[Javascript] Client-side Word document creation via XML/XSLT

[Dave Shaw]

This is going to be a bit long. Please bear with me.

I have a package called the Data Integration Toolkit (DIT) by CorasWorks
in one of my SharePoint environments. I can use this to fetch data in
XML format from nearly anywhere, including native SharePoint content,
then apply XSLT transforms against it for display on SharePoint web part
pages. I've gotten some very nice custom displays from this. I've
managed to also use the DIT to apply an XSLT template with WordML markup
to get SharePoint list content in a nicely-formatted Word document in
Word 2003 XML format.

I support another SharePoint environment that does not have the DIT
available. I'd like to accomplish some of these same things in that
environment. I figure I should be able to do all this client side. I've
managed to get the SharePoint list content in XML format (owssvr.dll is
your friend), and I've written a little Ajax code to fetch the data and
template, do the transform, and stuff the results into the innerHTML
property of a <div> for the onscreen displays. Works great; gives the
same results as my DIT tools.

As to creating a Word document... Using the same data and WordML
transform as I have on the DIT-enabled server, I've managed to do a
transform and I have what I believe to be the resulting XML/WordML in a
variable. It's about the right length, anyway (700K bytes). The problem
is that I can't for the life of me figure out how to get it from
Javascript into Word.

If I put this exact data in a file (document produced by doing the
transform offline) sitting on the server, and I open that in IE, IE
offers me an open-or-save dialog and I'm good; Word opens a
properly-formed and perfectly-formatted document. The URL is of the form
http://server.address/library/test.xml. Simple stuff.

Ideally, I'd like to simulate this on the client - provide appropriate
headers and the contents of the javascript variable to IE to open as if
it were streaming from a web server. I've tried playing with the window
object but I'm getting nowhere; IE just tries to write the output as raw
text to the browser window. Not useful. I've played with ActiveXObjects
but to no avail; I keep getting prompts to run the ActiveX control, and
then Word won't open. Even if it did, I find nothing in the Word object
model that leads me to believe that I can provide my Javascript/WordML
as if it were coming in through File->Open. Also, I'm not a fan of this
approach for portability reasons, but if I could make it work, I'd be a
good couple of steps ahead of where I am.

Google is leading me in circles. I keep finding the same
not-so-very-helpful web pages.

In a nutshell, I'd like to present HTTP headers and the transform
results (XML/WordML) created in the client browser to the same client
browser in such a way as it acts as though I'd opened it from a web
server.

Can anyone give me a nudge in a useful direction?

Thanks,

Dave Shaw
