RegEx Expression Trouble

HowdA All,

I am hoping one of your gurus can help we out with a small regex problem.

What I want to do is find all occurrences of "my test" in the following string:

PHP Code:


		
			
$text = "my test<ul><li>my test</li></ul> <b>my test</b> my test <i>my test</i> <!--nope--> my test";

Easy huh? However the real catch is that I want to find ALL of them EXCEPT  my test

So this is what im doing now:

PHP Code:


		
			
#(\b((\s|<li>|<strong>|<b>|<i>)my test)s?\b)#im

Which catches all of them. How can I do it so it explicity DOESNT catch the last one?

Thanks all!

Sorry eyes are already giving me a hard time in keeping them open. If you would have posted this in the morning i would have given it a go.

Might want to wait for Dean to reply.

Mrs Geek is too busy trying to find Regex for her new 'Get Geek to Wash Car Module 1.05'

Happily I have stuck it in a really good place where she should never find it :)

Any help when you can is appreciated

AAAAAAAAAAAAAARGGGGGGGGGGGGGGGGGGGGGG I FREAKING HATE AUTOMERGE.

How the hell are you supposed to bump something with auto merge?

I need to find a way to get around this.

Does the <!-- nope> also have a closing tag, or is everything after that ignored?

Hey Marco,

The tag was , however I THINK I have found the solution like this:

PHP Code:


		
			
#(\b((?<=\s|<li>|<strong>|<b>|<i>)(?<!nope--> )my test)s?\b)#im

Basically, I wasnt properly doing a look ahead assertion.

Thanks for your help.

Yep, look ahead is the way to go.
