RE: [xsl] XSLT in MSXML - removeParameter?

Martin,

Thank you so much! I think the ActiveXObject-chooser in my code defaults to the 
3.0 objects, so I'll add in some logic that'll make it try to retrieve the 6.0 
and then the 4.0 objects. I got it working by overwriting proc = 
proc.ownerTemplate.createProcessor() each time, but like I said, that seems 
really wasteful. I think I'll keep that logic around for the 3.0 objects, 
though. Aside from the changed security restrictions in the 6.0 objects 
(AllowDocumentFunction, ResolveExternals, etc.) that I already know to change, 
do you know of any other possible real differences in the processing between 
the 3.0, 4.0, and 6.0 objects? That is, if I switched from 3.0 to 4.0 or 6.0, 
would there be any real reason that my current transformations would stop 
working correctly?

Thanks again! I really appreciate it!

~ Scott

Now, this looked promising, until I tried it: myProc.addParameter("myParam", 
null);
This threw a "Type mismatch" error in IE. The same happened when I tried 
myProc.addParameter("myParam"), myProc.addParameter("myParam", undefined) and 
myProc.addParameter("myParam", null, ""). I tried 
myProc.addParameter("myParam"), but it threw a "Wrong number of arguments or 
invalid property assignment" error instead. If I try to remove the parameter 
with myProc.addParameter("myParam", ""), then it overwrites the default value 
in my stylesheet, like <xsl:param name="myParam" select="'defaultVal'" />.

Has anyone come across this issue before, and how did you deal with it? Is 
there really a good, supported, CORRECT way to do this within IXSLProcessor?

I have run some tests here, with JScript and MSXML 4 and MSXML 6 the 
addParameter("myParam", null) works flawlessly, it is only MSXML 3 that 
gives the type mismatch.
I realize that does not solve the issue as IE 6 and later come with 
MSXML 3 and not MSXML 6. On the other hand MSXML 6 is by now part of the 
platform on Windows XP SP 3 and all Vista versions so a library might 
want to use it instead of MSXML 3 if it is available.

Currently the best way to get public information from Microsoft on MSXML 
is to post in the MSXML forum on MSDN. I have done that here:
http://social.msdn.microsoft.com/Forums/en-US/msxml/thread/58ee0753-7014-48c9-b78f-a065dbbf1433
so you might want to check during the next days there if someone from MS 
posts about a workaround for MSXML 3.
