如何使用apache poi获取pptx幻灯片笔记文本？

Question

到目前为止，我只有一个从ppt幻灯片笔记中检索文本的工作代码

try {
    FileInputStream is = new FileInputStream("C:\\sample\\test.ppt");
    SlideShow ppt = new SlideShow(is);

    Slide[] slide = ppt.getSlides();
    for (int i = 0; i < slide.length; i++) {

        System.out.println(i);
        TextRun[] runs = slide[i].getNotesSheet().getTextRuns();
        if (runs.length < 1) {
            System.out.println("null");
        } else {
            for (TextRun run : runs) {
                System.out.println(" > " + run.getText());
            }
        }
    }

} catch (IOException ioe) {

}

但如何从pptx幻灯片笔记中检索文本呢？

对已接受答案的更新。这很有效，但是如果您启用了笔记母版中的其他部分，例如页眉或页码，那么您将获得您可能不期望的额外笔记段落。您可以使用以下代码将实际笔记限制为：

try {

    FileInputStream fis = new FileInputStream("C:\\sample\\sample.pptx");
    XMLSlideShow pptxshow = new XMLSlideShow(fis);

    XSLFSlide[] slide2 = pptxshow.getSlides();
    for (int i = 0; i < slide2.length; i++) {
        System.out.println(i);
        try {
            XSLFNotes mynotes = slide2[i].getNotes();
            for (XSLFShape shape : mynotes) {
                if (shape instanceof XSLFTextShape) {
                    XSLFTextShape txShape = (XSLFTextShape) shape;

                    // Look for the actual notes only ...
                    if (!txShape.getShapeName().contains("Notes Placeholder")) {
                        continue;
                    }

                    for (XSLFTextParagraph xslfParagraph : txShape.getTextParagraphs()) {                    
                        System.out.println(xslfParagraph.getText());
                    }
                }
            }
        } catch (Exception e) {

        }

    }
} catch (IOException e) {

}

经过不断的反复试验，找到了解决方案。

try {

    FileInputStream fis = new FileInputStream("C:\\sample\\sample.pptx");
    XMLSlideShow pptxshow = new XMLSlideShow(fis);

    XSLFSlide[] slide2 = pptxshow.getSlides();
    for (int i = 0; i < slide2.length; i++) {
        System.out.println(i);
        try {
            XSLFNotes mynotes = slide2[i].getNotes();
            for (XSLFShape shape : mynotes) {
                if (shape instanceof XSLFTextShape) {
                    XSLFTextShape txShape = (XSLFTextShape) shape;
                    for (XSLFTextParagraph xslfParagraph : txShape.getTextParagraphs()) {
                        System.out.println(xslfParagraph.getText());
                    }
                }
            }
        } catch (Exception e) {

        }

    }
} catch (IOException e) {
