Re: Compiled XSLT stylesheets

There is "compile" and compile ;)

Saxon always "compiles" a stylesheet in the sense that it goes through a processing phase where the stylesheet is analyzed. In Orbeon Forms, usually such "compiled" stylesheet are cached when possible (most of the time).

Now there is more to it if you check the Saxon product matrix:

http://saxonica.com/feature-matrix.html

If I understand well, Saxon can compile XQuery to native Java code, which "typically gives a 25% performance boost", but not XSLT yet. Also, Saxon can serialize "compiled" XSLT to disk, but "this feature does not normally deliver performance benefits".

At any rate, these are available in the commercial versions of Saxon only.

I suggest you ask on the Saxon mailing-list, or directly Saxonica / Mike Kay about which specific compilation feature could actually deliver increased performance to your stylesheets. And please report back here :)

Hi,

I understand it is possible to 'compile' XSLT stylesheets using a saxon
extension. Does anyone know if the Orbeon standard XSLT processor, oxf:xslt,
uses this feature? If not, is this a straightforward extension, or would
require a new custom processor?

Regards,
Neil
