I don't suppose any BCFers know their way around regular expressions do they? Confused

Atm I'm having an absolute nightmare trying to make one which will find the following code inside some HTML:

Code:

[div class="mosimage_caption" style="width: ; text-align: center;" align="center"]Tamada on the RC211V[/div]


The problem is, the caption (text in between the divs) and the div parameters will vary (with the exception of "<div class="mosimage_caption"") so it's tricky as hell to get to work.

My best attempt so far is:

Code:
(\[div class="mosimage_caption").*(\[/div\])


But that always matches everything right up to the last instance of [/div] because of the .* code which is matching everything and then backtracking... I need it to match just up to the first instance of [/div].

Fecking hate these things. Evil or Very Mad If anyone can help I will owe them big time... I've wasted so long on this it's crazy.

You should look into 'non greedy' matching, for the regex engine you are using.

Not a lot of help, but hopfully a pointer in the right direction...

I'd looked into that a bit but not had a clue what to do. Bit of investigating into PHP and it seems all I needed was an extra question mark. Very Happy Cheers dude, that was the push in the right direction that I needed. Thumbs Up

Code:
(\[div class="mosimage_caption").*?(\[/div\])

Easy. In your .* for matching the bit inbetween the divs, rather than saying "anything" you need to say "anything except a /div tag".

So, replace the .* with something like [^\[\/div\]]*

Very Happy

EDIT/ your way is neater. Thumbs Up
