Question

这是一种奇怪的情况。我正在制作一个pdf文件，其中只有一个书签名称，但在此书签下有42个书签嵌套或子书签。我不知道如何提取这个，因为我没有看到任何可用的选项。虽然我已将此问题发布到pdf框队但尚未回复。任何人都可以建议任何选项或解决方案吗？以下是我的pdf

中书签的结构

MainBookMarkName
|_firstBookMark (1-10 pages)
|_secondBookMark (1-5 pages)
|_thirdBookMark (1-8 pages)
|_FourthBookMark (1-15 pages)
|_
|_
|_lastBookMark (42)

以下代码只会加载＆＃34; MainBookMarkName＆＃34;并打印所有嵌套书签，但不循环每个书签或提取其中任何一个。所有页面仅与嵌套书签相关联，而不是主书签。
