 No.

 Let me try to be more clear..
 Say you got the element elem key=peter , then I want the
 DOMDocument
 to automatically convert the 'key' attribute to an ID-Attribute, as
 done
 with DOMElement::setIdAttribute() function. The ID-Attribute is
 indexed
 and can be quickly gotten via DOMDocument::getElementById() function.

 I'm trying to avoid looping on all nodes overriding the importNode()
 and
 __construct() methods of DOMDocument.

Are the keys guaranteed to be unique?

If not, you can't do that, because the IDs have to be unique, no?

I suspect you'll simply have to walk the whole thing and do it the
hard way, if it's even a Good Idea...

You might be better off taking a step back and asking the list how
they solved whatever problem you're trying to solve with
auto-generating the IDs, as there may be a Better Way...

Add a DTD to the document defining your attribute as an ID.

$xml = EOXML
?xml version=1.0?
!DOCTYPE note [
  !ATTLIST elem key ID  #IMPLIED
]
doc
elem key=peterThis is Peter/elem
elem key=samThis is Sam/elem
elem key=mikeThis is Mike/elem
/doc
EOXML;

$dom = new DOMDocument();
$dom-loadXML($xml);

if ($elem = $dom-getElementByID(sam)) {
print $elem-textContent;
} else {
print Element not found;
}

Subject: [PHP] DOM Element default ID attribute

Hi,

I want to declare a default ID attribute to all elements in the document.
For example: If an element got the attribute 'id' then I want it 
automatically to become the ID attribute of the element.
How can I do that?

-thanks!
