[xsl] How to simplify the xslt expression for multiple conditions

["Yang" <sfyang@xxxxxxxxxxxxx>]

Hi,  Jeni,  I hope you can help me on this;

I am addressing a  problem as follows;

   **to  rank each salesperson of each store based on the sales amount on
each day for the given month **

and find out I have to repeatedly apply the following lengthy and tedious
expression for multiple filter conditions
to the xslt codes.

[not(string($month)) or substring(@SalesOrderNo,10, 2) = $month]
[not(string($dayID)) or substring(@SalesOrderNo,12, 2) = $dayID]
[not(string($timeID)) or substring(substring-after(@CreateDate,'T'),1,2) =
$timeID]
[not(string($salesID)) or normalize-space(@SalesCode)=$salesID]
[not(string($customerID)) or normalize-space(@CustomerCode)=$customerID]
[not(string($storeID)) or normalize-space(@StoreCode)=$storeID]
[not(string($salenoID)) or normalize-space(@SalesOrderNo)=$salenoID]

As this piece of filter expression has to be hard-wired with each key
function and sort function(it
will not function correctly if using variable) , it concerns
me the  maintenance problems whenever new conditions have to be added.

I would like to know is there a smart way  to show me how to keep this
coding update easily and cleanly.

Thanks any help in advance.

Sun-fu Yang,
