Data Set to text file.

[{FPP}]

Hi, i use this code

 DataSet dsPubs = new DataSet();
            System.Xml.XmlDocument xdcDOC = new System.Xml.XmlDocument();
            // Read in XML from file
            dsPubs.ReadXml("http://www.nytimes.com/services/xml/rss/nyt/International.xml");
            // Bind DataSet to Data Grid
            grdData.DataMember = "item";
            grdData.DataSource = dsPubs;
            tmrDisplay.Enabled = true;

To populate a dataset with the RSS info...How could i on a click of a button save this to text file?

Like this is what i should look like:

Title: The title colum

Description - Description colum

Thanks
