Subject: hyphens in variable names

Hello,

I am new to Ruby and have an issue with a xmlsimple object resulting 
from a 3rd party webservice.

The xml has nodes that have hyphens (-) in the names. When I try to 
access various hashes using the object variables I get errors telling 
that the variable doesn't exists. I realize that the ruby syntax doesnot 
like hyphens in variable names, how do I get around this?

Example XML:

<object>
 <tree-lists>
   <tree-list>
   ...
   </tree-list>
   ...
 </tree-lists>
</object>

Example Ruby :

for tlist in object.tree-lists
 ...
end

Error would be:

NoMethodError in TreeController#importproject
undefined method `tree' for #<TreeLib::Record:0x39171e8>


Thanks in advance.
Paul
