a)  '^' matches at the beginning of a line.  So if 'href=' is at the
beginning of the line...

b)  Regexes are hard enough to read as is.  (http|ftp|https) is more
readable than ((ht|f)tp(s?).

c)  If you're going to parse html/xml then bite the bullet and learn one
of the libraries specifically designed to parse html/xml.  Many other
regex gurus have learned this lesson.  Myself included.  =)
