Execute asp page during transformation

During the transformation of an xsl 1.0 I need to execute a query placed in
a asp page.

I found in the forum if exist a call instance able to send a parameter by
querystring , but with no results.

I prefer no use the msxml embedded VBscript inside xsl, becouse it need the
database connection and it could be visible.

So the perfect one should be a call instance for e.g. 
<xsl:eval>http://mypage.asp?id=myparameter</xsl:eval>

But eval is not good to do this.

I hope some advice...
Thanks a lot.
