ROXML versus simple to_xml

How they differ?

Does the to_xml method of the classes array/hash/object is based on
ROXML lib?
As I see in http://roxml.rubyforge.org/#quickstart, roxml needs we
define the class (class Book in the guide) before to convert a object
to xml. Moreover, the method to_xml (when not using “include ROXML”)
just accepts any existing object, what is much suitable.

I need to compare and tranfer some records between local and remote
systems periodically. The tables (mysql) has simple varchar/integer/
date/decimal types.
Which type of xml mapping is recommended to achieve this task? ROXML
or pure to_xml method?

Thank you!

It’s also pretty handy for parsing incoming xml.

Sorry my bad english. Im not sure if I understood your answer. My model is activerecord based, but has just simple attributes (strings, integers, dates). Do you mean I dont need ROXML in this simple case? The non-
roxml
to_xml/from_xml methods can do the job?

I would have though to_xml/from_xml would be quite enough here.

I will try it.

Anyway, What are the “more general problem” you said?

Just the more general case of mapping xml fragments to objects.
