Interesting. ZPT's implementation doesn't have any way of supporting
this, although one or more of the alternate TAL implementations may be
more easily extensible.
You're essentially trying to make your own mini-language here, and while
I won't dispute that this would be useful for you, a generalized version
of this capability would take a lot of thought. Your best bet may well
be a quick&dirty hack along the lines of inserting regex-based search
and replace on your templates before they're compiled. Something along
the lines of (WARNING: UNTESTED!):
txt = re.sub(r'<my-ns:([A-Za-z]+) ([^>]*)>',
r'<tal:my-ns replace="python:ms-ns.\1(\2)" />',
txt = re.sub(r'&my-([A-Za-z]]+);',
r'<tal:my-ent replace="\1" />',
You could patch or monkey-patch a call to your transformation into
PageTemplate.py's _cook() method.
