PHP简单的htmldom解析器将元素放在当前元素的后面

我有一个HTML:

<div class="card">
    <span class="label">Name:</span><span>John Doe</span>
    <span class="label">Address:</span><span>Some address...</span>
    <span class="label">Email:</span><span>email@example.com</span>
    <span class="label">Tel:</span><span>xxxxxxxxx</span>
</div>



$spans = $html->find('.label');
foreach ($spans as $span) {
    if ($span->plaintext == 'Name:') $name = John Doe;
    (ALWAYS THE SPAN NEXT TO THE CURRENT .label SPAN)
}

现在,如何获取当前范围旁边的范围值(纯文本)。

注:标签的顺序和它们的值是不断变化的,有时是地址前的电话。。。
