Hello, It's me again! :) I have changed the data structure just a little bit to something alittle bit more complex, but not too much! Here is my updated struc:

my $VAR2 = {
        'SuccessfulTests' => [
            {
                'Test' => {
                    'id' => '1',
                    'name' => 'toto'
                }
            },
            {
                'Test' => {
                    'id' => '1',
                    'name' => 'titi'
                }
            }
        ],
        
        'FailedTests' => [
            {
                'FailedTest' => {
                        'id' => '1',
                        'name' => 'tutu',
                        'svgs' => [
                                    {
                                        'svg' => '\tutu_1.svg'
                                    }
                                ]
                    }
            },
            {
                'FailedTest' => {
                        'id' => '1',
                        'name' => 'tete',
                        'svgs' => [
                                    {
                                        'svg' => '\tete_1.svg'
                                    },
                                    {
                                        'svg' => '\tete_2.svg'
                                    }
                                ]
                    }
            }
        ]
};

What I would like to get is something like this:

<?xml version="1.0" encoding="utf-8"?>
<TestRun>
  <SuccessfulTests> 
    <Test name="toto"/> 
  </SuccessfulTests> 
 <SuccessfulTests> 
    <Test name="titi"/> 
  </SuccessfulTests>  
  <FailedTests> 
    <Test name="tutu"/>
    <svgs>
        <svg>\tutu_1.svg</svg>        
    </svgs>    
  </FailedTests> 
    <FailedTests> 
    <Test name="tete"/> 
    <svgs>
        <svg>\tete_1.svg</svg>    
        <svg>\tete_2.svg</svg>    
    </svgs>    
  </FailedTests>   
  </TestRun>

I have tried to use 'GroupTags' to do this but unfortunately I have not succeded. Any help would be appreciated, again :) Thx!
