Above XML is standard VILT Create Event xml and I need to populate it with proper data.

The issue is I am able to get "securityContent" element using below code and node holds total count of child elements that is 4:

var node = xmlDoc.SelectNodes("/serv:message/header/securityContext/*", GetNameSpace(xmlDoc.NameTable));

But when I try to get another node i.e. "metaData" then I get Count 0 and way to getting element is exactly same except the path to the element.

Below is sample code that I've tried but not working:

static void Main(string[] args)
{
    var xmlPathh = @"C:\Users\SKMEENA\Desktop\VILT.xml";// this holds above xml
    XmlDocument xmlDoc = new XmlDocument();
    xmlDoc.Load(xmlPathh);

    var node = xmlDoc.SelectNodes("/serv:message/header/securityContext/*", GetNameSpace(xmlDoc.NameTable));

    var member = xmlDoc.SelectNodes("/serv:message/body/bodyContent/metaData/*", GetNameSpace(xmlDoc.NameTable));
}

static XmlNamespaceManager GetNameSpace(XmlNameTable objNameTable)
{
    XmlNamespaceManager objNsManager =new XmlNamespaceManager(objNameTable);
    objNsManager.AddNamespace("serv", "http://www.webex.com/schemas/2002/06/service");
    objNsManager.AddNamespace("ns1", "http://www.webex.com/schemas/2002/06/service/site");
    return objNsManager;
}

Anybody has any idea what is wrong with above code and how can I make it working?

CodePudding user response：

The bodyContent node has a default namespace which applies to it and all its children.

You need to add it to the NamespaceManager and then use it in the XPath

var member = xmlDoc.SelectSingleNode("/serv:message/body/body:bodyContent/body:metaData", GetNameSpace(xmlDoc.NameTable));
member.OuterXml.Dump();

static XmlNamespaceManager GetNameSpace(XmlNameTable objNameTable)
{
    XmlNamespaceManager objNsManager =new XmlNamespaceManager(objNameTable);
    objNsManager.AddNamespace("serv", "http://www.webex.com/schemas/2002/06/service");
    objNsManager.AddNamespace("ns1", "http://www.webex.com/schemas/2002/06/service/site");
    objNsManager.AddNamespace("body", "http://www.webex.com/schemas/2002/06/service/training");
    objNsManager.AddNamespace("sess","http://www.webex.com/schemas/2002/06/session");
    return objNsManager;
}
