如何分析定义了多个命名空间的 SOAP xml 响应.我需要解析返回的文章数组

Question

soap xml 响应是这样的：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:NS1="urn:TPAPIPosIntfU-ITPAPIPOS">
<NS1:GetArticlesInfoResponse xmlns:NS2="urn:TPAPIPosIntfU" xmlns:NS3="urn:TPAPIPosTypesU">
<return xsi:type="NS2:TGetArticlesInfoResponse">
<ReturnCode xsi:type="xsd:int">0</ReturnCode>
<ReturnMessage xsi:type="xsd:string">ok</ReturnMessage>
<Articles xsi:type="SOAP-ENC:Array" SOAP-ENC:arrayType="NS3:TArticleInfo[x]">...</Articles>
<Extra xsi:type="SOAP-ENC:Array" SOAP-ENC:arrayType="NS3:TExtraInfo[0]"/>
</return>
</NS1:GetArticlesInfoResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

这是我需要解析的文章数组：

<item xsi:type="NS3:TArticleInfo">
<ArticleId xsi:type="xsd:long">5000001716</ArticleId>

如何在 php curl 中解析此 soap XML 响应以获取文章数组数据？我已经尝试过SimpleXMLElement，但我无法解析它。

我已经冲浪了很多寻找答案，但无法获得正确的解析技术。如果是，我应该使用 Xpath 吗，那么如何创建一个 XPath 来解析文章数组？

Answer 1

使用 XPath和 SimpleXML 的简单解决方案，从 XML 的外观来看，它们不涉及 XPath 本身的命名空间。 这将加载 XML，然后查找名为<return>的元素，该元素具有名为<Articles>的直接后代。 当xpath()返回节点列表时，它只选择第一个(使用[0])并迭代包含的<item>元素并输出<ArticleId>元素值。

$xml = simplexml_load_string($data);
$articles = $xml->xpath("//return/Articles");
foreach ( $articles[0]->item as $item )    {
echo (string)$item->ArticleId.PHP_EOL;
}

有了测试数据，这给了...

5000001716
5000001716
