Help! Expression problem!

[Anon]

Hi,

I'm really stuck with the following problem:

I have a variety of strings in a variety of formats typically similar to the following:

(LLLLNNNN AND LLLLNNNN) OR (LLLLNNNN NOT LLLLNNNN)

What I'd like to do is some substitution, so that before each combination there would be an "xxxxxxxx='" and then after each combination a "'".

So, in the example above I'd get:

(xxxxxxx='LLLLNNNN' AND xxxxxxx'LLLLNNNN') OR (xxxxxxx='LLLLNNNN' NOT xxxxxxx='LLLLNNNN')

I'm absolutely stuck on this and desperate for any help! Would really appreciate it if someone could help me out!

Thanks in advance

Paul

This should do...
<?
$myString = "(LLLLNNNN AND LLLLNNNN) OR (LLLLNNNN NOT LLLLNNNN)";
$myString = preg_replace("/([LN]{4,}[^{\s)]+)/","xxxxxxxx='\1'",$myString);}
echo $myString;
?>

OR actually, it looks like you wre needing something a bit more robust...

This would be a nice thing to put into a foreach loop to parse a large array of statement.

<?
$myString = "(AAAA9999 AND SAMBA1038) OR (LOSE0123 NOT MEET9898)";

//you can set this to whatever...
$varStr = "xxxxxxxx";

$myString = preg_replace("/([a-z0-9]{3,}[^{\s)]+)/i",$varStr."='\1'",$myString);}
echo $myString;
?>

Or even better...

<?
$myString = "(AAAA9999 AND SAMBA1038) OR (LOSE0123 NOT MEET9898)";

//you can set this to whatever...
$varStr = "xxxxxxxx";

$myString = preg_replace("/([a-z]{4}[0-9]{4}[^{\s)]+)/i",$varStr."='\1'",$myString);}
echo $myString;
?>

this one is more explicit, each value set MUST be exactly 4 letters followed by exactly 4 numbers
