As we all need more free stuff that does the same\*, here’s another  
XML serialization library:

XMLable 0.1.1

Some copy-paste from the docs:

Simple, and I mean really-simple, non-secure way to convert ruby  
objects to/from XML data.  
(ok, right now is really simple and maybe not really non-secure, but  
it doesn‘t mean it can‘t be a bit more “secure” in the future :-P)  
Just make sure that your class includes the XMLable module and the  
constructor has only one parameter: a Hash with String keys for each  
attribute you want to setup on initialization.  
You can also use the utility function init\_attributes\_with\_opts to  
initialize the attributes (check the doc)  
Oh, also, XMLable depends on REXML, so make sure you require  
somewhere in your code ‘rexml/document’.

Now, for the fun, some irb tricks:

irb(main):001:0\> require ‘xmlable’  
=\> true  
irb(main):002:0\> require ‘rexml/document’  
=\> true  
irb(main):003:0\> [1,2,3].to\_xml  
=\> … \</\>  
irb(main):004:0\> [1,2,3].to\_xml.to\_s  
=\> “12\</  
ritem\>3”  
irb(main):005:0\> [1,Time.now,nil,[“wow”,:nice]].to\_xml.to\_s  
=\> "11187725687.81283\<ritem rclass=‘NilClass’/

> wow\</  
> ritem\>nice"  
> irb(main):006:0\> data = [1,nil,“lalala”].to\_xml  
> =\> … \</\>  
> irb(main):007:0\> Array.from\_xml(data)  
> =\> [1, nil, “lalala”]  
> irb(main):008:0\> Array.from\_xml(data.to\_s)  
> =\> [1, nil, “lalala”]  
> irb(main):009:0\> data = {:hey =\> “thisisfun”, [“right”,“?”] =\> nil}  
> =\> {[“right”, “?”]=\>nil, :hey=\>“thisisfun”}  
> irb(main):010:0\> Hash.from\_xml(data.to\_xml)

> irb(main):017:4\> end  
> irb(main):018:3\> end

- I just was lazy searching for some library, and because I was  
bored, I ended up writing my own library… 😛

Enjoy!
