Rails - Jul 2006 - how to get builder 2.0 to escape attributes in rxml

I am using rxml to produce opml files and need to escape ampersands in 
the attributes.

builder 2.0 docs found at http://builder.rubyforge.org/ show the 
following

  xml = Builder::XmlMarkup.new
  xml.sample(:escaped=>"This&That",
:unescaped=>:"Here&There")
  xml.target!  =>
    <sample escaped="This&amp;That"
unescaped="Here&amp;There"/>

I tried to install and repeat this result, but attributes are not 
escaping

Here is the gem install and the attempt to test escaping attributes:

C:\rails>"c:\ruby\bin\ruby.exe" "c:\ruby\bin\gem" install
builder
--version 2.0

Attempting local installation of ''builder''
Local gem file not found: builder*.gem
Attempting remote installation of ''builder''
Successfully installed builder-2.0.0
Installing RDoc documentation for builder-2.0.0...

C:\rails>cd buildertest

C:\rails\buildertest>ruby script/console
Loading development environment.
>> xml = Builder::XmlMarkup.new
=> <inspect/>
>> xml.sample(:escaped=>"this & that")
=> "<inspect/><sample escaped=\"this &
that\"/>"
>> exit
Does anybody know what could be wrong?

Alex,
Alex,

Use builder''s << operator to append text without escaping markup.

Example
xml.<< ''This&That''

See also my blog post on using this in rxml templates:

Hope this helps,
Zack

Thanks for the reponse Zack, but my problem is the opposite.  I need 
Builder to escape the markup and it''s not doing it for some reason.

When I use buidler

this is what I get

C:\rails\buildertest>ruby script/console
Loading development environment.
>> xml = Builder::XmlMarkup.new
=> <inspect/>
>> xml.sample(:escaped=>"this & that")
=> "<inspect/><sample escaped=\"this &
that\"/>"
>> exit
If you look at the markup you can see that what is supposed to be 
escaped is not.

I am running builder 2.0 and the specs say that it should escape 
attributes, but for some reason it doesn''t seem to be working.

Any idea what might be wrong?
