Rails - Dec 2006 - rexml help

Hi I am creating a hash as detailed below

hPhotoDetails = {
 :photoId =>
pDoc.elements[''/rsp/photo''].attributes.get_attribute("id").value,
 :title => pDoc.elements[''/rsp/photo/title''].text,
 :description =>
pDoc.elements[''/rsp/photo/descripton''].text,
}

if the element /rsp/photo/descripton == <description/> or does not exist
an error is thrown.

Is there a way to get it to add nil if it does not exist without
breaking out of the hash creation?

Thanks
jon

def de_nil(q)
   return q if q
   require ''ostruct''
   return OpenStruct(:text => '''')
end

That''s the "Null Object Refactor" in a nutshell. Google for
all my
terms because I might have the details wrong.
