I expected a record that looked like this:

but instead got a record that looked like this:

(some of the non-printable characters have been replaced with newlines for readability.)

After staring at that record for entirely too long, forgetting about it for a while, then returning again to think about how unreadable it was, then forgetting about it again, then taking one last look, I had that *duh* moment that made me realize what I should have seen on first glance: this is a MARC record that hasn’t had its directory parsed.

So here’s my short-but-handy-and-hopefully-usefull-to-somebody-sometime code to parse the directory and then the rest of the record. It assumes $records is an array of records.

foreach($records as $record){
	$temp = explode('', $record);
	$dir = $temp[0];
	$record = substr($record, (strlen($dir) + 1));

	$dir = substr($dir, 24);
	$dir_field = NULL;
	while($dir){
		$dir_field[] = substr($dir, 0, 12);
		$dir = substr($dir, 12);
	}

	$record = str_replace('', '|', $record);
	$marc = NULL;
	foreach($dir_field as $field){
		if(ereg_replace('[^0-9]', '', $field)){
			unset($temp);
			$len = substr($field, 3, 4);
			$pos = substr($field, 7, 5);
			$field = substr($field, 0, 3);
			$temp = substr($record, $pos, $len);
			if($field < 10)
				$temp = '  |'. $temp;
			$marc .= trim($field .'|'. $temp) .“\n”;
			$marc_array[$field] = $temp;
		}
	}
	echo $marc;
}

The actual output of that code on that record is this:

It includes a little bit of fudging that my other MARC parsing code demands, but works and is readable.
