Re: [PHP] regular expression for (NOT 'word')
Try this... it should only print out "Some webpage data"
$text = "
script data.
Some webpage data
another script data
";
print preg_replace('/(.*?)<\/script>/',
'', $text);

I suspect that POSIX extended regular expression functions will not be
sufficient to do what you want. Most likely you will need to use the PRCE
functions (preg_replace, etc.) I tried to come up with a regex to do what
you are looking for but it's beyond me. I think it may have something to
do with what is called a "negative look ahead assertion", although I
couldn't personally get it to work. You can read about negative look ahead
assertions here:
http://www.perldoc.com/perl5.6.1/pod/perlre.html
You may be better off asking this question on a Perl newsgroup or mailing
list...

Re: [PHP] regular expression for (NOT 'word')
Ok let me explain my problem further some. I need the regular expression to
purify the html page from script tags:
I used: $file = eregi_replace("(.*)", " ", $file);
Now this works fine, until theres a webpage like:
script data.
Some webpage data
another script data
so the regexp above replaces everything between first and last
ie the webpage data also.
So i thought to change the regexp to something like this: $file =
eregi_replace("(NOT(script))", " ", $file);
where NOT(script) would match everything that contains word script
