ruby on rails xml builder question

Anybody know how to produce an xml element like this in rails using xml Builder?

<image:loc>开发者_Go百科;http://example.com/image.jpg</image:loc>

xml.image :loc http://example.com/image.jpg

Is supposed to work but doesn't.

You're pretty close, but the correct syntax is:

xml.image :loc, "http://example.com/image.jpg"
