How can I pass a querystring to an XML SYSTEM uri?

[Parsifal1970]

I'm using an xsl stylesheet to transform an xml source from a remote URL. I'm using the xslt.pl processor available from "

http://www.dopscripts.com/doc/description.html".

The remote URL is placed at the beginning of my stylesheet as a SYSTEM uri as follows

<?xml version="1.0"?>
<!DOCTYPE my-news [<!ENTITY news SYSTEM "

http://path.to/xmlfile.xml">

]>
<xsl:stylesheet version="1.0">
<xsl:variable name="news">&news;</xsl:variable>
<xsl:template match="/">
<xsl:for-each select="$news">

...

</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

Now say the url of the XML source is "

http://path.to/xmlfile.xml?id=*id*"

where *id* is a querystring parameter, is there any way of passing this value to the SYSTEM uri?
