Create a AttributeIterator object.

Params:
  • compiler – A reference to the Compiler that contains the op map.
  • opPos – The position within the op map, which contains the
location path expression for this itterator.
Throws:

   * @param compiler A reference to the Compiler that contains the op map.
   * @param opPos The position within the op map, which contains the
   * location path expression for this itterator.

Get the next node via getFirstAttribute && getNextAttribute.

Returns the axis being iterated, if it is known.

Returns:Axis.CHILD, etc., or -1 if the axis is not known or is of multiple
types.
