I'm trying to parse an XML like the one below with XML::Simple. I'm not sure what loop I should be using, I thought about using a for loop but it will only parse all the <level> but not the <study> (<study> is the lowest level but can appear at any level in the XML as you can see) 
for my $level1_ref (@{$report_config->{"levels"}->{"level"}}) {
   print...
}

Here's the XML 

<config>
    <levels name="a" target="29.6">
        <level name="b"    weight="50" target="35.1">    
            <study id="32" name="i"    weight="30" />
            <study id="36" name="j"    weight="70" />
        </level>
        
        <study id="37" name="k" weight="15" />
        
        <level name="c" weight="13" target="22.1">    
            <level name="d" weight="69.2">    
                <level name="e"    weight="44.4">    
                    <study id="34" name="l"    weight="50" />
                    <study id="27" name="m"    weight="50" />
                </level>
                <level name="f"    weight="55.6">

        </level>
    </levels>
