I am working on PHP5 and all the xmldom related extensions are
installed and on properly.
I am trying to execute following code but some how not working.


$doc = new DomDocument();
$doc->validateOnParse = true;
$doc->load('abc.xml');
//xml file contains one element with this id
$elem = $doc->getElementById( 'eee' );

if(is_null($elem)) {
echo "<br>IT IS NULL";
}
else {
echo "<br>NOT NULL.";
}

The output shows me null every time...
Why is that?????

The manual hints towards why:

"According to the DOM standard this requires a DTD which defines the attribute
ID to be of type ID. You need to validate your document with
DOMDocument->validate() or DOMDocument->validateOnParse before using this
function."

You've set validateOnParse, but you haven't posted the contents of abc.xml.

Does it include a DTD that defines ID?

There is a link in the user contributed notes to the following site that
explains all:
