Euhm, nope. you start on an undefined tag (lose the blockquotes around =
'[html]'), and you;re matching the html tag, not the head tag.

Could be done by setting a greedy match starting on a quote untill the =
endquote. Then again, if you're concerned with invalid attributes, you'd=

have to allow for the possibility the quotes are erronous too, i.e. =
someone forgot to open or close them.
I've taken a stab at it with regexes in the past, which works quite well=

as long as you can be sure it's stricly valid HTML. If it isn't, or you'=
re =
using outside sources where this isn't known, don't use regular =
expressions for something a parser ought to be doing.
