我得到了一个名为$topPaid的数组：

现在我尝试取出"href"链接，"标题"和"小"文本，以使用以下代码在表格中显示它们：
foreach($topPaid as $key => $value)
{
$xml = simplexml_load_string($key);
$list = $xml->xpath("//@href");
$preparedUrls = array();
foreach($list as $item) {
$item = parse_url($item);
$preparedUrls[] = $item['scheme'] . '://' . $item['host'] . '/';
}
print_r($preparedUrls);
}
但是我总是收到尝试访问非成员对象的错误。我应该逐行解析每个数组元素并解析其行内容，还是有什么更好的方法来获取信息？
格莱兹，

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);
并且您传递给函数的文本不是有效的 XML，<br>应该是<br /> 。
通过检查以下行来解决它：
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);
}
}
}
