regexp help please!

OK.

Here's my pattern so far:

$pattern = '/ \<  ([[:alnum:]]+)  \> ( (?>[^<>]+) | (?R) )*   \< \/ \1 \> /Xx';

What I want to match is all the text between an opening and closing HTML-like tag. I want to allow for nested tags, so the regexp should match up until where the opening tag is properly closed.

Here is a test string:

$string = 'text <replace>comment1<fish>comm<replace>noddy asd</replace>ent2</fish>sdsdsds</replace>text2<gordon>doodle<food>asd</food>qw qwqw</gordon>  garn';

I am using the following call:

$chunks = preg_split($pattern, $string, -1, PREG_SPLIT_DELIM_CAPTURE);

What i need is a regexp which sets $chunks like this:

Array
(
    [0] => text 
    [1] => replace
    [2] => comment1<fish>comm<replace>noddy asd</replace>ent2</fish>sdsdsds
    [3] => text2
    [4] => gordon
    [5] => doodle<food>asd</food>qw qwqw
    [6] =>   garn
)

I am going nuts here. Please could someone put me on the right lines!

This seems to do what I want:

$pattern = '/ \< ([[:alnum:]]+) \> ( (?>[^<>]+) | (?R) )* \< \/ \1 \>  /Xx';

while(preg_match($pattern, $string, $captured))
{
   $string = preg_replace('/'.addcslashes($captured[0], '/').'/', '', $string, 1);
   $results[][$captured[1]] = preg_replace(array("/ ^\<$captured[1]\> /Xx", "/ \<\/$captured[1]\>$ /Xx"), array(), $captured[0], 1);
}

Are there any suggestions for improvement?
