Let's break this down and see if you can't find the problem:

/(<p> )    # #1
(.+(?!<p>)) # #2
(features\: <ul>)/ix) # #3
[download]

1. the pattern must start with <p> followed by a space
2. afterwhich the pattern must grab as much as it can provided that #3 is statisfied and that whatever .+ matches cannot be followed by <p>.
3. the pattern has to end with features: <ul>
all this is case insensitive.

so if you look at it once more you realize that nowhere is rule #2 broken as it is not followed by a <p> what you are looking for is more along these lines:my ($first, $second, $third) = ($test =~ /(<p> ).+?<p>(.+)(features: <ul>)/i);

update:being human, I assosciate significance to big round numbers in a, more often times than not, strange superstitious manner. and thus i mark post 100
