Hi to all perlmonks users, and thanks all and in particular to whom will waste some minutes with my silly questions

I'm really losing my mind with a file formatted like this:

This file contains 24h statistics, and the size is 82Mb (one file each day).
There is a section:

<statRecord type="interval" length="60" time="2019-07-16T08:23:59">
[download]

every 60secs.
My needed would be an output, more or less like this:

time|resourceGroup name|LCONNFAIL|LLOSTCONN|LIDLETIMEOUT|SIPADDR|SIPPO
+RT
2019-07-16T08:23:59|CSCS1SVGM1|0|0|0|amlif700txs001|28218
..and..so..on..until.the.on.file.

I've just tried XML::Twig, XML::LibXML and use Data::Dumper with XML::Simple(which is not so simply for me;-) ) with no success :(.
Thanks, again, to anyone who want to show me the right path/way to follow.
