I am using activeresource 2.3.3

I was using ActiveResource today and it seemed to be choking on  
namespaced xml, like this:  
media:group

on line 1057 it erred with “Wrong constant name Media:group”

first i tried on line 1048  
name = name.to\_s.gsub(’:’,’/’)

which started failing in the same place but with: “Wrong constant name  
Media::Group”

so I added this on line 1048:  
name = name.to\_s.gsub(’:’,’\_’)

which got everything working again, but this seems a little fragile to  
me. Monkey patching a gem isn’t exactly the most ideal solution. Does  
anyone have a recommendation as to how to properly fix this? How am I  
“doing it wrong” as they say.
