how do I access xml attribute details using XML::Simple and/or XML::Mini::Document or XML::LibXML ?

I am trying to understand and compare 4 ways in which I could use perl cpan xml modules to extract some info from a bunch of given XML files.

I have written some proof of concept code using XML::XPath and am left wondering how this "simple" task would be solved by using on of the other XML modules? I am a beginner in some ways and learn best by observing a problem and then copying that sample and modyfying it to my needs.

my perl XML::XPath code
#!/usr/bin/perl 
#file: show-barcodes-with-XML-XPath.pl
#!/usr/bin/perl

use XML::XPath; 
 
my $file = "00000002.TIF.xml"; 
my $xp = XML::XPath->new(filename => $file); 
my $barcode_code39 = $xp->find('/barcodes/source/index/symbol[@type="C
+ODE-39"]/data');
my $barcode_qrcode = $xp->find('/barcodes/source/index/symbol[@type="Q
+R-Code"]/data');

$barcode_code39 = substr($barcode_code39, 0, 10);

print ("Code 39: ", $barcode_code39, "\n");
print ("QR-Code: ", $barcode_qrcode, "\n");

#print ("processed: " . $file . "\n");



#file: 00000002.TIF.xml
<barcodes xmlns='http://zbar.sourceforge.net/2008/barcode'>
<source href='00000002.TIF'>
<index num='0'>
<symbol type='QR-Code' quality='1'><data><![CDATA[0037000249]]></data>
+</symbol>
<symbol type='CODE-39' quality='102'><data><![CDATA[0037000249P]]></da
+ta></symbol>
</index>
</source>
</barcodes>

How would I employ XML::Simple to do the "same" thing ?

And how would I write the same thing using XML::Mini::Document ?

And lastly how would I write the same thing using XML::LibXML ?

Thanks for any insights into how this would be done using one of the above
