Here are a few resources I found interesting/useful.  They
are totally DOM-centric ... although
the PHP DOM interface is highly non-standard.

http://www.php.net/manual/en/ref.domxml.php

The "user contributed notes" are the most useful part of the manual!

Here's a trivial php program that takes a POST of an HTML form
(the names of the fields are automatically represented as PHP
variables), opens an RSS-like file identified by the $file value,
and puts the form information in a new "item" element at the bottom
of the first "channel" element, then rewrites the file and echoes
its contents to the browser. 

<?php

  header ("content-type: text/xml");

    	$file = "http://localhost/log/"; . $arch . ".xml";
    	$doc = xmldocfile($file);

	$ctx=xpath_new_context($doc);
	$c=xpath_eval($ctx,"//channel");
      $r = $c->nodeset[0];
	$i = $r->new_child("item");
	$i->new_child("title", $head);
	$i->new_child("link", $link);
	$i->new_child("description", $comment);

    	$out = domxml_dumpmem($doc);
    	$file = $arch . ".xml";
    	$f = fopen($file, 'w');
    	fputs($f, $out);
    	fclose($f);

	echo $out;
?>


I am a complete PHP novice, so any
suggestions to do things in a more sensible way would be appreciated.
