Mapping extra XML attributes

[Matt Joiner]

I'm trying to marshal an XML element with arbitrary attributes. I want to decide when to omit certain attributes at runtime. To do this I'm assuming that some kind of map or slice of attributes is required but neither []xml.Attr nor any other intuitive types are handled for this purpose. Can anyone explain how to marshal optional attributes to an element at runtime?

I have a standing SO question for this too: http://stackoverflow.com/q/10828187/149482

Cheers

Have you tried ,omitempty on the attr?  I'm not positive that it will work, but I know the omitempty logic exists in xml.

I don't think omitempty is what I'm after.

You'll have to expand upon what you're looking for.

That omits attributes that are set to their zero value.
