so im working on a pdf accessiblity and doesnt have much knowledge about java, so ive ask chatgpt to make a code for pdfbox the script should delete all “Span” tags but retain its child (leaf node), but the code only works properly if Span’s child tag is not a leaf node, if it is a leaf node the child tag becomes blank, ill appreciate any insights regarding this, thaaaanks

       private static void processElement(PDStructureElement element, List<Object> parentKids) {
              List<Object> kids = element.getKids();
              List<Object> newKids = new ArrayList<>();

                if ("Span".equals(element.getStructureType())) {
           
                parentKids.addAll(kids);
                       } else {
   
                for (Object kid : kids) {
                      if (kid instanceof PDStructureElement) {
                  processElement((PDStructureElement) kid, newKids);
                        } else {
                       newKids.add(kid);
                         }
                         }
                     
                   element.setKids(newKids);
                parentKids.add(element);

tried reconstructing the pdf structure and the java code
