[xsl] javascript result in xsl variable

[Vaduvoiu Tiberiu <vaduvoiutibi@xxxxxxxxx>]

long story short. I need a variable that has the value of the url, I need to
have a variable with the value of the url so I know where the user is...which
in javascipt would be equal to document.location.href.

I tried using somehing
like
<xsl:variable name="url">
<script>
document.write(document.location.href);
</script>
</xsl:variable>

but it
doesn't work. at this point I don't know if what i'm trying is possible but
i'm hoping it can be done. 
10x in advance
