Subject: Design suggestion for translations/mappings from xml

Hi, i've got an xml file i'm parsing and creating objects from.

The xml is not named, nor formatted like my objects, so i need to define
a bunch of mappings/translations.

I'm looking for any design patterns or suggestions people might have to
elegantly solve this.

xml example:

<HotelDescriptiveContent CurrencyCode="USD" TimeZone="GMT;-06"
BrandCode="BV" HotelCode="517" HotelName="Americas Best Value Inn and
Suites - Downtown" Overwrite="true" UnitOfMeasureCode="1">
<HotelInfo WhenBuilt="2000" HotelStatus="Bookable" HotelStatusCode="1">
<CategoryCodes>
  <LocationCategory Code="3"></LocationCategory>
  <SegmentCategory Code="5"></SegmentCategory>
  <HotelCategory Code="20"></HotelCategory>
</CategoryCodes>
<Description>All the comforts of home conveniently...</Description>


object example:

class Hotel
  attr_accessor :property_name, :brand
end


There's a bunch of other classes and corresponding awkwardly named tags.

It'd be killer if i could do a to_xml as well as from.  But not
crucial...

Thanks for your help!
