[Tclxml-devel] TclDOM Checkin

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

Just checked-in my changes to the TclDOM v2.0 package.

One minor bug fix (for creating doc type declaration).

Major changes are to the XPath support.  Introduced selectNode
method to the DOMImplementation and node commands.
While there is still a long way to go towards full XPath support,
this code lays the groundwork for the architecture.

At this point, the child, descendant, descendant-of-self and
attribute axes are supported.  All node tests, including type
tests, are supported.  Only simple predicates are
supported - no functions.  My main aim was to be able to
handle constructs such as //*[@id='foo'] (find all elements in the
document with an attribute named 'id' with the value 'foo'.
The id function is of no use because the parser is non-validating).

Similar constructs will also work, such as //sample/example[@bar='foo'].
Relative location paths are OK too.  Other expressions, 
such as example[@foo] or foobar[shazbat] may work, but I haven't
tested them yet.

I've also caved-in and started supporting Attr nodes, since these are
needed for XPath.

Enjoy,
Steve Ball
