如何使用c＃.net更新soap xml文件中的SOAP xml元素值？我的文件如下：

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
   <soap:Header>
      <Action  xmlns="http://www.w3.org/2005/08/addressing">http://extn.ssac.ee.sim.dsh.cms.hhs.gov/SsaCompositePortType/VerifySSAResponse</Action>
      <MessageID xmlns="http://www.w3.org/2005/08/addressing">urn:uuid:27f0af81-0da7-441f-83a7-fb2beaf30664</MessageID>
      <RelatesTo xmlns="http://www.w3.org/2005/08/addressing">uuid:e8dcd685-cb86-400a-8059-dcad985a7ea7</RelatesTo>
   </soap:Header>
   <soap:Body>
      <exch:SSACompositeResponse xmlns:exch="http://ssac.ee.sim.dsh.cms.hhs.gov">
         <ssac:SSACompositeIndividualResponse xmlns:ssac="http://extn.ssac.ee.sim.dsh.cms.hhs.gov">
            <ssac:ResponseMetadata>
               <ssac:ResponseCode>HS000000</ssac:ResponseCode>
              <ssac:ResponseDescriptionText>Success</ssac:ResponseDescriptionText>
            </ssac:ResponseMetadata>
          <ssac:PersonSSNIdentification>199123051</ssac:PersonSSNIdentification>
        <ssac:SSAResponse>
           <ssac:SSNVerificationIndicator>true</ssac:SSNVerificationIndicator>
           <ssac:DeathConfirmationCode>Unconfirmed</ssac:DeathConfirmationCode>
           <nc:PersonUSCitizenIndicator xmlns:nc="http://niem.gov/niem/niem-core/2.0">true</nc:PersonUSCitizenIndicator>
           <ssac:PersonIncarcerationInformationIndicator>false</ssac:PersonIncarcerationInformationIndicator>
           <ssac:SSATitleIIAnnualIncomeInformationIndicator>false</ssac:SSATitleIIAnnualIncomeInformationIndicator>
           <ssac:SSATitleIIMonthlyIncomeInformationIndicator>false</ssac:SSATitleIIMonthlyIncomeInformationIndicator>
           <ssac:SSAQuartersOfCoverageInformationIndicator>false</ssac:SSAQuartersOfCoverageInformationIndicator>
        </ssac:SSAResponse>
     </ssac:SSACompositeIndividualResponse>
  </exch:SSACompositeResponse>

这里我想更新ssac：PersonSSNIdentification（199123051）的值为9876543210？

                XmlNamespaceManager xnm;
                xnm = new XmlNamespaceManager(new NameTable());
                xnm.AddNamespace("soap", "http://www.w3.org/2003/05/soap-envelope");
                var xmlDoc = new XmlDocument();
                xmlDoc.Load(newSSAPathName);
                XmlNodeList aNodes = xmlDoc.SelectNodes("/Envelope/Body/SSACompositeResponse/SSACompositeIndividualResponse");
                foreach (XmlNode aNode in aNodes)
                {  var innerXmlNode = aNode.SelectSingleNode("/PersonSSNIdentification");
                    if (innerXmlNode != null)
                    {  innerXmlNode.Value = lstSsn[0];
                    }
                }
                xmlDoc.Save(newSSAPathName);

但这不起作用......有什么办法......

Answer 1

我建议使用LINQ to XML而不是较旧的XmlDocument API执行此操作。

首先，将您的XML加载到XDocument：

        var doc = XDocument.Load(newSSAPathName);

然后，为XML中的每个命名空间定义XNamespace：

        var soap = (XNamespace)"http://www.w3.org/2003/05/soap-envelope";
        var exch = (XNamespace)"http://ssac.ee.sim.dsh.cms.hhs.gov";
        var ssac = (XNamespace)"http://extn.ssac.ee.sim.dsh.cms.hhs.gov";

现在使用所需的完全限定名称查询XML层次结构中所需深度的所有elements：

        var ssnIds = doc.Elements(soap + "Envelope")
            .Elements(soap + "Body")
            .Elements(exch + "SSACompositeResponse")
            .Elements(ssac + "SSACompositeIndividualResponse")
            .Elements(ssac + "PersonSSNIdentification");

最后，更改相应的元素值：

        foreach (var ssnId in ssnIds)
            if (ssnId.Value == "199123051")
                ssnId.Value = "9876543210";

或者，如果您确实想要使用XPATH查询，则需要使用所有3个名称空间填充XmlNamespaceManager。 XPathSelectElements(XNode, String, IXmlNamespaceResolver) using (var reader = XmlReader.Create(newSSAPathName)) { var doc = XDocument.Load(reader); // Set up a namespaceManager as described in https://msdn.microsoft.com/en-us/library/bb351355%28v=vs.110%29.aspx var nameTable = reader.NameTable; var namespaceManager = new XmlNamespaceManager(nameTable); namespaceManager.AddNamespace("soap", "http://www.w3.org/2003/05/soap-envelope"); namespaceManager.AddNamespace("exch", "http://ssac.ee.sim.dsh.cms.hhs.gov"); namespaceManager.AddNamespace("ssac", "http://extn.ssac.ee.sim.dsh.cms.hhs.gov"); var ssnIds = doc.XPathSelectElements("soap:Envelope/soap:Body/exch:SSACompositeResponse/ssac:SSACompositeIndividualResponse/ssac:PersonSSNIdentification", namespaceManager); foreach (var ssnId in ssnIds) if (ssnId.Value == "199123051") ssnId.Value = "9876543210"; }显示了如何执行此操作。然后使用您在XPATH查询中为每个命名空间选择的前缀：

using System.Xml.XPath;

请务必在文件开头XPathSelectElements XmlDocument，因为var xmlDoc = new XmlDocument(); xmlDoc.Load(newSSAPathName); var nameTable = xmlDoc.NameTable; var namespaceManager = new XmlNamespaceManager(nameTable); namespaceManager.AddNamespace("soap", "http://www.w3.org/2003/05/soap-envelope"); namespaceManager.AddNamespace("exch", "http://ssac.ee.sim.dsh.cms.hhs.gov"); namespaceManager.AddNamespace("ssac", "http://extn.ssac.ee.sim.dsh.cms.hhs.gov"); var ssnIds = xmlDoc.SelectNodes("soap:Envelope/soap:Body/exch:SSACompositeResponse/ssac:SSACompositeIndividualResponse/ssac:PersonSSNIdentification", namespaceManager); foreach (XmlNode ssnId in ssnIds) if (ssnId.InnerText == "199123051") ssnId.InnerText = "9876543210";是一种扩展方法。

<强>更新

使用Invalid Argument，等效的XPATH查询是：

UPDATE
SP_Table INNER JOIN Access_Table on SP_Table.ID1 = Access_Table.ID1
SET 
SP_Table.Field1 = Access_Table.Field1,
SP_Table.Field2 = Access_Table.Field2,
--etc...
WHERE 
(SP_Table.Field1 <> Access_Table.Field1 AND SP_Table.ID1 = Access_Table.ID1)
OR
(SP_Table.Field2 <> Access_Table.Field2 AND SP_Table.ID1 = Access_Table.ID1)
OR
--etc...
;
