Question

目前我有一个这样的DOM：

<div class="col-sm-4">
    <ul class="unstyled-list list-medium">
        <li><i class="fa fa-chevron-right fs-small"></i> ABCD </li>
        <li><i class="fa fa-chevron-right fs-small"></i> EFDG </li>
        <li><i class="fa fa-chevron-right fs-small"></i> WXYZ </li>
        <li><i class="fa fa-chevron-right fs-small"></i> TYUIOP </li>
        <li><i class="fa fa-chevron-right fs-small"></i> 12345 </li>
        <li><i class="fa fa-chevron-right fs-small"></i> 67890 </li>
    </ul>
</div>

然后我使用简单HTML DOM解析器通过我的代码获取“ i”标签的值：

$html = file_get_html('abc.com');
$list = $html->find('div[class="col-sm-4"]',0);
$list1 = $list->find('ul[class="unstyled-list list-medium"]',0);
foreach ($list1->find('li') as $li) {
    foreach ($li->find('i[class="fa fa-chevron-right fs-small"]',0) as $i) {
        echo $i;
    }
}

当我运行它时，它仍然会返回结果，但是还会出现类似以下错误：

我搜索起来很疯狂，但仍然不知道为什么我的foreach循环会返回这样的错误？
