Hi all,  
after spending a long night trying to track down some unexpected spec  
failures in my app I came to the conclusion that the reason was aws-s3  
gem, which probably monkey patches XmlSimple class and changes its  
behaviour so that xml\_in method won’t honor passed options anymore.  
Here is a simple spec file to prove it… uncomment line 4 to make it  
fail.

require ‘rubygems’  
require ‘spec’  
require ‘xmlsimple’

# require ‘aws/s3’

module XmlSimpleHelper  
def xml\_sample  
%q(  
  
Ciao  
Hello  
  
)  
end  
end

describe XmlSimple do  
include XmlSimpleHelper  
it ‘should remove root tag by default’ do  
expected = {‘greeting’ =\> [“Ciao”, “Hello”]}  
XmlSimple.xml\_in(xml\_sample).should == expected  
end

it ‘should keep root tag when asked’ do  
options = {‘KeepRoot’ =\> true}  
expected = {‘greetings’ =\> [{‘greeting’ =\> [“Ciao”, “Hello”]}]}  
XmlSimple.xml\_in(xml\_sample, options).should == expected  
end

it ‘should force to array when asked’ do  
options = {‘ForceArray’ =\> true}  
expected = {‘greeting’ =\> [“Ciao”, “Hello”]}  
XmlSimple.xml\_in(xml\_sample, options).should == expected  
end  
end

All gems were freshly updated… I haven’l looked at aws-s3 code yet,  
I will do later, in the meanwhile I’d like to know other people  
opinion, if this is some kind of bug in the gem or what…

TIA

Andrea L.

Again, the aws-s3 gem keeps biting my hand:

require ‘rubygems’  
require ‘spec’  
require ‘xmlsimple’  
require ‘aws/s3’ # remove to test pass

def xml  
%q(10.99)  
end

def expected  
{“content”=\>“10.99”, “currency”=\>“USD”}  
end

describe XmlSimple do  
it ‘should return expected content’ do  
data = XmlSimple.xml\_in(xml, ‘keeproot’ =\> false)  
data.should == expected  
end  
end
