Get XPath

Given a node this will return an array containing the XPath
Usage:

getXPath(document.getElementById('myelement'));

      function getXPath(node, path) {
        path = path || [];
        if(node.parentNode) {
          path = getXPath(node.parentNode, path);
        }

        if(node.previousSibling) {
          var count = 1;
          var sibling = node.previousSibling
          do {
            if(sibling.nodeType == 1 && sibling.nodeName == node.nodeName) {count++;}
            sibling = sibling.previousSibling;
          } while(sibling);
          if(count == 1) {count = null;}
        } else if(node.nextSibling) {
          var sibling = node.nextSibling;
          do {
            if(sibling.nodeType == 1 && sibling.nodeName == node.nodeName) {
              var count = 1;
              sibling = null;
            } else {
              var count = null;
              sibling = sibling.previousSibling;
            }
          } while(sibling);
        }

        if(node.nodeType == 1) {
          path.push(node.nodeName.toLowerCase() + (node.id ? "[@id='"+node.id+"']" : count > 0 ? "["+count+"]" : ''));
        }
        return path;
      };
