用html解析html代碼錯誤問題

Question

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

但是，當我寫的代碼，

$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;} 

我得到了錯誤的一串：

人可以幫我分析這個環節，這樣我就可以保存電影的名稱和導演的名字。

在此先感謝。 Zeeshan

Answer 1

該頁面是用非常古老的HTML代碼編寫的（您可以通過FONT標記，大寫字母等進行判斷），因此<標籤以及可能的段落和其他內容都未被封閉。我建議在這種情況下使用正則表達式來查找它們。

Answer 2

你的主要問題是最後一行：

echo $movie; 

$movie是DOMNodeList一個實例，所以你不容只是呼應它，你需要得到it's元素例如像$movie->item(0)

你也可以做一個var_dump的$movie，看看你能得到什麼。

可能會忽略的警告，取決於您獲得的輸出。

Answer 3

要隱藏的錯誤，並與該代碼，只是廣告@$dom之前仍然有效，如：

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