使用xPath时是否可以忽略c#中的命名空间？

using System;
using System.Xml;
using System.Xml.XPath;

public class XPathExample
{
    public static void Main()
    {
        string xml = "<root><element>Value</element></root>";
        XmlDocument doc = new XmlDocument();
        doc.LoadXml(xml);

        XPathNavigator navigator = doc.CreateNavigator();
        XPathExpression expression = navigator.Compile("//element");
        XPathNodeIterator iterator = navigator.Select(expression);

        while (iterator.MoveNext())
        {
            Console.WriteLine(iterator.Current.Value);
        }
    }
}
