I would definitely give XML::LibXML a try. It has a nice command line tool, xmllint, which can make wonders if used correctly. On the other hand, if you want Perl, you should experience with setting the recover flag of the XML::LibXML::Parser object to true. Although the manual states that it is for parsing HTML, it, as far as I can tell, serves for parsing ill-formatted XML just as well.

The quick and dirty hack below could repair your badly formatted XML snippet (after adding the missing namespace declarations): 

use XML::LibXML;
my $parser = XML::LibXML->new();
$parser->recover(1);
my $doc = $parser->parse_file($ARGV[0]);
print $doc->toString(1);

Note that, however, I am not entirely sure that it always gueesses right on adding the remaining closing tags back, so I would not rely on this feature...
