Exporting XmlTextWriter output to string using vb.net

Question

I would like to export(convert) XmlTextWriter output data to string variable.

My code as follows :

        '' write data as xml
        Dim objX As New XmlTextWriter(Response.OutputStream, Encoding.UTF8)
        objX.WriteStartDocument()
        objX.WriteStartElement("Transaction")
        objX.WriteAttributeString("version", "1.0")
        objX.WriteElementString("id", "12")
        objX.WriteElementString("token", "4534gfdgdfhfst")


        objX.WriteEndElement()

        objX.WriteEndDocument()

        objX.Flush()

        objX.Close()
        Response.End()

the xml output am getting now is like this : 38824e4760a1b72f9bd95723a3bdffbd02280010.50en3475990rapids1 month rapidshare0.46587748175.136.184.1539/14/2012d7a1ff2200f9fe7b8b89d12fdc8be8f36293‌712eS. how to make it as xml tags

BTW, you shouldn't use XmlTextWriter, not since .NET 2.0. Use XmlWriter.Create like in Darin's example. — John Saunders

You have configured the XmlTextWriter to write directly to the Response.OutputStream. If you wanted to export it to a string variable you could use a StringWriter that will write to a StringBuilder.

Dim sb As New StringBuilder()
Using sw As New StringWriter(sb)
    Using writer = XmlWriter.Create(sw)
        ' write the XML to the writer here
    End Using
End Using
' At this stage the StringBuilder will contain the generated XML.

as an alternative you could write to a MemoryStream:

Using stream As New MemoryStream()
    Using writer = XmlWriter.Create(stream)
        ' write the XML to the writer here

        Dim xml As String = Encoding.UTF8.GetString(stream.ToArray())
        ' TODO: do something with the generated XML
    End Using
End Using

I have tried the first code and couldnt get the XML format, instead i got data only without tags.

Dim sb As New StringBuilder() Using sWriter As New StringWriter(sb) Using xWriter = XmlWriter.Create(sWriter) xWriter.WriteStartDocument() xWriter.WriteStartElement("Transaction") xWriter.WriteAttributeString("version", "1.0") xWriter.WriteElementString("id", "12") xWriter.WriteElementString("token", "4534gfdgdfhfst") xWriter.WriteEndElement() xWriter.WriteEndDocument() xWriter.Flush() xWriter.Close() Response.End() End Using End Using

What's wrong with the current code? What is the expected output? What is the actual output? Please don't use the comments section to post code snippets and XML data. Go ahead and update your original question to provide this information. Your comments are completely unredable.
