Question

<?php$xml ='<?xml version="1.0" encoding="UTF-8"?><env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope" xmlns:ns1="http://www.promostandards.org/WSDL/ProductDataService/1.0.0/SharedObjects/" xmlns:ns2="http://www.promostandards.org/WSDL/ProductDataService/1.0.0/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">    <env:Body>        <ns2:GetProductResponse>            <ns2:Product>                <ns1:productId>1322059</ns1:productId>                <ns2:productName>Smart WiFi Security Camera</ns2:productName>                <ns2:productBrand>AAkron Line</ns2:productBrand>                <ns2:export>false</ns2:export>                <ns2:ProductCategoryArray>                    <ns2:ProductCategory>                        <ns2:category>Cameras, Safety, Health Care, Insurance, Finance, Tech Industry, NEW for 2018, New for 2019</ns2:category>                        <ns2:subCategory>N/A</ns2:subCategory>                    </ns2:ProductCategory>                </ns2:ProductCategoryArray>            </ns2:Product>        </ns2:GetProductResponse>    </env:Body></env:Envelope>';//header("Content-type: text/xml");//echo $xml;$data_xml = simplexml_load_string($xml);print_r($data_xml);?>我已经尝试了其他参考资料中的所有内容，但没有任何效果。它输出一个空数组。

Answer 1

如果您使用DOMDocument并且DOMXPath可以使用 XPath 查询从 XML 中找到您需要的信息。

$xml ='<?xml version="1.0" encoding="UTF-8"?>

<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope" xmlns:ns1="http://www.promostandards.org/WSDL/ProductDataService/1.0.0/SharedObjects/" xmlns:ns2="http://www.promostandards.org/WSDL/ProductDataService/1.0.0/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

    <env:Body>

        <ns2:GetProductResponse>

            <ns2:Product>

                <ns1:productId>1322059</ns1:productId>

                <ns2:productName>Smart WiFi Security Camera</ns2:productName>

                <ns2:productBrand>AAkron Line</ns2:productBrand>

                <ns2:export>false</ns2:export>

                <ns2:ProductCategoryArray>

                    <ns2:ProductCategory>

                        <ns2:category>Cameras, Safety, Health Care, Insurance, Finance, Tech Industry, NEW for 2018, New for 2019</ns2:category>

                        <ns2:subCategory>N/A</ns2:subCategory>

                    </ns2:ProductCategory>

                </ns2:ProductCategoryArray>

            </ns2:Product>

        </ns2:GetProductResponse>

    </env:Body>

</env:Envelope>';

$dom=new DOMDocument;

$dom->loadXML( $xml );

$xp=new DOMXPath( $dom );

$xp->registerNamespace('ns1','http://www.promostandards.org/WSDL/ProductDataService/1.0.0/SharedObjects/');

$xp->registerNamespace('ns2','http://www.promostandards.org/WSDL/ProductDataService/1.0.0/');

$xp->registerNamespace('xsi','http://www.w3.org/2001/XMLSchema-instance');

$xp->registerNamespace('env','http://www.w3.org/2003/05/soap-envelope');

$products=$xp->query('//ns2:Product');

if( $products->length > 0 ){

    foreach( $products as $product ){

        $id=$xp->query( 'ns1:productId', $product )->item(0)->nodeValue;

        $name=$xp->query( 'ns2:productName', $product )->item(0)->nodeValue;

        $brand=$xp->query( 'ns2:productBrand', $product )->item(0)->nodeValue;

        $export=$xp->query( 'ns2:export', $product )->item(0)->nodeValue;

        $category=$xp->query( 'ns2:ProductCategoryArray/ns2:ProductCategory/ns2:category', $product )->item(0)->nodeValue;

        $subcategory=$xp->query( 'ns2:ProductCategoryArray/ns2:ProductCategory/ns2:subCategory', $product )->item(0)->nodeValue;

        echo $id, $name, $brand, $category, $subcategory;

    }

}

输出：

Answer 2

您还可以使用 SimpleXML 和Xpath。

function getNsValue($xml, $path, $index = 0){

  return (string)$xml->xpath($path)[$index];

}

xml测试数据：

$xml ='<?xml version="1.0" encoding="UTF-8"?>

<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope" xmlns:ns1="http://www.promostandards.org/WSDL/ProductDataService/1.0.0/SharedObjects/" xmlns:ns2="http://www.promostandards.org/WSDL/ProductDataService/1.0.0/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

    <env:Body>

        <ns2:GetProductResponse>

            <ns2:Product>

                <ns1:productId>1322059</ns1:productId>

                <ns2:productName>Smart WiFi Security Camera</ns2:productName>

                <ns2:productBrand>AAkron Line</ns2:productBrand>

                <ns2:export>false</ns2:export>

                <ns2:ProductCategoryArray>

                    <ns2:ProductCategory>

                        <ns2:category>Cameras, Safety, Health Care, Insurance, Finance, Tech Industry, NEW for 2018, New for 2019</ns2:category>

                        <ns2:subCategory>N/A</ns2:subCategory>

                    </ns2:ProductCategory>

                </ns2:ProductCategoryArray>

            </ns2:Product>

        </ns2:GetProductResponse>

    </env:Body>

</env:Envelope>';

$data_xml = simplexml_load_string($xml);

例子：

$category = getNsValue($data_xml,'//ns2:category');

$productId = getNsValue($data_xml,'//ns1:productId');

var_dump($category, $productId);

/*

string(91) "Cameras, Safety, Health Care, Insurance, Finance, Tech Industry, NEW for 2018, New for 2019"

string(7) "1322059"

*/    

Answer 3

我已经使用以下代码解决了我的问题-

$response = file_get_contents($xml);

$res=simplexml_load_string($response);

print_r($res);
