php xml pagination issues missing one result

the following code i set to have results from xml put into pagination, it is working for the most part, but it is missing a line each time.

so i have it set at 7 it only shows 6 results per page here is my Code:

$thispage= $_SERVER['PHP_SELF'];
$startPage = $_GET['page'];
$perPage =7;
$currentRecord = 0;

/  Start XML Parsing
    $dom = new DOMDocument();
    $dom->load('Playlist.xml');

    $xmlPath = new DOMXPath($dom);
    $arrNodes = $xmlPath->query('//channels/channel');

         foreach($arrNodes as $item){

         $currentRecord += 1;
         if($currentRecord > ($startPage * $perPage) && $currentRecord < ($startPage * $perPage + $perPage)){

       // Get Name
        $id=$item->getAttribute('id');

        // lets limit title
        $string=$item->getAttribute('name');
        $finTitle = (strlen($string) > 55) ? substr($string,0,52).'...' : $string;

        // lets limit  category
        $cat=$item->getAttribute('category'); 
        $category= (strlen($cat) > 20) ? substr($cat,0,17).'...' : $cat;
        // now we have the URL to pass on
        $vidUrl=$item->getAttribute('url'); 

    if($bgcolor=='#f1f1f1'){$bgcolor='#ffffff';}
    else{$bgcolor='#f1f1f1';}

    echo "<tr >";
    echo "<td bgcolor=$bgcolor id='title ' align=center>&nbsp;<font face='Verdana' size='2'>$id</font></td>"; 
    echo "<td bgcolor=$bgcolor id='title' align=center>&nbsp;<font face='Verdana' size='2'>$finTitle</font></td>";
    echo "<td bgcolor=$bgcolor id='title' align=center>&nbsp;<font face='Verdana' size='2'>$category</a></font></td>";
    echo "</tr>";
    }
}

Thanks i am sure i am just missing something somewhere at first i thought it was here : $currentRecord += 1; but if i change that to just 1 or 0 it will not show any results
