Scan entire XML file and grab only nodes needed

本文关键字：抓取节点 XML 文件扫描 | 更新日期: 2023-09-27

请忽略XML数据的语义。我想扫描整个xml文件并仅获取香蕉值并将它们存储为PHP中的数组。

<?xml version="1.0" encoding="UTF-8" ?>
<data>
<fruits>
    <fruit id="1" >
        <aisle1>
            <apple>aa</apple>
            <banana>ab</banana>
            <cherry>ac</cherry>
            <damson>ad</damson>
        </aisle1>
        <aisle2>
            <apple>none</apple>
            <banana>3708650582321691833</banana>
            <cherry>none</cherry>
            <damson>none</damson>
        </aisle2>
        <aisle3>
            <apple>none</apple>
            <banana>3708650582321691833</banana>
            <cherry>none</cherry>
            <damson>none</damson>
        </aisle3>
    </fruit>
    <fruit id="2" >
        <aisle1>
            <apple>none</apple>
            <banana>3708650582321691833</banana>
            <cherry>none</cherry>
            <damson>none</damson>
        </aisle1>
        <aisle2>
            <apple>none</apple>
            <banana>3708650582321691833</banana>
            <cherry>none</cherry>
            <damson>none</damson>
        </aisle2>
        <aisle3>
            <apple>none</apple>
            <banana>3708650582321691833</banana>
            <cherry>none</cherry>
            <damson>none</damson>
        </aisle3>
    </fruit>
</fruits>

xPath 可以允许我这样做吗？我目前有：

$xml->xpath("//fruits//fruit//bananas->text()";

谢谢。

如果您只对该特定节点感兴趣，只需直接查询它：

$just_bunch_of_bananas = array();
$bananas = $xml->xpath('//banana'); // directly get it
foreach($bananas as $banana) { // loop each banana node :)
    echo $banana . '<br/>';
    $just_bunch_of_bananas[] = (string) $banana;
}

按行：

$rows = array();
$fruits = $xml->xpath('//fruit');
foreach($fruits as $fruit) {
    foreach($fruit as $row => $aisles) {
        $rows[] = array('apple' => (string )$aisles->apple, 'banana' => (string )$aisles->banana);
    }
}
echo '<pre>';
print_r($rows);
