[Tclxml-devel] CVS Checkin

[Steve B. <Ste...@zv...>]

Hi All,

Back from the Tcl Conference now... those trans-Pacific flights
are such a joy because they give you a loooong time to hack code!
Well, at least until the TiBook's battery runs out ;-)

I have checked in my changes to the TclXML, TclDOM and TclXSLT
packages.  The main additions are to TclXSLT; extension
elements have been implemented as well as preservation of
XPath object data types.

Implementing extension elements has opened a can of worms :-(
I'd stear clear of them until I've sorted out the implications.
Specifically, making nodes in the stylesheet available to the
application conflicts with TclDOM, since both TclDOM and libxslt
use the _private hook in the xmlNode structure.

Preserving XPath object data types is a happier story.
XPath objects have four types: nodeset, boolean, number and
string.  These are mapped to a Tcl list of TclDOM nodes,
boolean, double and (surprise) string objects.  The return result
Tcl_Obj is mapped back to one of the XPath data types.
No more pesky parsing of string values!

Enjoy,
Steve Ball
