Using "*/*" to Match Grandchildren in DOMDocument
Tips: March 2002

The pattern "*/*" matches all grandchildren of the current node. For example, if the current context is the data node in mydvd7.xml, its grandchildren will be all 12 week nodes and 3 name nodes (try it):

  var matchedNodes =   xmlDoc.childNodes[3].childNodes[1].selectNodes('*/*');
  alert("Number of matched nodes: " + matchedNodes.length);
Here is mydvd7.xml for your reference:

<?xml version="1.0"?>
