Question

I’m creating a xml-file for display in Excel using _di_IXMLDocument. But for some tags I get an unwanted extra (empty) xmlns attribute witch makes the file unreadable for Excel… This is what i do:

... _di_IXMLNode worksheet = workbook->AddChild('Worksheet'); worksheet->SetAttribute('ss:Name',Now().DateString()); ... 

and this is what comes out:

<Worksheet xmlns='' ss:Name='2008-12-11'> 

Where does xmlns come from? How do I get rid of it?

EDIT: Some more info: If I try to add a xmlns attribute to Worksheet myself, like this:

... _di_IXMLNode worksheet = workbook->AddChild('Worksheet'); worksheet->SetAttribute('xlmns','Foo'); worksheet->SetAttribute('ss:Name',Now().DateString()); ... 

Then the child nodes of ‘Worksheet’ all get the empty xmlns attributes instead!

<Worksheet xmlns='Foo' ss:Name='2008-12-11'>   <Table xmlns=''> 

Answer 1

Ok I had a look at this question. The trick was to create the child nodes and telling the what namespace they belong to, and then not to output it…

_di_IXMLNode worksheet = workbook->AddChild('Worksheet','workbooks-namespace',false); worksheet->SetAttribute('ss:Name',Now().DateString()); 

this produces the desired output:

<Worksheet ss:Name='2008-12-11'>
