PHP-从HTML数组子项中提取若干信息

我得到了一个名为$topPaid的数组：

Array

    [0] => <li>

但我总是会遇到这样的错误：我试图访问一个非成员对象。我应该逐行解析每个数组元素并解析它的行内容，还是用什么更好的方法来获取信息

Greetz，

我没有尝试您的代码，但在我看来，错误是一致的：

$xml = simplexml_load_string($key);

应该是：

$xml = simplexml_load_string($value);

---

如果传递给函数的文本不是有效的XML，

应该是

通过检查以下行来解决：

foreach($topPaid as $key => $value)
{
    foreach(preg_split("/((\r?\n)|(\r\n?))/", $value) as $line)
    {
        $difline = strip_tags($line);
        if(strpos($line, '<a class="livelink" href="#%21/') !== false)
        {
            $link = explode('href="', $line);
            $link = substr($link[1], 0, -2);
            // https://www.assetstore.unity3d.com/en/#!/content/4243
            $link = str_replace('#%21', 'https://www.assetstore.unity3d.com/en/#!', $link);
            //print_r($link);
        }
        else if(strpos($line, '<span title') !== false)
        {
            $title = explode('title=', $line);
            $title = explode('class=', $title[1]);
            $title = $title[0];
            //print_r($title);
        }
        else if($difline == $line)
        {
            $type = $line;
            //print_r($type);
        }
    }
}

foreach（$topPaid作为$key=>$value）
{
foreach（preg_split（“/（\r？\n）|（\r\n？）/”，$value）作为$line）
{
$difline=带标签（$line）；
如果（strpos（$line，'仍然得到“对非对象上的成员函数xpath（）的调用”。.function
simplexml\u load\u string
在失败时返回
FALSE
。是否可以检查输入（
$value
）？
标记应为有效的XML格式。
foreach($topPaid as $key => $value)
{
    foreach(preg_split("/((\r?\n)|(\r\n?))/", $value) as $line)
    {
        $difline = strip_tags($line);
        if(strpos($line, '<a class="livelink" href="#%21/') !== false)
        {
            $link = explode('href="', $line);
            $link = substr($link[1], 0, -2);
            // https://www.assetstore.unity3d.com/en/#!/content/4243
            $link = str_replace('#%21', 'https://www.assetstore.unity3d.com/en/#!', $link);
            //print_r($link);
        }
        else if(strpos($line, '<span title') !== false)
        {
            $title = explode('title=', $line);
            $title = explode('class=', $title[1]);
            $title = $title[0];
            //print_r($title);
        }
        else if($difline == $line)
        {
            $type = $line;
            //print_r($type);
        }
    }
}
