Read an XML string into a dataset /datatable

Hello:  I rarely have to work with XML data, so bear with me.

I am getting an email message where in the body of the message there is the following string:

<?xml version="1.0" encoding="UTF-8"?><telemetry><esn>0-436701</esn><unixTimestamp>1284595879</unixTimestamp><hexPayload>0x02063F000000000000</hexPayload></telemetry>

I need to move the data in the XML string to a datatable / dataset so I can push it along to my database.  I've looked at XMLTextReaders and Linq to XML, but can't quite get it.

Suggestions?

Thanks

RW

You can read the values from the XML with code like the following
        Dim msgBody As String = "<?xml version=""1.0"" encoding=""UTF-8""?><telemetry><esn>0-436701</esn><unixTimestamp>1284595879</unixTimestamp><hexPayload>0x02063F000000000000</hexPayload></telemetry>"

        Dim xdoc = XDocument.Parse(msgBody)

        Dim esn As String = xdoc.<telemetry>.<esn>.Value
        Dim unixTimestamp As String = xdoc.<telemetry>.<unixTimestamp>.Value
        Dim hexPayload As String = xdoc.<telemetry>.<hexPayload>.Value

Try the following
            string myXml = "<xml version=\"1.0\" encoding=\"UTF-8\"><telemetry><esn>0-436701</esn><unixTimestamp>1284595879</unixTimestamp><hexPayload>0x02063F000000000000</hexPayload></telemetry>";
            myXml = myXml.Substring(myXml.IndexOf("<telemetry>"));
            XmlReader xmlReader = new XmlTextReader(new MemoryStream(ASCIIEncoding.Default.GetBytes(myXml)));
            DataSet ds = new DataSet();

            ds.ReadXml(xmlReader);

You can read the xml into a DataSet by invoking ReadXml(string) on the DataSet

http://msdn.microsoft.com/en-us/library/360dye2a.aspx


string strXML = "<?xml version="1.0" encoding="UTF-8"?><telemetry><esn>0-436701</esn><unixTimestamp>1284595879</unixTimestamp><hexPayload>0x02063F000000000000</hexPayload></telemetry>";

DataSet ds = new DataSet();
ds.ReadXml(strXML);

@Novice_Novice: If you try your example, It will give several errors (first of all on the creation of your strXML and secondly when you try to read it into a dataset. I do the same thing, only I solved already some problems
