This seems to work for me. You mentioned wrapping a root element around it, but did you include the <?xml ...?> bit? Even when I remove that, though, it still works. Does it fail with your sample file?
#!/usr/bin/perl
use XML::Simple;
my $xml = do { local $/; <DATA> };
my $hash = XMLin( $xml );
use Data::Dumper; print Dumper( $hash );
__END__
<?xml version="1.0"?>
<root>
<CVS>
$Id: File_Find.pl,v 1.1 2006-12-17 19:25:03 eric Exp $
</CVS>
<DATE>2006-12-10</DATE>
<INTRODUCTION>Blah</INTRODUCTION>
<TITLE>Foo</TITLE>
<AUTHOR>Bar</AUTHOR>
<ARTICLE>
foo bar baz
</ARTICLE>
</root>
It looks like the hash does what it should:
]$ perl test
$VAR1 = {
'INTRODUCTION' => 'Blah',
'CVS' => '
$Id: File_Find.pl,v 1.1 2006-12-17 19:25:03 eric Exp $
',
'ARTICLE' => '
foo bar baz
',
'TITLE' => 'Foo',
'AUTHOR' => 'Bar',
'DATE' => '2006-12-10'
};
Update: If I move the data out to a file and use XMLin( $ARGV[0], NoAttr => 1 ) it still works.
