Question

我正在使用XML DOM和PHP构建脚本

$troops = $xmlfile->getElementsByTagName("troops");

foreach( $troops as $troop ) {

    $sniper = $troop->getElementsByTagName( "sniper" );
    $otroop[0] = $sniper->item(0)->nodeValue;

    $riffle = $troop->getElementsByTagName( "riffle" );
    $otroop[1] = $riffle->item(0)->nodeValue;

    $riffle = $troop->getElementsByTagName( "shooter" );
    $otroop[2] = $riffle->item(0)->nodeValue;

    $riffle = $troop->getElementsByTagName( "missle" );
    $otroop[3] = $riffle->item(0)->nodeValue;

    $tank = $troop->getElementsByTagName( "tank" );
    $otroop[4] = $tank->item(0)->nodeValue;

    $bomber = $troop->getElementsByTagName( "bomber" );
    $otroop[5] = $bomber->item(0)->nodeValue;

    $patrol = $troop->getElementsByTagName( "patrol" );
    $otroop[6] = $patrol->item(0)->nodeValue;

    $surveillance = $troop->getElementsByTagName( "surveillance" );
    $otroop[7] = $surveillance->item(0)->nodeValue;

}

XML

<troops>
    <sniper level="5">2</sniper>
    <riffle level="0">0</riffle>
    <shooter level="0">0</shooter>
    <missle level="0">0</missle>
    <tank level="0">0</tank>
    <bomber level="0">0</bomber>
    <patrol level="0">0</patrol>
    <surveillance level="0">0</surveillance>
</troops>

我想能够拉动每个节点的水平，我也尝试了

$oresearch[0] = $sniper->getAttribute("level");

但这不起作用，这里的任何建议都会有所帮助

Answer 1

在您的代码中$sniper是DOMNodeList。您可以正确处理第一个节点的值：

$sniper->item(0)->nodeValue

对于第一个节点的属性，您必须这样做：

$sniper->item(0)->getAttribute('level')

获取子节点XML的属性 - PHP
