我使用PHP simplexml的庫來解析它,如下所示:(注意有兩個類別節點第一類包含兩個「。產品」的孩子。我的目標是獲得一個包含第一的那兩個孩子的數組‘類別’
$xml = simplexml_load_file($xml_file) or die ("unable to load XML File!".$xml_file);
//for each product, print out info
$cat = array();
foreach($xml->category as $category)
{
if($category['id'] == 100)
{
$cat = $category;
break;
}
}
$prod_arr = $category->product;
這是問題所在。我期待着與這兩種產品的兒童,但其只返回一個產品陣列。什麼我是做錯了還是這是一個PHP的錯誤?請幫助!
永遠不要忘記埋怨代碼之前驗證XML文件。這很簡單,只需用firefox打開你的文件(或者在Linux下嘗試xmllint命令),它會告訴你錯誤出現在哪裏。 – OcuS 2010-01-21 08:22:58
我根據你的編輯修復了我的代碼:) – OcuS 2010-01-21 08:28:12
