I have dowunloaded the xml-simple-1.0.12.gem .

I used xml-simple to requie .  
require ‘xml-simple’ But it doesn’t work

Then I have given like this It works,  
require ‘xmlsimple’

My question is that,

How do i know it should be xmlsimple. But the gem file is  
xml-simple-1.0.12.gem

What happens when you run this command:

$ gem list --local

In summary, you don’t. Read the documentation/examples, or look at what  
files the gem contains and make an educated guess as to the one which  
you should require.

This seems to be one area (of many) where Perl’s CPAN is superior. The  
naming is consistent. The package xml-simple-x.xx will contain the  
module XML::Simple. This will physically exist in the file XML/  
Simple.pm. In your code you know to ‘use XML::Simple;’

Of course, with Perl’s austere naming conventions, you tend not to get  
colorful package names like Cucumber, for better or worse. (Though I  
just noticed a perl port of it with the module name Test::Cucumber  
[Test-Cucumber-0.001 - Perl extension for "Natural Language" test development - metacpan.org](http://search.cpan.org/dist/Test-Cucumber-0.001/))
