Question

我试图通过simplexml_load_string（）从PHP中解析来自Amazon API的XML响应。

我得到的XML看起来像这样：

<?xml version="1.0" encoding="UTF-8"?>
<GetMatchingProductForIdResponse xmlns="http://mws.amazonservices.com/schema/Products/2011-10-01">
   <GetMatchingProductForIdResult Id="xxx" IdType="SellerSKU" status="Success">
      <Products>
         <Product>
            <Identifiers>
               <MarketplaceASIN>
                  <MarketplaceId>xxxx</MarketplaceId>
                  <ASIN>xxx</ASIN>
               </MarketplaceASIN>
            </Identifiers>
            <AttributeSets>
               <ns2:ItemAttributes xmlns:ns2="http://mws.amazonservices.com/schema/Products/2011-10-01/default.xsd" xml:lang="de-DE">
                  <ns2:Binding>Elektronik</ns2:Binding>
                  <ns2:Brand>Panasonic</ns2:Brand>
                  <ns2:Feature>xx</ns2:Feature>
                  <ns2:Feature>xxx</ns2:Feature>
                  <ns2:Feature>xxx</ns2:Feature>
                  <ns2:Feature>xxx</ns2:Feature>
                  <ns2:Feature>xxx</ns2:Feature>
                  <ns2:Label>Panasonic</ns2:Label>
                  <ns2:Manufacturer>Panasonic</ns2:Manufacturer>
                  <ns2:PackageDimensions>
                     <ns2:Height Units="inches">xx</ns2:Height>
                     <ns2:Length Units="inches">xx</ns2:Length>
                     <ns2:Width Units="inches">xxx</ns2:Width>
                  </ns2:PackageDimensions>
                  <ns2:PartNumber>xxx</ns2:PartNumber>
                  <ns2:ProductGroup>Computer &amp; Zubehör</ns2:ProductGroup>
                  <ns2:ProductTypeName>COMPUTER_COMPONENT</ns2:ProductTypeName>
                  <ns2:Publisher>Panasonic</ns2:Publisher>
                  <ns2:SmallImage>
                     <ns2:URL>xxx.jpg</ns2:URL>
                     <ns2:Height Units="pixels">xx</ns2:Height>
                     <ns2:Width Units="pixels">xx</ns2:Width>
                  </ns2:SmallImage>
                  <ns2:Studio>Panasonic</ns2:Studio>
                  <ns2:Title>xxx</ns2:Title>
               </ns2:ItemAttributes>
            </AttributeSets>
            <Relationships />
            <SalesRankings />
         </Product>
      </Products>
   </GetMatchingProductForIdResult>
   <ResponseMetadata>
      <RequestId>xx</RequestId>
   </ResponseMetadata>
</GetMatchingProductForIdResponse>

我的PHP代码：

$response = $service->GetMatchingProductForId($request);  //making the call
$response = $response->toXML();
$response = simplexml_load_string($response);       
var_dump($response);

遗憾的是，如var_dump中所见，AttributeSets无法转换为对象。

object(SimpleXMLElement)#9 (2) {
  ["GetMatchingProductForIdResult"]=>
  object(SimpleXMLElement)#4 (2) {
    ["@attributes"]=>
    array(3) {
      ["Id"]=>
      string(5) "xxx"
      ["IdType"]=>
      string(9) "SellerSKU"
      ["status"]=>
      string(7) "Success"
    }
    ["Products"]=>
    object(SimpleXMLElement)#14 (1) {
      ["Product"]=>
      object(SimpleXMLElement)#18 (4) {
        ["Identifiers"]=>
        object(SimpleXMLElement)#23 (1) {
          ["MarketplaceASIN"]=>
          object(SimpleXMLElement)#29 (2) {
            ["MarketplaceId"]=>
            string(14) "xxx"
            ["ASIN"]=>
            string(10) "xxxx"
          }
        }
        ["AttributeSets"]=>
        object(SimpleXMLElement)#37 (0) {
        }
        ["Relationships"]=>
        object(SimpleXMLElement)#28 (0) {
        }
        ["SalesRankings"]=>
        object(SimpleXMLElement)#26 (0) {
        }
      }
    }
  }
  ["ResponseMetadata"]=>
  object(SimpleXMLElement)#12 (1) {
    ["RequestId"]=>
    string(36) "xxx"
  }
}

XML有问题吗？

Answer 1

坚持这一点，只是使用钝力而且效果很好。

$response = str_replace("ns2:","",$response);

Answer 2

有时var_dump（）不会显示所有元素（大多数元素太多或缩进太多）。它只关于视图，但你的对象将在那里，尝试只转储AttributeSets self

Answer 3

您可以在children上致电SimpleXMLElement

$xml = <<<EOF
<AttributeSets>
   <ns2:ItemAttributes xmlns:ns2="http://mws.amazonservices.com/schema/Products/2011-10-01/default.xsd" xml:lang="de-DE">
      <ns2:Binding>Elektronik</ns2:Binding>
      <ns2:Brand>Panasonic</ns2:Brand>
      <ns2:Feature>xx</ns2:Feature>
      <ns2:Feature>xxx</ns2:Feature>
      <ns2:Feature>xxx</ns2:Feature>
      <ns2:Feature>xxx</ns2:Feature>
      <ns2:Feature>xxx</ns2:Feature>
      <ns2:Label>Panasonic</ns2:Label>
      <ns2:Manufacturer>Panasonic</ns2:Manufacturer>
      <ns2:PackageDimensions>
         <ns2:Height Units="inches">xx</ns2:Height>
         <ns2:Length Units="inches">xx</ns2:Length>
         <ns2:Width Units="inches">xxx</ns2:Width>
      </ns2:PackageDimensions>
      <ns2:PartNumber>xxx</ns2:PartNumber>
      <ns2:ProductGroup>Computer &amp; Zubehör</ns2:ProductGroup>
      <ns2:ProductTypeName>COMPUTER_COMPONENT</ns2:ProductTypeName>
      <ns2:Publisher>Panasonic</ns2:Publisher>
      <ns2:SmallImage>
         <ns2:URL>xxx.jpg</ns2:URL>
         <ns2:Height Units="pixels">xx</ns2:Height>
         <ns2:Width Units="pixels">xx</ns2:Width>
      </ns2:SmallImage>
      <ns2:Studio>Panasonic</ns2:Studio>
      <ns2:Title>xxx</ns2:Title>
   </ns2:ItemAttributes>
</AttributeSets>
EOF;

$sxe = new SimpleXMLElement($xml);
$ns2 = $sxe->children('ns2', TRUE);

var_dump(count($ns2));

// prints int(1)

在php文档中： http://php.net/manual/en/simplexmlelement.children.php

public SimpleXMLElement SimpleXMLElement::children ([ string $ns [, bool $is_prefix = false ]] )

XML未通过simplexml_load_string（）正确转换为对象
