無法在php中引用xml標記中的冒號

Question

我需要一些替代結腸的方法，或者找到一種處理結腸的方法。 該標簽在多個其他標簽內。 這個XML就是問題所在：

<ns2:Amount>9.99</ns2:Amount>

這是完整的xml

我需要在PHP中有amount = 9.99 。

Answer 1

使用基本的PHP嘗試一下：

$subject = "<ns2:Amount>9.99</ns2:Amount>
<ns2:Test>ABCD</ns2:Test>"; // suppose you have two tags
preg_match_all('/<[^:]*:([^>]*)>(.*)<\/[^>]*>/', $subject, $matches); // matching

$i = 1;
$ii = 0;
foreach ($matches as $key => $value) {          
    $newArr[$matches[$i][$ii]] = $matches[$ii][$ii];            
    $ii++;
    $i++;
}

$result = array_filter($newArr); 
foreach($result as $key => $value){
  echo $key." = ".$value. "<br/>";
}

結果是：

Amount = 9.99
Test = ABCD

Answer 2

我能夠創建一個使我忽略命名空間的代碼。 這就是它的樣子。

$Amount = $xml->GetMatchingProductForIdResult[0]->Products->Product->AttributeSets->children('ns2', true)->ItemAttributes->Binding->Amount;
