DOM question - visiting a node's children?

[r_topor@yahoo.com]

As of PHP 5.1, why aren't there functions that return a node's
children, a node's first/last/nth child, a node's parent/previous
sibling/next sibling, etc., as in the DOM specification? How are you
currently meant to traverse a DOM tree without these functions? Or
perhaps they exist somewhere in the documentation, but not under the
list of DOM functions - if so, where are they?

Hi Rodney,

That is like asking: "Where are the rocket blueprints for the Saturn5 in
PHP?"

PHP is executed at the server, and returns a response, which can be HTML.
If you want to use DOM-specific functionality, this is executed by the
browser that receives the HTML produced by PHP.

PHP is completely out-of-touch with the HTML it delivered.

You need Javascript to access DOM in a browser.

Of course, this doesn't mean PHP cannot be used to deliver nice
Javascript/HTML/etc, but PHP is NOT in charge anymore once the HTML arrives
at some client (browser).

While I agree with the fact that the question was a bit odd, I think it
could actually mean another DOM tree, such as an XML DOM instead of HTML.
Perhaps the original poster is referring to some XML parser, who knows.
Point is that HTML isn't the only possibility here.

Yes, I'm talking about XML DOM. See Section VI-XXX. DOM Functions and
SectionVI-CLXVIII. XML Parser Functions, etc. As I understand it, all
these functions are used in PHP scripts on the server to process XML
documents as DOM trees in memory. (I'm not referring to HTML DOM which
is indeed used by JavaScript on the client.)

Hi Rodney

In the DOM functions childNodes,firs t/lastChild and parentNode are
properties of DomNodes

They are listed in the table just below the function list

http://www.php.net/manual/en/ref.dom.php#dom.class.domnode

You're not the only one who a problem finding them. I searched the
table of contents for ages wondering how I could use a dom without
childNodes...

Tim, Thank you! That answers my question. Glad to learn I am not
alone. Case closed!
