Is really no one interested?

Who says that I have a well-formed DTD? DTD is not necessary in many
cases. I will illustrate with example why DOM is too "complex" ...
compared to SimpleXML.

<?php
//These are my 2 XML documents. No DTD - just a simple xml structure.
$xml1 = '<root1><q/><a><b><c><d>hi1</d></c></b></a><q/></root1>';
$xml2 = '<root2><q/><a><b><c><d>hi2</d></c></b></a><q/></root2>';

$sxe1 = new SimpleXMLElement ($xml1);
$sxe2 = new SimpleXMLElement ($xml2);

//Easy access to a node. It's great!
echo $sxe1->a->b->c->d;
echo $sxe2->a->b->c->d;

//But how can I understand what is the name of the root node?
$dom_sxe = dom_import_simplexml($sxe1);

//Hooray, we've got node name
echo $dom_sxe->nodeName;

//And what happens if element sequence changes? .
echo $dom_sxe->childNodes->item(1)->firstChild->firstChild->firstChild->nodeValue;
//... hm... I prefer SimpleXML.

use xpath :) as easy as simplexml and much more powerfull, IMHO

and noone said you should use exclusively dom.

Well, If you are free to change the XML structure at any time - where's the
point in wondering if an element is a parameter, a CDATA or an element? You
can change everything to element and CDATA and that's all. If you have a
fixed XML structure, that's not supposed to change, having a DTD is
obligatory in orther to maintain consistency of the format.
So, you can either work without using getType (since you define the XML
structure yourself), or use a more complex API that will serve you well.

<?php
//These are my 2 XML documents. No DTD - just a simple xml structure.
$xml1 = '<root1><q/><a><b><c><d>hi1</d></c></b></a><q/></root1>';
$xml2 = '<root2><q/><a><b><c><d>hi2</d></c></b></a><q/></root2>';

$sxe1 = new SimpleXMLElement ($xml1);
$sxe2 = new SimpleXMLElement ($xml2);

//Easy access to a node. It's great!
echo $sxe1->a->b->c->d;
echo $sxe2->a->b->c->d;

//But how can I understand what is the name of the root node?
$dom_sxe = dom_import_simplexml($sxe1);

//Hooray, we've got node name
echo $dom_sxe->nodeName;

//And what happens if element sequence changes? .
echo
$dom_sxe->childNodes->item(1)->firstChild->firstChild->firstChild->nodeValu
e; //... hm... I prefer SimpleXML.

The API is to be kept simple and what you are asking for can be done
extending the SimpleXMLElement and the functions are a whole 1 line of
user code:
<?php
class cNode extends SimpleXMLElement {
function getName() {
return dom_import_simplexml($this)->nodeName;
}

function getType() {
return dom_import_simplexml($this)->nodeType;
}
}

$xml = '<root />';

$sxe = simplexml_load_string($xml, 'cNode');
print $sxe->getName()."\n";
print $sxe->getType()."\n";
?>

Of course XPath could be used in place of DOM too though.
