layout for XML builder in rails 3 -


i create general layout file xml response. example wrap general part of rss in layout , leave content generated in corresponding view file.

for example, 

# in layout/rss.xml.builder xml.instruct! ...... # other general stuff rss    yield  # in items/show.xml.builder xml.item ......

so item show view no need worry rss wrappings.

however yield not working , layout rendered, view returned nothing.

please help.

try:

xml.instruct!   xml << yield
