如何通过给定的父ID将XML子节点存储在PHP变量中？

Question

<account VGS0035="VGS0035">        <realm>Smolderweb</realm>        <realmint>smolderweb-us</realmint>        <type>PvP</type>        <race>Undead</race>        <gender>Male</gender>        <class>Mage</class>        <faction>Horde</faction>        <level>60</level>        <description>(60% mount, green/blue gear)</description>        <price>210</price>        <stock>1</stock>        <id>VGS0035</id>        <screenshot>https://vanilla.games/wp-content/uploads/2019/08/wow-classic-mage.jpg</screenshot>    </account>    <account VGS0036="VGS0036">        <realm>Faerlina</realm>        <realmint>faerlina-us</realmint>        <type>PvP</type>        <race>Undead</race>        <gender>Male</gender>        <class>Mage</class>        <faction>Horde</faction>        <level>60</level>        <description>(100% mount, epic/blue gear, Tailoring 300, First Aid 225, MC+ONY+BWL attuned, 150 gold)</description>        <price>400</price>        <stock>1</stock>        <id>VGS0036</id>        <screenshot>https://i.imgur.com/cdeAdwe.jpg</screenshot>    </account>    <account VGS0037="VGS0037">        <realm>Faerlina</realm>        <realmint>faerlina-us</realmint>        <type>PvP</type>        <race>Undead</race>        <gender>Male</gender>        <class>Mage</class>        <faction>Horde</faction>        <level>60</level>        <description>(60% mount, green/blue/epic gear, 100 gold)</description>        <price>250</price>        <stock>1</stock>        <id>VGS0037</id>        <screenshot>https://vanilla.games/wp-content/uploads/2019/08/wow-classic-mage.jpg</screenshot>    </account>我将以下内容封装在 XML 标签中。我有一个 PHP 页面，我在其中传递变量 page?id=VGS0003 - 我想提取 PHP 变量中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。无论我是否在循环中放置 if 语句，Foreach 都只返回最后一个节点。

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

Undead
