Hello,

I am running into a road block with xmlwriter in that I am writing an xml file that has to conform to a certain standard for a specific line has a format I can not seem to output correctly using .WriteStartElement() and .WriteAttributeString().

I sure it is a brainfart on my part, but here is the equivalent line I need to output.

<toc:file toc:URI="file:///filename.ice" />

I get that I need .WriteStartElement("toc","file","Insert something"); to get the first part.
The second part, I can not figure out how to get the "toc:" before the "URI="file//..." part.

Any thoughts on what I am missing here?

Thanks.

The toc: prefix will be associated with an XML namespace URI - the "Insert something" part of your WriteStartElement call. You need to pass the same URI to the WriteAttributeString method:

C#

const string TocNamespaceUri = "...";

writer.WriteStartElement("toc", "file", TocNamespaceUri);
writer.WriteAttributeString("URI", TocNamespaceUri, "file:///filename.ice");
writer.WriteEndElement();

This will give you a node which looks like:

XML

<toc:file toc:URI="file:///filename.ice" xmlns:toc="..." />

The namespace URI will need to be a specific value - you'll need to check the specification for the file to find out what that is.
