The only other function invoked by the makeHTML() function is calcBlockState(). This function looks into one of the OPML outline s HEAD elements, called EXPANSIONSTATE. This element s values can be set to a comma- delimited list of numbers corresponding to nodes that are to be shown expanded when the outline is first displayed. The calcBlockState() function is invoked for each parent element. The element s location is compared against values in the EXPANSIONSTATE element, if there are any, and returns the appropriate 1 or 0value for the state string being assembled for the rendered outline.
