Shame on me! It turns out the simplest Perlier version actually works!

It may not be official w3.org syntax, and doesn't work in XPather, but it does in HTML::TreeBuilder::XPath.

So in case other people search for this... to find attribute values macthing a regular expression using HTML::TreeBuilder::XPath :

  $tree->findnodes( '//element[ @attribute =~ /regex/ ]' );
