You could use xpath() to match only the selected questions:

$xpath = $xml->xpath('//main[@select="selected"]');

So you can remove the IF statement:

if($main['select'] == "selected")

Then count to get the total and create a simple pagination system:

$count = count($xpath);
$page  = isset($_GET['page']) && $_GET['page'] > 0 ? $_GET['page'] : 1;
$numbr = $page - 1;

# load the current question
$main  = $xpath[$numbr];

Once you have $main, you don't need this loop:

foreach($xml->main as $main)

Then create the page links:

<ul class="nav">
    <?php
    for($i = 1; $i <= $count; $i++)
    {
        if($page == $i)
            echo "<li><a class=\"current\" href=\"question.php?page={$i}\">{$i}</a></li>";

        else
            echo "<li><a href=\"question.php?page={$i}\">{$i}</a></li>";
    }
    ?>
</ul>

And to your form code simply add the question id, which is the attribute id in the main object:

<input type="hidden" name="questionID" value="<?php echo $main->attributes()->id; ?>" />
