讀取外部網頁的內容，並獲得特定元素

Question

可能重複：
How to parse and process HTML with PHP?

我試過算出來一段時間了。我試圖不僅使用file_get_contents($url)獲取網頁的內容，還能夠繪製出特定的數據。

我對抓取內容感興趣的網頁是Craiglist。這只是一個例子。我想要形成一系列具有區域和伴隨網站的州，但我似乎找不到獲取網頁特定元素的方式。任何幫助將非常感激！

Answer 1

使用http://simplehtmldom.sourceforge.net/

實例讓所有的鏈接從http://www.craigslist.org/about/sites

include 'simple_html_dom.php'; 
$url = "http://www.craigslist.org/about/sites"; 
$html = file_get_html ($url); 
echo "<pre>"; 
foreach ($html->find ('a') as $element) { 
    $link = $element->href; 
    $link = ltrim ($link, "/"); 

    if (!preg_match ("/http/i", $link)) { 
     $link = $url . $link; 
    } 
    echo $link . PHP_EOL; 
    flush(); 
} 

輸出

$rows = $tables->item(0)->getElementsByTagName('tr'); // sample to get rows of the table element
