我将以下内容包裹在 XML 标签中。我有一个 PHP 页面，我在其中传递了一个变量 page?id=VGS0003 - 我想在 PHP 变量中提取该节点的所有子元素以供使用。

Example: 

$realm = $account->realm;
$region = $account-region;
$race = $account->race;

我几乎尝试了所有方法，但似乎没有任何效果。 Foreach 仅 returns 最后一个节点，无论我是否在循环中放置 if 语句。

                $accountID = $_GET['id'];
                

                $xmlurl = "../config/classic/accounts.php";
                include($xmlurl);
                $packages = new SimpleXMLElement($xmlstr);

                foreach($packages->accounts->account as $account){

                    if($accountID == $account->id){

                    $accountRace = $account->race;
                    $accountRaceLowerU = strtolower($accountRace);
                    $accountRaceLowerU = str_replace(' ', '_', $accountRaceLowerU);
                    $accountGender = $account->gender;
                    $accountGenderLower = strtolower($accountGender);
                    $accountClass = $account->class;
                    $accountClassLower = strtolower($accountClass);
                    $accountFaction = $account->faction;
                    $accountScreenshotThumb = $account->images->image[0];
                    $accountScreenshot = $account->screenshot;
                    $accountSKU = $account->id;
                    $accountLevel = $account->level;
                    $accountRealm = $account->realm;
                    $accountType = $account->type;

                    }

                };

如何实现？我想要做的很简单，但似乎我已经尝试了一切。通过ID找到account节点，将子元素值保存为php变量，在页面其他地方使用

一种选择是使用 xpath "//account[id='$id']" 和您要查找的 ID。

$elements = simplexml_load_string($xmlstr);
$id = "VGS0037";
$query = "//account[id='$id']";
$account = $elements->xpath($query);
$accountRace = $account[0]->race;
echo $accountRace;

输出
