$node->taxonomy

Hello,

I am building a website from a huge amount of files that are generated from a shell script, I have found a way to insert the generated HTML pages into drupal by using the following code:

<?
function mySave($type, $title, $body) 
{

     $edit = array();
                $edit['type'] = $type;
                // get the node type defaults
                $edit['uid'] = 1;
                $edit['name'] = 'mathQuestion';
                $edit['promote'] = 0;
                $edit['comment'] = 0;
                //$edit['revision'] = ;
                $edit['format'] = FILTER_HTML_ESCAPE;
                $edit['status'] = 1;

                $edit['title'] = $title;
                $edit['body'] = $body;

                $edit['date'] = format_date(time(), 'custom', 'Y-m-d H:i:s O');

                node_invoke_nodeapi($edit, $type);

                node_validate($edit);
                if ($errors = form_get_errors()) {
                    print_r($errors);
                }

                $node = node_submit($edit);
                node_save($node);
}


include_once './includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);

if($_SERVER['argc'] != 4) 
{
	echo "Expected 3 arguments: FileName,Question,PageNumber\n";
	die();
}
$arg=$_SERVER['argv'];
$title=$arg[2] . $arg[3];

$myFile=$arg[1];
$fh = fopen($myFile, 'r');
if($fh==FALSE) 
{
echo "Unable To Open File $myFile"; 
die();
}
$size=filesize($myFile);
$content = fread($fh, $size);
fclose($fh);


mySave('mathsln',$title,$content);

?>

What I am unable to figure out is how to group my new nodes using taxonomies. How to create those Taxonomies through code would be great too, but I can do that manually.

Thanks in advance,
Afief
