Xml Open and Closing

I am using the xmltextwriter and having issues with opening tags not showing if the field is blank

here is the start of my code

Code:

---

  Dim strFilePath As String = Server.MapPath("../test.xml")
        Dim utf8 As Encoding = New UTF8Encoding(False)
        Dim objWriter As XmlTextWriter = New XmlTextWriter(strFilePath, New UTF8Encoding(False))

        ' start writing the XML document
        objWriter.WriteStartDocument()

     
        Try
            conn.Open()
            myreader = cmd.ExecuteReader

       
            objWriter.WriteStartElement("testfile")

            While myreader.Read

                ' output the first "product" element
                objWriter.WriteStartElement("product", Nothing)
                objWriter.WriteElementString("Id", myreader("rvid").ToString)
                objWriter.WriteElementString("Class", myreader("RVClass").ToString)
                objWriter.WriteElementString("Manu", myreader("rvmanu").ToString)
                objWriter.WriteElementString("Model", myreader("rvmake") & " " & myreader("rvmodel"))
                objWriter.WriteElementString("Year", myreader("rvyear").ToString)
                objWriter.WriteElementString("Price", myreader("rvcashprice").ToString)
                objWriter.WriteElementString("NU", myreader("rvnu").ToString)
                objWriter.WriteElementString("SCapacity", myreader("rvcapacity").ToString)
                objWriter.WriteElementString("Fuel", myreader("rvfuel").ToString)
                objWriter.WriteElementString("Length", myreader("rvlenft").ToString)
                objWriter.WriteElementString("Air", myreader("rvair").ToString)
                objWriter.WriteElementString("Awnings", myreader("rvawnings").ToString)

Thats not all of it.. but what happens is if it is blank value

Then i get this, as you see fuel has no opening tags, and the company i am supplying to needs these.

<Price>0.0000</Price>
<NU>U</NU>
<SCapacity>0</SCapacity>
<Fuel />
<Length>0</Length>


What can i do to make this work how i want? I though the .tostring woudl fix it but it didnt.

Thanks

Hey,

Code:

---

<Fuel />

Is perfectly valid XML. It would suggest to me, that:

Code:

---

myreader("rvfuel").ToString

---

Is returning an empty string. Can you step into your code with the debugger to validate that this is what is happening?

Yeah i am pretty sure its returning empty string without looking.
Thats what i saw in database.

Maybe there feed doesnt like it or they dont know better :)

Sounds like they are probably manually parsing the XML, (as opposed to using an XML parser of some kind) which quite frankly surprises and disappoints me. I'd talk to them, explain that what you are producing is not only valid XML, but universally accepted and try to find out why they won't accept it on their end.
