Are you using WCF or pre .NET 2.0 asmx web services?

Here are some links for web services, some with WCF and others with ASMX

Just use a parameter of type XmlElement to receive arbitrary XML, or return XmlElement to return arbitrary XML.

Hi try the following Code

Please write  following Code in Service.asmx page.....

public static string GetXmlString(string strFile)
    {
        // Load the xml file into XmlDocument object.
        XmlDocument xmlDoc = new XmlDocument();
        try
        {
            xmlDoc.Load(strFile);
        }
        catch (XmlException e)
        {

        }
        // Now create StringWriter object to get data from xml document.
        StringWriter sw = new StringWriter();
        XmlTextWriter xw = new XmlTextWriter(sw);
        xmlDoc.WriteTo(xw);
        return sw.ToString();
    }

Add Webreference to your Aspx Page..

then write following code in Aspx Page and Call the method here

first create object for the Service class;

protected void Page_Load(object sender, EventArgs e)

    {

    Service1 ser=new service1();       

   string XmlData = GetXmlString(Server.MapPath("Capabilities.xml"));
    DisplayXmlData(XmlData);
    }

public void DisplayXmlData(string s)  //convert String into Xml File.
    {
        XmlDocument getxmlfromstring = new XmlDocument();
        Response.ContentType = "text/xml";
        getxmlfromstring.LoadXml(s);
        getxmlfromstring.Save(MapPath("EmployeesNew.xml"));
        FileInfo file = new FileInfo(Server.MapPath("EmployeesNew.xml")); // full file path on disk
        Response.ClearContent(); // neded to clear previous (if any) written content
        Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
        Response.AddHeader("Content-Length", file.Length.ToString());
        Response.ContentType = "text/xml"; //RFC 3023
        //Response.TransmitFile(file.FullName);
        Response.WriteFile(file.FullName);
        Response.End();

    }

you can Send Xml files like this..

Hope It Will Helpful .....

This code is very bad, and demonstrates a lack of understanding of XML.

XML should never be treated as a string!
