What I
really want to get out of this regex is
1) image name
2) image alt text
3) image title text
, so only those three parentheses are of capturing
kind and the rest is marked as non-capturing...
I wonder will this work (if I change this part):
(?:
(?:title\s*=\s*(?:"|\')) # title
(?>\b\S*\b)
(?:"|\')*\s*
|
(?:alt\s*=\s*(?:"|\')) # alt
(?>\b\S*\b)
(?:"|\')*\s*
)
, notice the "or" character. I guess it should
match, as the order is not important now...
I love monster regexes ;8].
