使用XPath Csharp选择带有名称空间的单个xml节点

Question

为什么我的xmlNode节点总是以null结尾？ 我放入了它要求的名称空间。 以下是我已加载的xml。

 <?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns="urn:enterprise.soap.sforce.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:sf="urn:sobject.enterprise.soap.sforce.com">

                                                               <sf:Id xsi:nil="true"></sf:Id>
                                                               <sf:Description>The Product Description</sf:Description>
                                                           </sf:Product2>
                                                    </sf:PricebookEntry>
                                                 <sf:Product_Group_for_Storage_Sys__c>Some Descriptive Text</sf:Product_Group_for_Storage_Sys__c>
                                                 <sf:Product_Type_Formula__c>Enterprise</sf:Product_Type_Formula__c>
                                                 <sf:Product_Type_Text__c>Enterprise</sf:Product_Type_Text__c>
                                                 <sf:Product_Type__c>Enterprise</sf:Product_Type__c>

                                             </records>
                                          <size>1</size>
                                      </sf:OpportunityLineItems>
                                   <sf:PartnerAccount xsi:type="sf:Account">
                                          <sf:Id xsi:nil="true"></sf:Id>
                                          <sf:Account_ID__c>IDXXXX</sf:Account_ID__c>
                                      </sf:PartnerAccount>
                                   <sf:Partner_Account_Name__c>The Partner Name</sf:Partner_Account_Name__c>
                               </records>
                            <size>1</size>
                        </result>
                 </queryResponse>
          </soapenv:Body>
   </soapenv:Envelope>

xmlSoapRequest.LoadXml(strResultString);
            XmlNamespaceManager man = new XmlNamespaceManager(xmlSoapRequest.NameTable);
            man.AddNamespace("sf", "urn:sobject.enterprise.soap.sforce.com");
            man.AddNamespace("soapenv", "http://schemas.xmlsoap.org/soap/envelope/");



            XmlNode nodes = xmlSoapRequest.SelectSingleNode("/soapenv:Envelope/soapenv:Body/queryResponse/result/records/sf:Account/sf:Name", man);

看来我做的一切正确。 我给它了织补名称空间。 但是节点总是以null结尾。

一个更简单的XPath语句最终起作用了。

XmlNode nodes = xmlSoapRequest.SelectSingleNode("//sf:Account/sf:Name", man);
