I'm going to recommend that you do this a little differently.  Suggest you provide parallel construction of each of the <url> elements.  If priority is omitted, put an empty tag into the XML document.
<?php // RAY_temp_rgb192.php
error_reporting(E_ALL);
echo '<pre>';

, 'http://www.example.com/catalog?item=73&amp;desc=vacation_new_zealand'
, 'http://www.example.com/catalog?item=74&amp;desc=vacation_newfoundland'
, 'http://www.example.com/catalog?item=83&amp;desc=vacation_usa'

)
;

$xml = <<<EOD
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
EOD;

foreach ($arr as $txt)
{
    $txt = explode(',', $txt);
    $url = $txt[0];
    $pri = isset($txt[1]) ? $txt[1] : NULL;
    $xml
    .= PHP_EOL
    . '<url>' . PHP_EOL
    . '<loc>' . $url . '</loc>' . PHP_EOL
    . '<lastmod>' . date('Y-m-d') . '</lastmod>' . PHP_EOL
    ;
    if ($pri)
    {
        $xml .= '<priority>' . $pri . '</priority>' . PHP_EOL;
    }
    else
    {
        $xml .= '<priority />' . PHP_EOL;
    }
    $xml .= '</url>'
    ;

$xml .= PHP_EOL . '</urlset>';
