not sure parseing html is going to help here.. it has to be preg_replace ... I need the pattern is the thing .. tk — Quantum, May 10 '11 at 11:59
I'm sure it *will* help :) and it's much more reliable than using Regex. — Gordon, May 10 '11 at 12:35
What do you want to replace? The complete row where "message" is found? — stema, May 10 '11 at 13:41
what the deal is that I am working in smarty so I need to match the value of the input who's name ends in "message" and use the callback to replace it all. the smarty is {$foo|regex_replace:'/patteren/':'replace ie: $1'} so at the end $foo is "The value specified for "Email" is already in use by another registered user" .. oh not stated below is that $foo is that whole html block above. — Quantum, May 11 '11 at 22:37

You're looking for .? (0 or 1 of any character except a new line). I think you should look for [^"]+ i.e.: /message" value="([^"]+)"/is and replace with $1 (not sure why the other brackets are there unless that's for something else).

nope that didn't work either.. the other groups where to match the outside so when I replace with the call back the whole mass is replaced.. of that is the intent :) – Quantum May 10 '11 at 12:07
Why do you want to replace? Can't you just put the match into a new string? – Lee Kowalkowski May 10 '11 at 12:31

Oooo! Smarty... and I've just noticed the single-line-mode modifier. – Lee Kowalkowski May 12 '11 at 07:21
So I see that this means you want to replace *everything* with the message. In which case the non-greedy `.*?` at the beginning and end will match nothing, because they don't have to. You can force them to by putting `^` at the start and `$` at the end, or by just using greedy expressions, e.g: `/.*(message" value="(.*?)").*/is` or `/^.*?(message" value="(.*?)").*?$/is`, or even `/^.*(message" value="(.*?)").*$/is` - That's the only problem I can see anyway. – Lee Kowalkowski May 12 '11 at 07:54
