[regexp] Get contents of div tags with overlapping tags

goa103

Hello,

I try to get the contents of div tags from the text below :

<div>Text 1</div>
<div><b>Text 2</b></div>

I would like to get an array like :
$div [0] = "Text 1";
$div [1] = "<b>Text 2</b>";

I use preg_match_all with the following regexp :
"/<div>[^{<]+<\/div>/i"}

The problem is that it stops when it finds a <, and I would like it to stops when it finds a "/div>".

I tried something like :
""/<div>[^{<\/div>]+<\/div>/i""}
But it doesn't work.

How can I specify it to stop when it finds a string and not just a character ? "</div>" instead of "<".

Thanks,
JM

$a="<div>Text 1</div>
<div><b>Text 1</b></div>";

preg_match_all("|<div>(.*)</div>|U", $a, $out);

var_export($out);

This should work.

he's using the | as an alternate delimeter to /. you can use almost anything, as long as you escape it in the body of the regexp. my personal favourite is #.
