Rails - Apr 2009 - XML Builder - problems with serialized ruby

Hi,

I''m using the Builder gem to transform an array/hash that contains
serialized ruby. Builder''s to_xs method seems to mangle serialized
ruby though. I can get around this by encoding/decoding with base 64,
but that doesn''t seem like a good path to follow.

Builder is using this code for escaping:

Any ideas on how to modify that, so serialized ruby will be escaped
properly?

Thanks,
Matt
