simplexml的獲取節點的值，接下來將匹配節點

Question

我想知道如果我能得到一個相鄰節點的值

<item> 
    <title>Cell Phone Plans That Make You Go Hmmm</title> 
    <link>http://www.articlegeek.com/computers/telecommunication_articles/10574- cellphoneplanst.htm</link> 
    <description>Cell phone plans across the globe vary a great deal. Some say that cell phone plans in the US are more costly. However, there are some advantages to the cell phone plans in the US which may balance the difference.</description> 
</item> 

這是我的查詢來獲取描述的內容，但我想要的鏈接，以及匹配說明。

$userIN = "cell"; 
    $nod2 = $xml->xpath 
    ("//description 
       [text( 
       [contains 
       (translate(.,'ABCDEFGHJIKLMNOPQRSTUVWXYZ', 'abcdefghjiklmnopqrstuvwxyz'), 
        '".$userIN."')]]");

我借其他主題的這一回答：

SimpleXML get next/prev node

希望這有助於。

$xmlData = new SimpleXMLElement(file_get_contents("data.xml")); 
$index = 0; 
foreach($xmlData->row as $item) { 
    if ($item->url == $_GET['id']) { 
     // show photo 
     $title = $item->title; 

     $prev = $xmlData->row[$index-1]; 
     $next = $xmlData->row[$index+1]; 
    } 
    $index++; 
}
