The getNodesByNodeValue method of a DOMIT_Document allows you to search
the document tree for nodes containing the specified nodeValue.
This is especially useful for finding text or cdata nodes
containing a certain text value.
You must pass in the node value that you are searching for as well as a contextNode
- a node from which the search should start.
The following example returns a DOMIT_NodeLIst of all nodes in the current document
with a nodeValue of "Robbie Fulks":
NOTE: in versions of DOMIT! prior to 0.5, this method returned an array, not a DOMIT_NodeList!
$myNodeList =& $cdCollection->getNodesByNodeValue("Robbie Fulks", $cdCollection);
A single text node containing the text "Robbie Fulks" will be returned.
