如何使用 apache poi 獲取 pptx 幻燈片注釋文本？

Question

到目前為止，我只有一個用於從 ppt 幻燈片筆記中檢索文本的工作代碼

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) {

}

但是如何從 pptx 幻燈片筆記中檢索文本？

Answer 1

經過不斷的反復試驗，找到了解決方案。

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) {

}

已接受答案的更新。 這很有效，但是如果您啟用了注釋主文件中的其他部分，例如 header 或頁碼，那么您將獲得您可能沒有預料到的額外注釋段落。 您可以使用以下代碼僅限於實際注釋：

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) {

}

給出更好的解決方案。

try (FileInputStream fis = new FileInputStream("C:\\sample\\sample.pptx")) {
    XMLSlideShow ppt = new XMLSlideShow(fis);
    List<XSLFSlide> slides = ppt.getSlides();
    for (XSLFSlide slide : slides) {
        try {
            XSLFNotes mynotes = slide.getNotes();
            for (XSLFShape shape : mynotes) {
                if (shape instanceof XSLFTextShape && Placeholder.BODY == ((XSLFTextShape) shape).getTextType()) {
                    XSLFTextShape txShape = (XSLFTextShape) shape;
                    System.out.println(txShape.getText());
                    break;
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
} catch (IOException e) {
    e.printStackTrace();
}

與其他答案不同，此代碼使用Placeholder.BODY == ((XSLFTextShape) shape).getTextType()以便您只能獲取備注文本。
