The getElementsByAttribute allows you to retrieve a single DOMIT_Element or a DOMIT_NodeList of DOMIT_Elements that contain an attribute that matches the specified name and value. This is a useful substitute for getElementByID (which can only be used with namespace awareness turned on).

To get a node list of all elements containing an attribute named 'myAttr' and a value of '3', for example, you would do this:

$myNodeList =& $xmldoc->getElementsByAttribute('myAttr', '3'); 

Note that there is a third boolean parameter for getElementsByAttribute, which if set to true will return the first matching element rather than an entire node list of elements.
