上面的 XML 是標準的 VILT 創建事件 xml，我需要用適當的資料填充它。

問題是我能夠使用下面的代碼獲取“securityContent”元素，并且節點包含 4 個子元素的總數：

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

但是當我嘗試獲取另一個節點即“metaData”時，我得到 Count 0 并且獲取元素的方式完全相同，除了元素的路徑。

以下是我嘗試過但無法正常作業的示例代碼：

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;
}

任何人都知道上面的代碼有什么問題，我怎樣才能讓它作業？

uj5u.com熱心網友回復：

該bodyContent節點有一個默認命名空間，適用于它及其所有子節點。

您需要將它添加到NamespaceManager然后在 XPath 中使用它

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;
}
