Overly idiomatic but this was for fun, not production :P–

use XML::LibXML;

my $doc = XML::LibXML->load_html( location => "example.html",
                                  { recover => 1 } );
my @ids2text = map { [ $_->value, $_->getOwnerElement->textContent ] }
    $doc->findnodes('//@id');

$_->[1] =~ s/\W+//g for @ids2text;

print join ", ", map sprintf("%s=%s", @$_), @ids2text;

While this happens to be XHTML

Sidenote on that. I am sure you know the sample is not XHTML but I thought I'd call it out for the sake of readers.

Update: I missed the "transitional" part of the XHTML declaration. It is indeed, shockingly, valid transitional XHTML. Goes to show how on point haukex is on this matter.

Update 2: updated node title per LanX. Pulled strict/warnings to shorten post. Plus link to module: XML::LibXML
