}
I am unable get the class value. 我无法获得课程价值。 How can I achieve this? 我该如何实现?
update I am traversing through this source. 更新我正在遍历此源。 Am I wrong in logic? 我的逻辑错了吗?
From your code, I assume you are looking for <li>
elements without the class viewAll
. 从您的代码中,我假设您正在寻找没有类viewAll
<li>
元素。
You may need to check whether the class attribute exists first. 您可能需要检查class属性是否首先存在。 Try this: 尝试这个:
foreach($sub->children() as $child){
# child element doesn't have a class attrib
if (! $child->hasAttribute('class') ||
# or child element has a class but it is not 'viewAll'
($child->hasAttribute('class') && $child->getAttribute('class') !== 'viewAll'))
echo $child->plaintext."<br>";
}
}
Or, in the simple-html-dom style, this: 或者,在simple-html-dom样式中,这是:
$lis = $html->find('ul li[!class]');
foreach ($lis as $li) {
echo $li->plaintext."<br>";
}
