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
|
|
<link linkend="function.dom-domdocument-validate">DOMDocument->validate()</link>
|
|
or <literal>DOMDocument::validateOnParse</literal> before using this function.
