如何使用 XWPF (Apache POI) 在 docx 绘图中获取形状

Question

我有一个带有文本和一些形状的 docx 文档。 我可以得到图纸，但是当我得到图纸时，我怎样才能得到这张图纸中的形状？ 例如，我有以下代码来解析我的文档：

  try (FileInputStream fis = new FileInputStream(file)) {
     document = new XWPFDocument(fis);
     parseDocument(document);
  }

parseDocument(XWPFDocument document)方法有以下代码（我使用了以下问题的答案： How to get graphics from the apache POI XWPFDocument? ）：

   public void parseDocument(XWPFDocument document) throws Exception {
      Iterator<XWPFParagraph> it = document.getParagraphs().iterator();
      while (it.hasNext()) {
         XWPFParagraph paragraph = it.next();
         List<XWPFRun> runs = paragraph.getRuns();
         Iterator<XWPFRun> it2 = runs.iterator();
         while (it2.hasNext()) {
            XWPFRun run = it2.next();
            List<CTDrawing> drawings = getAllDrawings(run);
            if (!drawings.isEmpty()) {
               System.out.println("Found " + drawings.size() + " drawings");
               Iterator<CTDrawing> it3 = drawings.iterator();
               while (it3.hasNext()) {
                  CTDrawing drawing = it3.next();
                  visitDrawing(drawing);
               }
            }
         }
      }
   }

   private void visitDrawing(CTDrawing drawing) {
      List<CTInline> inlines = drawing.getInlineList();
      Iterator<CTInline> it = inlines.iterator();
      while (it.hasNext()) {
         CTInline inline = it.next();
         CTGraphicalObject graphic = inline.getGraphic();
         if (graphic != null) {
            CTGraphicalObjectData graphicData = graphic.getGraphicData();
            if (graphicData != null) {
               XmlCursor c = graphicData.newCursor();
               c.selectPath("./*");
               while (c.toNextSelection()) {
                  XmlObject o = c.getObject();
                  System.out.println(o);
               }
            }
         }
      }
      
      List<CTAnchor> anchors = drawing.getAnchorList();
      Iterator<CTAnchor> it2 = anchors.iterator();
      while (it2.hasNext()) {
         CTAnchor anchor = it2.next();
         CTGraphicalObject graphic = anchor.getGraphic();
         if (graphic != null) {
            CTGraphicalObjectData graphicData = graphic.getGraphicData();
            if (graphicData != null) {
               XmlCursor c = graphicData.newCursor();
               c.selectPath("./*");
               while (c.toNextSelection()) {
                  XmlObject o = c.getObject();
                  System.out.println(o);
               }
            }
         }
      }      
   }

   private static List<CTDrawing> getAllDrawings(XWPFRun run) throws Exception {
      CTR ctR = run.getCTR();
      XmlCursor cursor = ctR.newCursor();
      cursor.selectPath("declare namespace w='http://schemas.openxmlformats.org/wordprocessingml/2006/main' .//*/w:drawing");
      List<CTDrawing> drawings = new ArrayList<>();
      while (cursor.hasNextSelection()) {
         cursor.toNextSelection();
         XmlObject obj = cursor.getObject();
         CTDrawing drawing = CTDrawing.Factory.parse(obj.newInputStream());
         drawings.add(drawing);
      }
      return drawings;
   }

对于内联绘图和锚定绘图， XmlObject元素包含我可以看到的形状，当我查看打印内容时，在非常简单的示例中就是这种情况），但是当我拥有对象时如何获得这些形状？
