I read it in its entirety in 1999. (first edition)

I think it is a excellent book. However, i don't think it as a
practical, necessary, book, for average professional programers who
works with text a lot (such as web app developers and sys admins).
Because:

* in my extensive use of regexes, daily, since about 1998 working in
the web application industry and sys admin, i only need to use
advanced regex maybe once or twice a year.

* most complex regexes needs, are more practical to be implemented by
breaking down into 2 patterns to test on (as opposed to a single
complex regex).

* when you need advanced regexes, the regex very quickly cannot handle
the job. You need either to break it into several regexes with nested
if statements, or you need a parser.

in the above, by "advanced regexes" i mean non-grouping constructs of
the form (?...), boundary anchors, nested patterns... etc.
