Help me rewrite this regex to not match tags with attributes?

Question

=========================================================================

EDIT: I'm using node.js, so I don't have access to the DOM, and parsing with an HTML parser is not an option (it's not efficient enough to justify parsing through such a small amount of text)

=========================================================================

First off, I know. HTML + Regex = fail. However, I just need it to remove all tags with attributes.

Here's what I have so far:

    exports.strip_tags = function(input, allowed) {
      // Strips HTML and PHP tags from a string
   allowed = (((allowed || "") + "")
     .toLowerCase()
     .match(/<[a-z][a-z0-9]*>/g) || [])
     .join('');
      var tags = /<\/?([a-z][a-z0-9]*)\b[^>]>/gi,
      commentsAndPhpTags = /<!--[\s\S]*?-->|<\?(?:php)?[\s\S]*?\?>/gi;
      return input.replace(commentsAndPhpTags, '').replace(tags, function($0, $1){
        return allowed.indexOf('<' + $1.toLowerCase() + '>') > -1 ? $0 : '';
      });
    }

Any chance someone know's how to change up one of these regex's to make this remove what I need it to?

To clarify: This function should remove all tags with attributes, keep only the tags that are allowed (without attributes), and output the result.

Convert it to XHTML and then use xpath.

As you said.... HTML + Regex = fail
