      The problem is that I won't know how many layers meet the criteria
      in advance. Is there some javascript command or method that would
      give me the number of layers with an ID beginning with "showMe".

      You could do something like

      var i = 1;
      while(layer = mySVG.getElementByID("showMe"+i") != null){
      i += 1;

      assuming they count sequentially up from 1 with no gaps.
