問題描述

我有這個丑陋的 XML，它上面有很多命名空間，當我嘗試用 simpleXML 加載它時，如果我指出第一個命名空間，我會得到一個 xml 對象，但是跟隨帶有其他命名空間的標簽不會進入目的.

I have this ugly XML which has alot of namespaces on it, when I try to load it with simpleXML if i indicate the first namespace I'd get an xml object ,but following tags with other namespaces would not make it to the object.

如何解析這個 XML?

How can I parse this 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>

我正在嘗試使用以下代碼解析它

im trying to parse it with the following code

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

但 $xml 對象將只包含以下內容

but the $xml object would only contain the following

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

    [Body] => SimpleXMLElement Object
        (
        )

)

推薦答案

我認為您需要使用 XPath 注冊命名空間和訪問權限.像下面這樣的東西應該會讓你開始(我沒有能力測試這個).

I think you need to register the namespacing and access with XPath. Something like the following should get you going (I haven't the facility to test this).

$xml = simplexml_load_string($res, NULL, NULL, "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');

然后您可以執行以下操作:

Then you can do something like:

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

考慮一下，您可能不需要注冊命名空間，因為它們已經存在于 XML 中.雖然不確定，但需要測試.

You may not need to register the namespacing, thinking about it, as they are alredy present in the XML. Not sure on this though, would need to test.

希望這會有所幫助.
