RE: node-set() function in MSXML?
Thanks, Mike. I have one more question. If XSLT had originally had native support for accessing RTFs as node sets, would it have looked any different than what MSXML does (ie. just referring to the variable without a node-set() function)? Or is there a semantic difference between the two such that it would only make sense if you tacked on an additional function to indicate that the RTF is being accessed as a node-set? In other words, in future versions of XSLT, should this support then be added as a node-set() function (as you suggest on page 462)? And, if so, would that only be because that's the way it has been done in the past (Saxon, xt's node-set(), etc)? Or, if they were starting from scratch again, would it make sense to simply allow the RTF to be accessed as a node-set without any functions, as MSXML does? I'm trying to put my finger on why the spec allows only a subset of the operations permitted on a node-set. I can understand what they are, but not why. <excerpt> A result tree fragment is treated equivalently to a node-set that contains just a single root node. However, the operations permitted on a result tree fragment are a subset of those permitted on a node-set. An operation is permitted on a result tree fragment only if that operation would be permitted on a string (the operation on the string may involve first converting the string to a number or boolean). In particular, it is not permitted to use the /, //, and  operators on result tree fragments. When a permitted operation is performed on a result tree fragment, it is performed exactly as it would be on the equivalent node-set. </excerpt> Thanks, Evan Lenz elenz@xxxxxxxxxxx -----Original Message----- From: owner-xsl-list@xxxxxxxxxxxxxxxx [mailto:owner-xsl-list@xxxxxxxxxxxxxxxx]On Behalf Of Kay Michael Sent: Wednesday, August 02, 2000 10:56 AM To: 'xsl-list@xxxxxxxxxxxxxxxx' Subject: RE: node-set() function in MSXML? > I tried your stylesheet with Saxon and with MSXML3, and it > worked for both. > However, I still don't entirely trust it.

The stylesheet is portable among a finite set of known XSLT processors. Which is better than not being portable at all.
