I can see that xupdate can be a replacement for xsl: Start with an empty document, then update it into shape, instead of creating it with xsl.
Or one could use xsl instead of xupdate, creating the whole document again using both the original and the updates as sources. However, from an efficiency point of view there will be cases where one is more suited than the other. As for combining the two, perhaps we should take a lesson from Unix and keep each thing as simple as possible and instead make a pipeline of many simple xslt:s and xupdates when we have a complex problem to solve. Xalan supports pipes of xslt filters, just combine a series of SAX-sources and SAX-inputs. /tobe > -----Ursprungligt meddelande----- > Från: Lars Martin [mailto:[EMAIL PROTECTED] > Skickat: den 11 januari 2002 09:58 > Till: [EMAIL PROTECTED] > Kopia: [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED] > Ämne: Re: Is there xml-diff which produces output in xupdate? > How can I > mix xupdate and xsl? > > > On Fri, 11 Jan 2002 04:30:20 +0100 (CET) you wrote: > > > From [EMAIL PROTECTED] Fri Jan 11 04:30:20 2002 > > Return-Path: <[EMAIL PROTECTED]> > > From: "Mikhail Grushinskiy" <[EMAIL PROTECTED]> > > To: <[EMAIL PROTECTED]> > > Cc: "Grushinskiy, Mikhail, ALVAP" <[EMAIL PROTECTED]> > > Subject: Is there xml-diff which produces output in > xupdate?
