如何在bbcode中包含文本？

Question

I need help with this preg_match script. I want to have a text that is inside a bbcode. So this would be the string: [caption id="attachment_123" align="alignleft" width="100" caption="This is the text that I want"]

How would you do this? The important thing is also, that the values like id and align wont be the same all the time. I tried something like preg_match('#\[caption(?:.*?)caption=\"(.*?)\"\]#s',$result,$array);

Thank you for your help! phpheini

My suggestion:

Replace [ and ] to < and > then convert that string to XML object using SimpleXML and access caption as a property of created object.

$input  = '[caption id="attachment_123" align="alignleft" width="100" caption="This is the text that I want"]';
$input  = str_replace(array('[', ']'), array('<', '>'), $input);

$object = new SimpleXML($input);

echo $object->caption;

Clean and easy. Regexp and HTML/BBCode is painful.
