Jochen,
The reason why your regex did not match was because between the
(<div
> style="float:left;">.*<div[^>]+class="icon">.*?</div>.*?</div>)+
blocks there is some space, so that's why only the first block would match,
and the rest of the HTML goes to the next pattern. By making the quantifier
ungreedy, you match all the blocks within the same pattern, so you could
even remove the + sign after the closing bracket as it is not needed.
If you wanted to really be able to match this block by matching multiple
repeating blocks, you would have to use a regex like this:
$regex = '#(<div[^>]+id="cpanel">.*?)'.
'((?:<div
style="float:left;">.*?<div[^>]+class="icon">.*?</div>.*?</div>\s+)+)'. //
note you need to account for the spaces and newlines (that's why \s+), plus
all the repetitions must be within the pattern itself
'(.*?</div>.*?</td>)#ism'; //
which produces the same result :)

Yes it does, thanks Ken!
so the trick is to find which part has become greedy inside?
