标签： php xml parsing curl soap

soap xml响应如下：

 <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Articles数组：

<item xsi:type="NS3:TArticleInfo">
    <ArticleId xsi:type="xsd:long">5000001716</ArticleId>
    <ArticleName xsi:type="xsd:string">Coca Cola</ArticleName>

如何在php curl中解析此soap XML响应以获取Articles数组数据？我已经尝试过SimpleXMLElement，但是无法解析。

我已经浏览了很多答案，但是无法获得正确的解析技术。如果可以，我应该使用Xpaths，然后如何创建一个XPath来解析articles数组？

1 个答案:

答案 0 :(得分：1)

使用XPath和SimpleXML的简单解决方案，从XML的角度来看，它不涉及XPath本身的名称空间。这将加载XML，然后查找具有直接后代<return>的元素<Articles>。当xpath()返回节点列表时，它仅选择第一个节点（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;
}

通过测试数据可以得出...
