How to get the pagenumber of the content of a book

问题:

I am using Apache PDFBox version 2.0.x. I am trying to search a PDF using bookmarks and when I hit my target I should be able to get the Pagenumber the bookmark is referring to. This is my code to print all bookmarks. I can do an equals search like searchText.equals(current.getTitle())

public static void printBookmark(PDOutlineNode bookmark, String indentation) throws IOException {
    PDOutlineItem current = bookmark.getFirstChild();
    COSObject targetPageRef = null;
    while (current != null) {
        System.out.println(indentation + current.getTitle());           
        printBookmark(current, indentation + "    ");
        current = current.getNextSibling();
    }
}

If the title matches my search text then that is my target bookmark. Anyone tried this before?

I found the solution.

public static void printBookmark(PDOutlineNode bookmark, String indentation) throws IOException
{
    PDOutlineItem current = bookmark.getFirstChild();
    COSObject targetPageRef = null;
    while (current != null)
    {
        System.out.println(indentation + current.getTitle());       
        PDPageFitWidthDestination destination = (PDPageFitWidthDestination) current.getDestination();
        System.out.println("Page Number " + destination.retrievePageNumber());
        printBookmark(current, indentation + "    ");
        current = current.getNextSibling();
    }

}
