用html解析html代码错误问题

Question

我想解析一下链接：http://dizli.com/dizli/db.html using php。

但是，当我写的代码，

$url = "http://dizli.com/dizli/db.html"; 
$dom = new DOMDocument(); 
$html = $dom->loadHTMLFile($url); 
$dom->preserveWhiteSpace = false; 
$tables = $dom->getElementsByTagName('table'); 
$tr = $tables->item(2)->getElementsByTagName('tr'); 
$rows = $tables->item(0)->getElementsByTagName('td'); 

foreach($rows as $row) 
{ 
    $movie = $row->getElementsByTagName('b'); 
    echo $movie;} 

我得到了错误的一串：

人可以帮我分析这个环节，这样我就可以保存电影的名称和导演的名字。

在此先感谢。 Zeeshan

Answer 1

该页面是用非常古老的HTML代码编写的（您可以通过FONT标记，大写字母等进行判断），因此<标签以及可能的段落和其他内容都未被封闭。我建议在这种情况下使用正则表达式来查找它们。

Answer 2

你的主要问题是最后一行：

echo $movie; 

$movie是DOMNodeList一个实例，所以你不容只是呼应它，你需要得到it's元素例如像$movie->item(0)

你也可以做一个var_dump的$movie，看看你能得到什么。

可能会忽略的警告，取决于您获得的输出。

Answer 3

要隐藏的错误，并与该代码，只是广告@$dom之前仍然有效，如：

$html = @$dom->loadHTMLFile($url);
