie::IxHash to maintain the order of insertion in my while loop at the {$code_name} level?

Apologies to the offended,
