dom abstraction package

Greetings from userland,

[Tried posting this through the newsgroup interface, but it doesn't seem
to have made it.]

I've just posted a package proposal to pear-dev for a dom abstraction
package:
http://news.php.net/article.php?group=php.pear.dev&article=18170
I thought I'd mention it here for a couple of reasons.

First, there was some discussion on this list about it months back, and
that's what prompted me to eventually sit down and do it.

Second, it includes a test suite which checks the packages for
DOM-compliance (1, 2 or 3). This has a 'raw php5 mode' which runs the
same tests (approx 200 and counting) over PHP5's dom extension. I
initially did this to help me write the abstraction classes for this,
but now it's (sort of) working, I thought it might be of some use to
you.

Last, I've got some questions that came up making the test suite. Not
sure all are actual bugs - if they are let me know and I'll enter them.

1. There's no NodeList or NamedNodeMap objects - getElementsByTagName et
al just return arrays. Is it likely to stay like this?
2. I've seen some weird things happening accessing class properties, and
am wondering if it's a bug.
    if ($node) {...}    // never true, even when $node
                  	// is a real dom object

    return $doc->documentElement;    // returns null, but...

    $el = $doc->documentElement;
    return $el;            // returns element as expected!

3. the data attribute of domCharacterData descendents (Comment et al)
returns domtext instead of a string. (My tests mess this one up too -
will fix).
4. 	$doc->implementation	// segfaults
5. Many more... will post once I've got my head round them. 

Environment: php-5.0.0b1 (command line), libxml 2.5.8, kernel 2.4.18 

Have a  good weekend,

Matt
