Calling Web Service Method from XSLT.

Hi,

I am displaying web page with XML and XSL, where some
part of the data I am getting from Web Service's
method ,current code is using VBScript function to
create XMLHTTPObject and sending request and getting
response back and that function is being called in
XSLT itself. But now I do not want to use VBScript
anymore, I would like to use XSLT itself to make a
call to Web Service
(http://localhost/abcservices/abc.asmx?GetHTML
and I don't know how to do it.

Question : How do i call WebService method which
returns just HTML in XSLT? 

It would be very helpful if anyone can guide me on the
same.
