Guru, that you can be a Guru if you create a code conversion like "VB" to "Javascript" only using recursive regexp. ;) I just finished my own code conversion. Sorry my poor english, i'm brazilian!

After reading it, it made me more determined to work it out for myself, and I just did :) \w+\s*=\s*(["'\w])(?:(?:.*?\1)|[^\s|>]*) There may be an easier way but I've tested this and it works fine with attributes written like attr="val", attr='val', attr='hello "value"' and attr=val. I'm using it in a function that removes non-white-listed attributes (mostly to catch onmouseover, onfocus, etc). I probably wouldn't have been as determined if I hadn't read this post. I felt compelled to try and fit into a higher level, I'm probably a User with a few points in haxz0r. Go me!

There may be an easier way but I’ve tested this and it works fine with attributes written like attr=”val”, attr=’val’, attr=’hello “value”‘ and attr=val.

A guru should have learned that lesson long ago, and I don't think that how comfortable you are with "more advanced" parsing languages/tools/models is directly related to your level of regex mastery. Naturally, anything outside of my domain knowledge is going to be underrepresented. That’s already partially represented at the User level (“Knows when to use regexes…”).
