how to add namespace to the xpath c# correctly?

i tried many different ways but it is keep saying: Data at the root level is invalid. Line 1, position 1. My question is: how can i add the namespace correctly?

if i delete the namespace from the xml, it works perfect but i cant do that because xml document is already created by somebody else.

This is my xml file:

<?xml version="1.0" encoding="utf-8"?>
<outputTree xmlns="http://www.ibm.com/software/analytics/spss/xml/oms" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.ibm.com/software/analytics/spss/xml/oms http://www.ibm.com/software/analytics/spss/xml/oms/spss-output-1.8.xsd">

c

private void GetXMLData()
{
    try
    {
        XmlDocument doc = new XmlDocument();
        doc.LoadXml(@"C:\Users\byilmaz\Desktop\SPSS_SITE\g.xml");

        XmlNamespaceManager nsmanager = new XmlNamespaceManager(doc.NameTable);
        nsmanager.AddNamespace("test", "http://www.ibm.com/software/analytics/spss/xml/oms");

        XmlNodeList errorNodes = doc.SelectNodes("/test:outputTree/", nsmanager);
        foreach (XmlNode errorNode in errorNodes)
        {
            //string errorCode = errorNode.Attributes["id"].Value;
            //string errorMessage = errorNode.InnerText;
        }

    }
    catch (Exception err)
    {
        throw (err);
    }
}

You should've used Load() method instead of LoadXml() to load XML from file :

doc.Load(@"C:\Users\byilmaz\Desktop\SPSS_SITE\g.xml");
