Php 选择xPath类型的第n个下一个同级

我需要的是在xml提要中搜索一个值，并根据该值更改同级的值

我有一个这样的结构

<properties>
    <property name="sport">
        <value>Football</value>
    </property>
    <property name="player">
        <value>Lionel Messi</value>
    </property>
    <property name="nationality">
        <value>Argentine</value>
    </property>
    <property name="club">
        <value>FC Barcelona</value>
    </property>
    <property name="position">
        <value>Forward</value>
    </property>
</properties>

我以为这样应该行得通，但不知为什么不行，我也不知道为什么

$xml_src = 'players.xml';
$document = new DOMDocument();
$document->load($xml_src);
$xpath = new DOMXpath($document);

foreach($xpath->query('//property[@name="player"]') as $node){
    if(array_key_exists(trim($node->nodeValue), $position_replacements)){
        $target = $xpath->query('following-sibling::property[@name="position"]/value/text()', $node);
        $target->parentNode->replaceChild(
            $document->createTextNode($position_replacements[trim($node->textContent)]),
            $target
        );
    }
}

到目前为止，我知道问题出在

$target

查询中，但我不知道有什么方法可以解决这个问题。我做错了什么

我刚刚收到一张白纸，一个晚上的睡眠为我提供了解决问题的见解。我忘了选择te项，因此有效的代码是

$xml_src = 'players.xml';
$document = new DOMDocument();
$document->load($xml_src);
$xpath = new DOMXpath($document);

foreach($xpath->query('//property[@name="player"]') as $node){
    if(array_key_exists(trim($node->nodeValue), $position_replacements)){
        $target = $xpath->query(
            'following-sibling::property/value/text()',
            $node->parentNode
        )->item(3);
        $target->parentNode->replaceChild(
            $document->createTextNode($position_replacements[trim($node->textContent)]),
            $target
        );
    }
}

您想从xPath中得到什么？我想替换

数组中出现

值的每个

元素的te值。

$xml_src = 'players.xml';
$document = new DOMDocument();
$document->load($xml_src);
$xpath = new DOMXpath($document);

foreach($xpath->query('//property[@name="player"]') as $node){
    if(array_key_exists(trim($node->nodeValue), $position_replacements)){
        $target = $xpath->query(
            'following-sibling::property/value/text()',
            $node->parentNode
        )->item(3);
        $target->parentNode->replaceChild(
            $document->createTextNode($position_replacements[trim($node->textContent)]),
            $target
        );
    }
}
