Me again with the noob question.
I want to achieve this:
At the url http://ROOT/something/{numeric_id_here} to get a page that lists the header and the footer of the theme and my custom content. The content is not manage-able through the admin. It depends on the numeric id.
Here is what I got so far.
I use the hook_menu for this:

function something_menu() {
    $items['something/%id_here'] = array(
        'title' => 'Some title',
        'type' => MENU_NORMAL_ITEM,
    );
    return $items;
}

I have the function that parses the url and gets the numerical value:

function id_here_load($arg) {
    $data = get my custom data from an external xml feed based on $arg; //this works nicelly - I get an array with the data I need.
    //WHAT'S NEXT?
}

Now I'm stuck. how can I pass $data to a template and render that template in the content of the page?
My question is somehow similar to this one. Just that the answers provided there don't cut it for me.
