Question

我需要解析xml文件并检索一些信息。但 Simple_XML_string函数不返回xml的所有内容。

以下是xml。

    <content type="application/xml">
    <m:properties>
    <d:ScenarioId>SAP_TOP_SELLER_HOME_PAGE</d:ScenarioId>
    <d:ResultObjectType>SAP_HYBRIS_PRODUCT</d:ResultObjectType>
    <d:ResultObjectId>37511</d:ResultObjectId>
    <d:ResultObjectScore>1.00000</d:ResultObjectScore>
    </m:properties>
    </content>
    </entry>

    </feed>
    </m:inline>
    </link>
    <content type="application/xml">
    <m:properties>
    <d:UserId/>
    <d:UserType/>
    </m:properties>
    </content>
    </entry>

我需要从content type=application获取信息，我需要检索

<m:properties>
<d:ScenarioId>SAP_TOP_SELLER_HOME_PAGE</d:ScenarioId>
<d:ResultObjectType>SAP_HYBRIS_PRODUCT</d:ResultObjectType>
<d:ResultObjectId>4934</d:ResultObjectId>
<d:ResultObjectScore>0.49999</d:ResultObjectScore>
</m:properties>

我正在尝试使用php解析（simple_xml_string函数）。

有什么想法吗？

我已经使用xpath和namespaceRegister解决了我的问题。

$xml = new SimpleXMLElement($content);
  $xml->registerXPathNamespace('m', 'http://schemas.microsoft.com/ado/2007/08/dataservices/metadata');

  $products = [];
  foreach($xml->xpath('//m:properties') as $key=>$event) {
      $products[] = strval($event->xpath('d:ResultObjectId')[0]);
  };

使用命名空间解析xml的问题
