Getting xml file display as xml when using render :text

Hi,

I have a problem when I do a

fd = File.open("test","rb")
render :text fd.read

I the "test" file contains xml

<animal>dog</animal>
<animal>cat</animal>

The output is shown as "dog cat" how do I get the xml shown as is with
the animal tag also shown?

THanks,
Sudhi
