Question

I have been testing my code to save into an XML file locally and it is working fine. However i have just uploaded it to my server and it is not working. I changed the path to the path of the xml file but still no luck. This is my local code…

public void AddNodeToXMLFile(string XmlFilePath, string NodeNameToAddTo)
    {
        //create new instance of XmlDocument
        XmlDocument doc = new XmlDocument();

        //load from file
        doc.Load(XmlFilePath);

        //create main node
        XmlNode node = doc.CreateNode(XmlNodeType.Element, "Level", null);

        //create the nodes first child
        XmlNode mapname = doc.CreateElement("map");
        //set the value
        mapname.InnerText = mapsave.Value;

        // add childes to father
        node.AppendChild(mapname);

        // find the node we want to add the new node to
        XmlNodeList l = doc.GetElementsByTagName(NodeNameToAddTo);
        // append the new node
        l[0].AppendChild(node);
        // save the file
        doc.Save(XmlFilePath);
    }

protected void btnSave_Click(object sender, EventArgs e)
    {
        if (mapsave.Value.ToString() == "")
        {
            lblResult.Text = lblError.Value;
        }
        else
        {
            AddNodeToXMLFile("C:\\Users\\Glen.Robson\\Documents\\Visual Studio 2010\\Projects\\Project1\\Project1\\Scripts\\UserMaps.xml", "TileMaps");
        }

    }

So when i uploaded to the server i changed the path of AddNodeToXMLFile() to:

"http://www.mydomain.com/Scripts/UserMaps.xml"

But this does not work… Can anyone tell me what the file path should be?

Answer 1

You cannot change the path to a URL… the code on the server still needs to know the physical path to the file on the server. It cannot work out where the file is based on a URL.

Why don’t you use an application specific path…

AddNodeToXMLFile(VirtualPathUtility.ToAbsolute("~/Scripts/UserMaps.xml"),"TileMaps");

Then in your function, you need to “map” the virtual path into an actual physical path on the server…

public void AddNodeToXMLFile(string XmlFilePath, string NodeNameToAddTo)
{
   XmlFilePath = Server.MapPath(XmlFilePath);
   ...

Also, you need to make sure that permissions are setup on the server correctly – meaning that the process that the ASP.NET application is running on IIS with, has the ability to write to the directly
