Regular expression, help.

[leonardo.calado@gmail.com]

Hi, I have the following text from database:

{geo:countries: fr|br|us|es}
Vivamus orci. Nunc eget risus adipiscing urna interdum tincidunt.
Aenean nec felis condimentum nisi rhoncus tristique. Cras fringilla
posuere nulla. Fusce eu justo.
{/geo}

{geo:countries: all}
Proin ac sem. Praesent faucibus libero nec quam. Cras id neque. Mauris
euismod eleifend elit. Mauris id sem. Donec odio.
{/geo}

{geo:countries: uk|jp|ch}
Vestibulum viverra metus vel diam. Maecenas eu purus. Etiam fringilla
eleifend libero.
{/geo}

I need split this information in array and show only content from
listed country or all countries.

I'm try using split()"http://www.php.net/split" function with regex,
but I'm not success, I try, try and try... and nothing, I try using a
pattern from regex.

Anybody help me?

Thanks for all.
