xsl and javascript

What I want to do, is when the xsl opens, use <xsl:variable> to get the data
i need in some variable x and then call a javascript function to open a new
window with that data and at the same time close the current window.

i got the part for the variable. but i cannot call a javascript function
within the body of the xsl file.

please advise.

Thanks,

TP.
