Php 如何从stdClass对象数组获取的xml对象中检索combox中的CountryName列表？

问题：下面给出了SOAP请求的响应，CountryList响应是带有CountryCode和CountryName的XML对象。那么，如何从结果中显示包含CountryName的组合框呢

使用你给我们的字符串，你可以做到这一点

$str = "<Countries><Country><Code>AF</Code><Name>Afghanistan</Name></Coun‌​try><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);
}

或者你可以用这样的东西

$string = "<Countries><Country><Code>AF</Code><Name>Afghanistan</Name></Coun‌​try><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>';

我希望这里并没有为国家代码显示一些字符串分隔符。根据SOAP服务提供商的说法，“CountryList”是xml类型。但是他们在他们的帮助文档中提到了，比如（回复）“CountryList”：“AFAfghanistanALAlbanaDZAlegariaASAmerican萨摩亚”，但是当我使用print nl2br打印时（print_r（$resp_CountryList，true））；它显示如上面QS所示的结果。使用echo“”；打印（$xml）以查看正确的格式。给我们最原始的格式。不要试图纠正它。当我试图按照@Demodave所说的那样显示时，输出来自阿富汗、阿根廷、阿尔及利亚、美国、萨摩亚、阿根廷、马尔门尼亚瓦鲁巴奥、澳大利亚、巴西、巴西、巴西、巴林、孟加拉国、巴巴多斯、白俄罗斯（白俄罗斯）Bebelgiumbzbelizebjbbenibermudabthutanbobolibabosnia和Herzegowinabwbotswanabbouvet群岛……非常感谢。它现在运行良好。。。！再次感谢。@BINODDEKA如果这是一个可接受的答案，你应该检查它。
