Question

I have some stored proc.s that get data from DB.
I made some data access layers classes to get the data from the sql db
I have some Xml files that should be filled with this data.
I’m supposed to link between them using aspx pages.
Now, I want to know how can I read data at the aspx page from the xml file to send it to the server, and how can I write data from the db to the xml files.

I used to use json, but is there a method in which I can send and receive data without using json & just using XML ?

This is my XML File:

<allNews>
<news>
    <gNews>
        <flag>List of categories IDs this article linked to</flag>
        <title>news title goes here</title>
        <description>news description goes here</description>
        <date>news date goes here</date>
    </gNews>
</news> 

This is the function that retrieves a list from the database:

XDataContext XDB = new XDataContext();

    public getCategoryContentListResult GetCategoryContentList(int contentID)
    {
        return XDB.getCategoryContentList(contentID).SingleOrDefault<getCategoryContentListResult>();
    }

I want to know how can I connect these two files using aspx.

When I used Json I used to do this: [I read data from an ajax call at the javascript file)

        private getCategoryContentListResult GetCategoryList()
        {     
              int ContentID = int.parse(Request.QueryString["country"]);     
              int res = getCategoryContentListResult(ContentID);
              JsonResponse = JsonConvert.SerializeObject(res);
        }
        Response.Clear();
        Response.ContentType = "application/json";
        Response.ContentEncoding = System.Text.Encoding.UTF8;
        Response.Write(Request.QueryString["jsoncallback"] + "(" + JsonResponse + ");");
        Response.End(); 

Now I can’t use Json, I just have to use XML. SO is there some method to do it ?

Try modifying the below code accordingly

protected void Page_Load(object sender, EventArgs e)
    {
        XmlTextWriter writer = new XmlTextWriter("your.xml", System.Text.Encoding.UTF8);
        writer.WriteStartDocument(true);
        writer.Formatting = Formatting.Indented;
        writer.Indentation = 2;
        writer.WriteStartElement("AllNews");
        writer.WriteStartElement("News");
        //Loopthrough your dataset/datatable/Or datareader here
        //Call the CreateNode Method from here 
        //End of loop
        writer.WriteEndElement();
        writer.WriteEndElement();
        writer.WriteEndDocument();
        writer.Close();



    }

    private void createNode(string flag, string title, string desc, string date, XmlTextWriter writer)
    {
        writer.WriteStartElement("GNEWS");
        writer.WriteStartElement("flag");
        writer.WriteString(flag);
        writer.WriteEndElement();
        writer.WriteStartElement("title");
        writer.WriteString(title);
        writer.WriteEndElement();
        writer.WriteStartElement("description");
        writer.WriteString(desc);
        writer.WriteStartElement("date");
        writer.WriteString(date);
        writer.WriteEndElement();
        writer.WriteEndElement();
    }

Hope this will help.
