.net XMLWriter and attributes

Last Modified: 2013-11-07
I'm using the XmlWriter class in .Net 2.0.

I'm trying to write the following bit of XML (it's part of a larger thing, but this is where I'm having a problem).
<Worksheet ss:Name="Sheet1">

The code below yields the error:
System.ArgumentException: Invalid name character in 'ss:Name'. The ':' character, hexadecimal value 0x3A, cannot be included in a name.    

What do I need to do instead?

Private Sub XMLWorkSheetHeader(ByVal iResultNum As Int16, ByVal iRows As Int32, ByVal iColumns As Int16, ByRef W As XmlWriter)
            W.WriteAttributeString("ss:Name", "Sheet" & iResultNum)

You must add the proper declarations for the namespaces, otherwise this won't work.


And those namespaces would be URI's?  How do I know what URI to use?

I don't know what namespace you want to use. Probably something from microsoft's worksheets XML? You should use that namespace and declare it literally the same.

Otherwise (without a namespace) namespace prefixes (the parts before the colon) are illegal.

> How do I know what URI to use?

I don't know your application and I don't know why you want to write "ss:Name". Apparently that comes from somewhere else. Lookup that document and use the declaration from that document.


In the header of the document I see stuff like

Is that the kind of thing I should be using?


>>I don't know your application

I'm creating an XML spreadsheet from a data set and I want Excel to load it by default.

That's why I'm stuck on some funny-looking names -- I'm mimicking Excel's output.

Thanks for your help w/ this!
