我在理解childNodes中存储的内容时遇到了一些麻烦.理想情况下,我想在每个子节点上做另一个xquery,但似乎无法直截了当.这是我的情景：
数据：

<div class="something">
    <h3>
        <a href="link1.htML">Link text 1</a>
    </h3>
    <div class"somethingelse">Something else text 1</div>
</div>
<div class="something">
    <h3>
        <a href="link2.html">Link text 2</a>
    </h3>
    <div class"somethingelse">Something else text 2</div>
</div>
<div class="something">
    <h3>
        <a href="link3.html">Link text 3</a>
    </h3>
    <div class"somethingelse">Something else text 3</div>
</div>

和代码：

$html = new DOMDocument();
$html->loadhtmlFile($local_file);
$xpath = new DOMXPath( $html );
$nodelist = $xpath->query( "//div[@class='something']");
foreach ($nodelist as $n) {
    Can I run another query here? }

对于“某事物”的每个元素(即$n),我想要访问两段文本和href的值.我尝试使用childNode和另一个xquery,但无法获得任何工作.任何帮助将不胜感激！

foreach ($nodelist as $n)
{
    $other_nodes = $xpath->query('div[@class="somethingelse"]',$n);

    echo $other_nodes->length;
}
