[xsl] [ANN] Saxon-CE 1.0 (XSLT 2.0 on the browser)

2012-06-15 16:26:46
Hi Michael

Just read this about Saxon-CE " the ability to launch Saxon from the 
xml-stylesheet processing instruction via an XSLT 1.0 bootstrap stylesheet came 
from a chance remark during the XML Prague conference, but it will make a big 
difference to anyone trying to migrate an existing XSLT 1.0 application." Does 
this mean any app that uses XSLT1.0 (i.e. non browser) could use it?

Regards

Mark

After a long gestation period, we are pleased to announce that Saxon Client 
Edition is now a product.

This means that finally, XSLT 2.0 is available on the browser. For practical 
purposes, that means every browser.

I feel this is a pretty significant event; it's doing what XSLT was intended to 
do all those years ago, of serving XML content and leaving all the presentation 
and interaction logic to happen client side. In fact it goes a lot further than 
the original concept, because it allows XSLT to be used not only for generation 
of (HTML + Javascript), but it also cuts out the need to write Javascript since 
all the user interaction can now be handled in XSLT as well.

It's not open source, but there's a free license for small organizations, and 
it's our hope that the pricing is sufficiently attractive to give good value to 
everyone. Licensing is on a per-web-domain basis.

If you've been following progress through the alpha and beta releases, the 
changes in the final product are mainly about creating interfaces to allow much 
closer integration with the browser environment (via Javascript APIs), as well 
as a lot of detailed engineering work on logging, diagnostics, debugging 
features and the like, and of course performance. We've had excellent feedback 
during the beta release and most of the suggestions that came back from users 
have been incorporated. As well as the demos we have created ourselves, the web 
site links to some fascinating applications built by users.

Special congratulations to Phil Fearon who joined Saxonica with the task of 
turning Saxon-CE from a prototype to a product and has completed that task 
admirably.

Congratulations!

I really hope this will be a game changer.

I am interested to tweak the XPath Visualizer for XPath 2.0 (which is now a 
.NET WinForms application) into one that uses Saxon CE and can be run in any of 
today's major five browsers.

Is there an option to package Saxon CE (local machine) only with a particular 
app, so that the app users will not be required to obtain and re-register a 
license? There may be a class of users that aren't XSLT developers but need to 
learn XPath 2.0 using an in-browser tool.
Such people are better spared the need to obtain a license that they aren't 
going to use but inside the App.

Needless to say, the App + SaxonCE integration should not allow use of SaxonCE 
separately from the App (something that I believe is the case of how oXygen and 
Saxon are bundled together at present).

Cheers,
Dimitre.

Not at the moment. We've always known such requirements would come up, but we 
put them to one side to worry about once we had the basic end-user product out. 
There's a whole load of ways people are going to want to configure this 
technology - Phil has been looking at the way Windows 8 uses HTML5 and 
Javascript for non-web applications, for example - and it will take us time to 
work out what hooks and interfaces we need to exploit all the opportunities, as 
well as the commercial offerings we need to put in place.

Just to expand on Michael's comment on hooks and interfaces: Saxon-CE currently 
has a capability to make function calls to an app hosting a web browser via the 
window.external object. There's just one function supported, saxonErrorHandler 
- for sending error and diagnostics messages (like xsl:message or fn:trace() 
output) to the host
applciation[1]:

To initiate the 'bridge' connection (to check the function exists within the 
external object), Saxon-CE's first call uses a special INIT logLevel - so one 
simple solution would be for the host app to send a license key in response to 
this first call. I'm getting into solution space too early here, but the main 
thing is that this is certainly feasible from a technical standpoint.
