问题描述
我已经检查了多个示例和 w3Schools 教程,但我无法弄清楚 SOAP 响应的结构.我已经 10 多年没有接触过 php/xml,所以你可以认为我是初学者.
I have checked multiple examples and the w3Schools tutorial but I can't figure out the structure of the SOAP response. I haven't touch php/xml in more than 10 years so you can consider me a beginner.
这是我得到的回复样本

我尝试使用以下代码从 table8
获取 标记:
I have tried to get the <MPH>
tag from table8
using this code:
$client = new soapclient("http://www.multiprets.net/api/ws/services.asmx?wsdl");
$objectresult = $client->Recupere_meilleurs_Taux(array('Code_businessID'=> '**LoginString**','trace' => 1));
$resultat = simplexml_load_string($objectresult->Recupere_meilleurs_TauxResult->any);
foreach ($resultat->xpath('//Table[@id='Table8']') as $product){ echo $product->MPH."< br/ >"; }
无济于事,因为它没有返回任何结果.如果我从 xpath 中删除属性并只保留 //Table
我会从所有表中获得 MPH
,所以我确定它与属性 @id
To no avail as it's not returning any result. If I remove the attribute from the xpath and only keep //Table
I get the MPH
from all the table, so I am sure it's something with the attribute @id

推荐答案
这里的问题是你的属性有一个命名空间,所以你需要用 SimpleXML XPath 注册 ns 并在你的 XPath 查询中使用它.
The problem here is that your attribute has a namespace, so you need to register the ns with SimpleXML XPath and use it in your XPath query.
这个元素为其后代声明了两个命名空间:
This element declares two namespaces for its descendants:
<diffgr:diffgram
xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"
xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1">
要使用 SimpleXML 注册这些命名空间,您需要使用函数 registerXPathNamespace代码>
.根据您正在执行的其他查询,您可能想要注册两个命名空间.对于您的查询,您需要 urn:schemas-microsoft-com:xml-diffgram-v1
(diffgr
) 命名空间;像这样注册:
To register those namespaces with SimpleXML, you need to use the function registerXPathNamespace
. Depending on what other queries you're doing, you might want to register both namespaces. For your query, you need the urn:schemas-microsoft-com:xml-diffgram-v1
(diffgr
) namespace; register it like so:
$sxe = new SimpleXMLElement($your_xml_here);
$sxe->registerXPathNamespace('d', 'urn:schemas-microsoft-com:xml-diffgram-v1');
现在您可以访问 diffgr
命名空间中的任何元素或属性,方法是在其前面加上字母 d
.下面是一个使用 Table
元素和 id Table1
的例子:
Now you can access any element or attribute in the diffgr
namespace by prefixing it with the letter d
. Here's an example using the Table
element with id Table1
:
$tables = $sxe->xpath('//Table[@d:id="Table1"]');
foreach ($tables as $t) {
echo $t->ProductSequence . PHP_EOL;
}
输出:
A1999
