Having Trouble With XMLWriter

.NET
1

Hi,
I’m trying to create a simple xml structure using the XMLWriter in visual basic for the purpose of creating an html page based on user input.

Here’s an example of what I’ve got so far:


        Dim writer As XmlTextWriter

        writer.WriteStartElement("main")
        writer.WriteStartElement("test1")
        writer.WriteStartElement("test2")
        writer.WriteEndElement()
        writer.WriteEndElement()
        writer.WriteEndElement()
MsgBox(writer)

I’m getting the following error:
Nullreferenceexception was unhandled
Object reference not set to an instance of an object.

Can someone help me get past this please?

Also I guess I should ask, am I doing this the best way, any other suggestions are welcome, but I would also like to learn how to do it this way as (To my knowledge) this way doesn’t require you to create a whole document.

Thanks.

Steve

Wouldn’t you need to save it to a file, before using it?



dim writer as XMLTextWriter
writer = new XMLTextWriter(Server.MapPath("Data.xml"), nothing)

I’m sure that’s how you are supposto use the TextWriter object. Because you would need to write it, and then use a reading object to show the xml file.

EDIT: You might need to use the: XMLDocument object instead.

Using the XmlTextWriter is fine, but you need to set the output. To a FileStreamWriter or Outputstream.

Also do not forget:
writer.WriteStartDocument() and WriteEndDocument()

Here’s what I’ve got so far, but I’m getting no output:


        Dim writer As XmlTextWriter
        writer = New XmlTextWriter("C:\\Documents and Settings\\Steve\\Desktop\\Visual Basic Stuff\\image gallery creator test\\images\	est.xml", Nothing)

        writer.WriteStartDocument()
        writer.WriteStartElement("main")
        writer.WriteStartElement("test1")
        writer.WriteStartElement("test2")
        writer.WriteEndElement()
        writer.WriteEndElement()
        writer.WriteEndElement()
        writer.WriteEndDocument()

I don’t think I’ve fully understood your advice.

I don’t see why I can’t just “tostring” the writer and see/use the output
