I find that when I have data that is unpredictable (such as is the case here with respect to not knowing the potential nodes that might come up) its better to parse it from scratch.

I might be totally wrong but I am not sure if the XML you have described is well formed as is required.

Either way here is a hopefully readable but not the most efficient peice of code that achieves what you are aiming to do: 


use strict;
use warnings;


use Data::Dump qw( dump );


my $data = do{local $/;<DATA>};


my @people_educations;

while( $data =~ m/<person>(.*?)<\/person>/gis ) { 

    my $one_persons_info = $1;

    while( $one_persons_info =~ m/<education>(.*?)<\/education>/gis ) 
+{ 

    my $this_guys_education_details_string = $1 ;
    my %this_guys_education_details_hash        ;

    my @this_guys_education_sections            ;


    while( $this_guys_education_details_string =~ /<([^\/]*?)>/gis ) {

        push @this_guys_education_sections, $1 ;
        
    }

    foreach my $single_section ( @this_guys_education_sections ) { 

        if( $this_guys_education_details_string =~ /<$single_section>(
+.*?)<\/$single_section>/gis ) { 
        $this_guys_education_details_hash{ $single_section } = $1;
        
        }

    }

    push @people_educations, \%this_guys_education_details_hash;

    }

}


dump( \@people_educations );







__DATA__ 


<Person>
    <Address>
    <name>xxx</name>
    <mobile>xxx</mobile>
    </Address>
    <Education>
        <Degree>xxx</Degree>
         <Major>xxx</Major>
    </Education>
</Person>
    

<Person>
    <Address>

    <mobile>xxx</mobile>
    </Address>
    <Education>
        <Degree>xxx</Degree>
        <Minor>xxx</Minor>
        <Grade> ggg </Grade>
    </Education>
</Person>
    

<Person>

    </Education>

This will produce the following output: 

[
  { Degree => "xxx", Major => "xxx" },
  { Degree => "xxx", Grade => " ggg ", Minor => "xxx" },
  { Degree => "xxx" },
]
