$s = {dede:field name='keywords'}{/dede:field} 
{dede:field name='description'}{/dede:field} 
{dede:field name='title'}http://down.sucai.com/fonts/soft/071130/1_071204075903.rar{/dede:field} 
{dede:field name='writer'}{/dede:field} 
{dede:field name='source'}{/dede:field} 
{dede:field name='body'}{/dede:field} 
{dede:field name='pubdate'}{/dede:field} 
{dede:field name='litpic'}/uploads/allimg/c100112/12632b9420Z-412413.jpg{/dede:field} 
HTML;

$p = '#}(.+){#';

preg_match_all($p, $s, $r);
print_r($r[1]);
