[xsl] Sum function

["Purnima Shankaran" <purnima@xxxxxxxxxxxxx>]

Hi,

I have  an xml like this

<storsys>
<storvol>
    <noofblocks>2</noofblocks>
    <blocksize>3</blocksize>
</storval>
<storvol>
    <noofblocks>4</noofblocks>
    <blocksize>5</blocksize>
</storval>
</storsys>

I want to display the total as sum of ( noofblocks * blocksize) for all
<storval> tags present.

Thanks for the help.
