使用您提供给我们的字符串，您可以执行此操作。

$str = "<Countries><Country><Code>AF</Code><Name>Afghanistan</Name></Coun‌try><Country><Code>AL</Code><Name>Albania</Name></Country><Country><Code>DZ</Code‌> <Name>Algeria</Name></Country><Country><Code>AS</Code><Name>American Samoa</Name></Country></Countries>";
$str = substr_delimeters($str, "<Countries>", "</Countries>");
$countries = explode("</Country>", $str);
echo "<select name='countries'>";
foreach($countries as $country)
{           
    if($country != '')
    {
        $country_name = substr_delimeters($country, "<Name>", "</Name>");
        $country_abrev = substr_delimeters($country, "<Code>", "</Code>");        
        echo "<option value='" . $country_abrev . "'>" . $country_name . "</option>";
    }
}    
echo "</select>";
function substr_delimeters($inputstr,$delimeterLeft,$delimeterRight) {
    if (empty($inputstr) || empty($delimeterLeft) || empty($delimeterRight)) return false;
    $posLeft  = stripos($inputstr,$delimeterLeft)+strlen($delimeterLeft);
    $posRight = stripos($inputstr,$delimeterRight,$posLeft+1);
    if (($posLeft===false) || ($posRight===false)) return false;
    return  substr($inputstr,$posLeft,$posRight-$posLeft);
}

或者你可以像这样使用一些

$string = "<Countries><Country><Code>AF</Code><Name>Afghanistan</Name></Coun‌try><Country><Code>AL</Code><Name>Albania</Name></Country><Country><Code>DZ</Code‌> <Name>Algeria</Name></Country><Country><Code>AS</Code><Name>American Samoa</Name></Country></Countries>";
$dom = new DOMDocument();
$dom->loadXml($string);
$countries = $dom->getElementsByTagName('Country');
echo '<select name="countries">';
foreach($countries as $country) {
    $code = $country->getElementsByTagName('Code')->item(0)->nodeValue;
    $countryName = $country->getElementsByTagName('Name')->item(0)->nodeValue;
    echo sprintf('<option value="%s">%s</option>', $code, $countryName);
}
echo '</select>';
