Saleha,
Its showing absolutely correct error message. Did you notice that you are
suppose to pass an object as a parameter on this function? If you are doing so
$xml should be an object already and IFF it is, then why are you using $xml (as
an object) in the preg_replace function as 3rd parameter? According to
preg_replace function the 3rd parameter should be anything but array and object.
Thats why its failing. Example:

Syntax definition for preg_replace:
mixed preg_replace ( mixed $pattern , mixed $replacement , mixed $subject [, int
$limit = -1 [, int &$count ]] )

So, the 3rd parameter generally has to be a string. Also notice that you are
returning the value of that line 224 into $xml back again. This is
programmatically correct, but do you think you are running out of variable
names? Use some other variable name here.

To make your function working, I think you do not need object to be passed onto
this function, you need pure xml as a string into this.

Hope you will understand your problem now.

Thanks
Yamin
