Åbne en ASP fil

Jeg har lavet et konverterings værktøj i XSL/XML, som jeg får vist på en hjemmeside. Alt virker fint, men nu vil jeg gerne have at brugerne, skal kunne uploade deres egen XML fil. Jeg ved bare ikke hvordan jeg skal gøre det. Her er min kode, til det statiske:

<%
'Load XML
set xml = Server.CreateObject("Microsoft.XMLDOM")
xml.async = false
xml.load(Server.MapPath("test.xml"))

'Load XSL
set xsl = Server.CreateObject("Microsoft.XMLDOM")
xsl.async = false
xsl.load(Server.MapPath("test.xsl"))

'Transform file
Response.Write(xml.transformNode(xsl))
%>

Jeg vil gerne have ændret Load XML til at man kan bruge sin egen XML fil, og ikke en der ligger på serveren. Tak! :)

Der vil du nok blive nødt til at uploade filen til serveren først, er jeg bange for.

Kan man så vælge en form for "gennemse" / "upload" og så behandle filen automatisk?

Ikke uden først at kode selve upload-funktionaliteten, så vidt jeg ved.

Hvor kommer .NET ind i billedet ? (ovenstående ligner ASP)

Jeg har lavet upload funktionen... og den virker fint.... jeg ved bare ikke hvordan jeg skal kode de 2 sammen. :-(

Når den er uploadet indsætter du vel bare filstien/filnavnet i stedet for "test.xml".

Ja, det er så lige det jeg ikke kan finde ud af at gøre... :-)

Da filnavnet er noget brugeren bestemmer, så ved jeg ikke helt hvad jeg skal gøre...?

Men kan det ikke hentes ud fra din upload? Uden at kende uploaden, kan vi jo ikke hjælpe dig videre.
