Buggy source:
public Element processTag(Element ele,Attributes attrs){
  String type=attrs.getValue("String_Node_Str");
  String value=attrs.getValue("String_Node_Str");
  if ("String_Node_Str".equals(type)) {
    Element w=OSISUtil.factory().createW();
    w.setAttribute(OSISUtil.ATTRIBUTE_W_LEMMA,OSISUtil.LEMMA_STRONGS + value);
    ele.addContent(w);
    return w;
  }
  if ("String_Node_Str".equals(type)) {
    Element div=OSISUtil.factory().createDiv();
    div.setAttribute(OSISUtil.ATTRIBUTE_DIV_OSISID,"String_Node_Str" + value);
    ele.addContent(div);
    return div;
  }
  if ("String_Node_Str".equals(type)) {
    Element div=OSISUtil.factory().createDiv();
    div.setAttribute(OSISUtil.ATTRIBUTE_DIV_OSISID,"String_Node_Str" + value);
    ele.addContent(div);
    return div;
  }
  DataPolice.report("String_Node_Str" + type + "String_Node_Str"+ value);

      siblings.set(size - 1,w);
