Just when one thinks one has become a “Regex Master”, how soon we are humbled to learn new tricks that define a previously hidden new higher level. After taking the time to absorb the subtleties embedded in this post, I come away richer.

I learned 2 new tricks:
1.) How to capture randomly ordered items in a known order.
2.) How to simulate atomic grouping by combining lookahead with a sacrificial capture group.

Both are gems. Thank you!

How would one make sure at least n attributes are matched? I have the following: (?:]*)"?|class="?dataElement"?|id="?([^"|\s|>]*)"?)|[^\s>]+|\s+))\1)*>(.*?)(?:|) And I would ideally like to match span's that have datafield, dataelement and id (in any order). I've tried using {3,} but I don't think it was a applied as assumed due to the last sequence in the optional capturing group that says all but " \s or >. Your help would be greatly appreciated.

@Philip, I'm not sure I understand what you're trying to do, since bold, italic, and underline are merely values for their related CSS properties. If you're just checking for the existence of certain words within your style attribute, that's unrelated to this post. Also, you haven't mentioned which regex flavor you're using. In any case, if you need one-on-one regex advice I'd recommend regexadvice.com or the RegexBuddy forums.
