Namespace problems

[David Thielen]

Hi;

I am creating an XmlDocument (.net 2.0) and then saving it. I need the final
xml file to look as follows (SpreadsheetML schema - I have no control over
it):

<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:dt="uuid:C2F41010-65B3-11d1-A29F-00AA00C14882"
xmlns:ss="schemas-microsoft-com:office:spreadsheet">
<CustomDocumentProperties xmlns="urn:schemas-microsoft-com:office:office">
<WindwardReports dt:dt="string">Version: 4.0.12</WindwardReports>
</CustomDocumentProperties>
<Styles>
<Style ss:ID="Default" ss:Name="Normal">
<Alignment ss:WrapText="1" ss:Horizontal="Left" ss:Vertical="Bottom"/>
</Style>
</Styles>
...

To create a namespace (this is my best guess based on the docs & googling):
element.SetAttribute(prefix.length() == 0 ? "xmlns" : ("xmlns:" + prefix),
url);
nameMgr.AddNamespace(prefix, url);
// when I create XmlDocument I also call:
nameMgr = new System.Xml.XmlNamespaceManager(xmlDoc.get_NameTabl e());

But what I am getting is:
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:dt="uuid:C2F41010-65B3-11d1-A29F-00AA00C14882"
xmlns:ss="schemas-microsoft-com:office:spreadsheet">
<CustomDocumentProperties xmlns="urn:schemas-microsoft-com:office:office">
<WindwardReports dt="string" xmlns="">Version: 4.0.12</WindwardReports>
</CustomDocumentProperties>
<Styles xmlns="urn:schemas-microsoft-com:office:spreadsheet">
<Style ID="Default" Name="Normal" xmlns="">
<Alignment WrapText="1" Horizontal="Left" Vertical="Bottom" />
</Style>
</Styles>
...

What am I doing wrong?

Hello!

You usually don't have to care about the xmlns-Attributes. Just use the
correct methods wich allow you to specify a prefix, localName, namespace
and value for an attribute.

The XmlDocument will write the necessary xmlns:ss="schemas.." for you.
If you want, you may also drop the prefix and have one created
automatically (but it may not look nice to humans).
