XPathNavigator in C#

I am using C#

I have instance of XPathNavigator

Now, what is required to me is that

If XPathNavigator.Select("//errors");

Has the values or has the errors than it return no of nodes.

If errors node has no values, then it should return 0.

If XPathNavigator.Select("//errors");

Has the values or it is 1

Can I have the Full XML file in String?

Can anyone check my code for this if it is correct?

especially saving of XPathNavigator to XML as string

I will save this string in database thereafter.

My Code is below:

      public int isErrorExists(XPathNavigator nav)
{

XPathNodeIterator iterator = nav.Select("//errors");

int cnt = 0;

while (iterator.MoveNext())
{
cnt++;
}

if (cnt!= 0)
{
            string strXML = nav.InnerXml;

            // Now save strXML in Database.
       }
      }

Guide me the best way and if my way is correct or not.

Also please correct my code if it is not.

Thanks in Advance

Kind Regards,

XmlDocument FDocument = new XmlDocument();
FDocument.Load(FFileName);
XmlNodeList FTemp = FDocument.GetElementsByTagName(NodeName);

if(FTemp.Count != 0)
{
string strXML = FDocument.Innerxml;
//Write to databse
}

Hi,

I will get XPathNavigator from Object.

Means I will use method which someone else has written will not written me XmlDocument but it will return me XPathNavigator

So, I want to check the values from XPathNavigator only.

Your Code is using XmlDocument, which is not my requirement.

There for I wrote method, where I will pass XPathNavigator in my function and do the processes.

public int isErrorExists(XPathNavigator nav)

I hope now you are more clear about my requirement and help me better.

Awaiting your reply
Thanks in Advance

public int isErrorExists(XPathNavigator nav)
{

XPathNodeIterator iterator = nav.Select("//errors");

if (iterator .Count != 0)
{
string strXML = nav.InnerXml;

// Now save strXML in Database.
}
}
