我有一个丑陋的XML,上面有很多名称空间,当我尝试通过simpleXML加载它(如果我指示第一个名称空间)时,我会得到一个xml对象,但是后面带有其他名称空间的标记不会使它成为该对象。
如何解析该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>
我试图用下面的代码解析它
<?php $xml = simplexml_load_string($res,NULL,NULL,"http://schemas.xmlsoap.org/soap/envelope/"); ?>
但是$ xml对象仅包含以下内容
SimpleXMLElement Object ( [Header] => SimpleXMLElement Object ( ) [Body] => SimpleXMLElement Object ( ) )
我认为您需要注册名称空间并使用XPath进行访问。如下所示的内容应该可以帮助您(我没有设施可以对此进行测试)。
$xml = simplexml_load_string($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'); $xml->registerXPathNamespace('wsse', 'http://schemas.xmlsoap.org/ws/2002/12/secext');
然后,您可以执行以下操作:
foreach($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,也不必考虑它,因为名称空间已存在于XML中。虽然不确定,但是需要测试。
希望这可以帮助。
