can't answer 1 and 2 but 3)

use $node->tagname() instead of $node->name
use $node->content() instead of $node->content (works only with php from cvs or next release)

DOM XML is experimental extension. It has been changed a lot including API :)
Please read manual for more information. (I hope it's in manual)

Thanks for the responses, but they do not help:

(1)  chregu:  DomNode does not have a function content() in 4.1.1 - how do I get next release?  There is a function called node_value, but it does NOT work.  I looked at the source in 4.1 for node_value (4.1.1 "source" is a bunch of html files) and it looks OK, but requires object to have content property which does not appear to get set.

(2)  yohgaki:  Documentation at php.net does NOT agree with 4.1.1.

I realize that DOMXML is experimental:  May I suggest that the 4.06 experiment worked, but that the 4.1.1 experiment is having problems.

to get the latest version, download
http://snaps.php.net/php4-latest.tar.bz2 of domxml
and copy the ext/domxml directory to your php-4.1.1 source dir (or just compile the whole 4.2-dev version, if you are really adventureous...). afterwards (before ./configure) you have to do ./buildconf in the php source dir root.

node_value is only for DomText, DomCData, DomProcessingInstruction and DomComment Nodes. Not for DomElement nodes (and i think, that's what your looking for).

A solution for getting the content is at:
