Re: [xml] namespace-alias result-prefix

[cazic gmx net]

Hi,

This issue is related to
http://bugzilla.gnome.org/show_bug.cgi?id=341325
and a bit of
http://bugzilla.gnome.org/show_bug.cgi?id=313711

I changed the processor to generate the "result-prefix" prefix
in the refactored code paths (define XSLT_REFACTORED); but since
I cannot foresee when we'll be able to enable this code,
a patch for the current behaviour would be good, I think.
The current code performs aliasing during transformation, every
time it hits a literal result element; the refactored code
computes the result prefix/namespace at compilation time.

Note that Xalan and the old Saxon behaves the same way
as Libxml2 currently does for XSLT 1.0. Only in the XSLT 2.0
spec, the resulting prefix needs to be the "result-prefix";
but the prefix still might be changed if there's a namespace
clash (a rather unlikely scenario).

(by the way: direct Libxslt related issues to xslt gnome org)

Greetings from the unemployed front ;-)
