php – 使用具有多个命名空间的SimpleXML解析XML

我有这个丑陋的 XML,它有很多命名空间,当我尝试加载它与simpleXML如果我指示第一个命名空间我会得到一个xml对象,但跟随其他命名空间的标签不会使它对象.

如何解析这个XML？

<?xml version="1.0" encoding="UTF-8"?>
<soap-env:Envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">
    <soap-env:Header>
        <eb:MessageHeader xmlns:eb="http://www.ebxml.org/namespaces/messageHeader" eb:version="1.0" soap-env:mustUnderstand="1">
            <eb:From>
                <eb:PartyId eb:type="URI">wscompany.com</eb:PartyId>
            </eb:From>
            <eb:To>
                <eb:PartyId eb:type="URI">mysite.com</eb:PartyId>
            </eb:To>
            <eb:CPAId>something</eb:CPAId>
            <eb:ConversationId>moredata.com</eb:ConversationId>
            <eb:Service eb:type="compXML">theservice</eb:Service>
            <eb:Action>theaction</eb:Action>
            <eb:MessageData>
                <eb:MessageId>a certain messageid</eb:MessageId>
                <eb:Timestamp>2009-04-11T18:43:58</eb:Timestamp>
                <eb:RefToMessageId>mid:areference</eb:RefToMessageId>
            </eb:MessageData>
        </eb:MessageHeader>
        <wsse:Security xmlns:wsse="http://schemas.xmlsoap.org/ws/2002/12/secext">
            <wsse:BinarySecurityToken valueType="String" EncodingType="wsse:Base64Binary">an impresive binary security toekn</wsse:BinarySecurityToken>
        </wsse:Security>
    </soap-env:Header>
    <soap-env:Body>
        <SessionCreateRS xmlns="http://www.opentravel.org/OTA/2002/11" version="1" status="Approved">
            <ConversationId>the goodbye token</ConversationId>
        </SessionCreateRS>
    </soap-env:Body>
</soap-env:Envelope>

我试图解析它与以下代码

<?PHP
$xml = simplexml_load_string($res,NULL,"http://schemas.xmlsoap.org/soap/envelope/");
?>

但$xml对象只包含以下内容

SimpleXMLElement Object
(
    [Header] => SimpleXMLElement Object
        (
        )

    [Body] => SimpleXMLElement Object
        (
        )

)

我想你需要注册XPath的命名空间和访问.像以下这样的东西应该让你走(我没有能力测试这个).

$xml = simplexml_load_string($res,"http://schemas.xmlsoap.org/soap/envelope/");
$xml->registerXPathNamespace('soap-env','http://schemas.xmlsoap.org/soap/envelope/');
$xml->registerXPathNamespace('eb','http://www.ebxml.org/namespaces/messageHeader');
$xml->registerXPathNamespace('wsse','http://schemas.xmlsoap.org/ws/2002/12/secext');

那么你可以做一些像：

foreach($xml->xpath('//eb:MessageHeader') as $header)
{
    var_export($header->xpath('//eb:CPAId')); // Should output 'something'.
}

您可能不需要注册名称空间,考虑它,因为它们是XML中存在的alredy.不确定,但是,需要测试.

希望这可以帮助.
