["NILESH PATEL" <jayganesh786 at hotmail dot com>]

Dear Friends,

I am trying to achoeve simple calcuateion from xsl. I do not know the way 
out of this. Please help. Here is the code.

XML:
======
<Shopping>
	<fruits>
		<apple quantity="10" unit_price="1"></apple>
		<orange quantity="20" unit_price="5"></orange>
		<banana quantity="30" unit_price="5"></banana>
		<grapes quantity="40" unit_price="5"></grapes>
	</fruits>
	<vegs>
		<onion quantity="10" unit_price="5"></onion>
		<carrot quantity="5" unit_price="10"></carrot>
		<chiili quantity="20" unit_price="5"></chilli>
		<tomato quantity="10" unit_price="5"></tomato>
		<potato quantity="20" unit_price="5"></potato>
	</vegs>
</shopping>

XSL:
======
//suggest xsl template here, because I tried using sum() and numbers and so 
on but could not work the way around it. I could do individual 
multiplication using <xsl:for-each select="//fruits/*">. but did not achieve 
results.SO I BEG TO THE COMMUNITY, PLEASE HELP ME NOW.


Required Result:
=================
FRUITS:  (10*1) + (20*5) + (30*5) + (40*5) = 460
VEGS  :  (10*5) + (5*10) + (20*5) + (10*5) + (20*5) = 350



Basically, I want to multiply "quantity" and "unit_price" first then add the 
multiplication-result.May be using javascript or xsl built in functions, 
please suggest.

Thanks very much in advance.
