解析XML与C＃多个命名空间

Question

我一直无法解析其中包含多个命名空间下面的XML：

<?xml version="1.0" encoding="UTF-8"?> 
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> 
    <s:Header> 
     <h:ServerVersionInfo xmlns:h="http://schemas.microsoft.com/exchange/services/2006/types" xmlns="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" MajorVersion="14" MinorVersion="3" MajorBuildNumber="352" MinorBuildNumber="0" Version="Exchange2010_SP2" /> 
    </s:Header> 
    <s:Body xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
     <GetMailTipsResponse xmlns="http://schemas.microsoft.com/exchange/services/2006/messages" ResponseClass="Success"> 
     <ResponseCode>NoError</ResponseCode> 
     <ResponseMessages> 
      <MailTipsResponseMessageType ResponseClass="Success"> 
       <ResponseCode>NoError</ResponseCode> 
       <m:MailTips xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages"> 
        <t:RecipientAddress xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"> 
        <t:Name /> 
        <t:EmailAddress>[email protected]</t:EmailAddress> 
        <t:RoutingType>SMTP</t:RoutingType> 
        </t:RecipientAddress> 
        <t:PendingMailTips xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types" /> 
        <t:OutOfOffice xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"> 
        <t:ReplyBody> 
         <t:Message /> 
        </t:ReplyBody> 
        </t:OutOfOffice> 
       </m:MailTips> 
      </MailTipsResponseMessageType> 
     </ResponseMessages> 
     </GetMailTipsResponse> 
    </s:Body> 
</s:Envelope> 

我试着下面的代码，但你可以看到用肥皂命名空间的作品的第一个节点不错，但此后我无法找回，我需要它是节点的节点信息 -

/s:Envelope/s:Body/GetMailTipsResponse/ResponseMessages/MailTipsResponseMessageType/m:MailTips/t:RecipientAddress/t:Message 

这里是我试过的代码：

string getXmlInfo (string resultXml) 

XmlDocument xmlDoc = new XmlDocument(); 
xmlDoc.LoadXml(resultXml); 

XmlNamespaceManager soapNsManager = new XmlNamespaceManager(xmlDoc.NameTable); 
soapNsManager.AddNamespace("s", "http://schemas.xmlsoap.org/soap/envelope/"); 
XmlNode xmlNode = xmlDoc.SelectSingleNode("//s:Envelope/s:Body", soapNsManager); //works fine - the node now contains the Xml starting with the node 

XmlNode xmlNode1 = xmlDoc.SelectSingleNode("//s:Envelope/s:Body/GetMailTipsResponse/ResponseMessages/MailTipsResponseMessageType", soapNsManager); //returns NULL 


XmlNode innerNode1 = xmlNode.SelectSingleNode("//GetMailTipsResponse/ResponseMessages/MailTipsResponseMessageType"); // returns NULL 
XmlNode innerNode2 = xmlNode.SelectSingleNode("//GetMailTipsResponse", soapNsManager); //returns NULL 

// the next line throws an exception 
//XmlNode messageNode = xmlDoc.SelectSingleNode("/s:Envelope/s:Body/GetMailTipsResponse/ResponseMessages/MailTipsResponseMessageType/m:MailTips/t:RecipientAddress/t:Message", manager); 

}

这是基于从@LocEngineer响应我的尝试：

  XmlNamespaceManager manager = new XmlNamespaceManager(xmlDoc.NameTable); 
     manager.AddNamespace("s", "http://schemas.xmlsoap.org/soap/envelope/"); 
     manager.AddNamespace("blank", "http://schemas.microsoft.com/exchange/services/2006/types"); 
     manager.AddNamespace("m", "http://schemas.microsoft.com/exchange/services/2006/types"); 
     manager.AddNamespace("t", "http://schemas.microsoft.com/exchange/services/2006/types"); 

     XmlNode messageNode = xmlDoc.SelectSingleNode("/s:Envelope/s:Body/blank:GetMailTipsResponse/blank:ResponseMessages/blank:MailTipsResponseMessageType/m:MailTips/t:OutOfOffice/t:ReplyBody/t:Message", manager); 

的messageNode显示为NULL

您还需要一个XmlNamespaceManager的前缀推出的前缀命名空间少在GetMailTipsResponse节点中，它包含XML中没有前缀的节点：

GetMailTipsResponse xmlns =“http：// schemas。 microsoft.com/exchange/services/2006/messages”

，然后用它在你的XPath适当，使用‘M’为前缀的前缀少节点：

XmlNamespaceManager soapNsManager = new XmlNamespaceManager(xmlDoc.NameTable); 
soapNsManager.AddNamespace("s", "http://schemas.xmlsoap.org/soap/envelope/"); 
soapNsManager.AddNamespace("m", "http://schemas.microsoft.com/exchange/services/2006/messages"); 
XmlNode xmlNode1 = xmlDoc.SelectSingleNode("/s:Envelope/s:Body/m:GetMailTipsResponse/m:ResponseMessages/m:MailTipsResponseMessageType", soapNsManager);
