Those “bookmarks” form a tree structure, with chapters and sections, and include (hyperlink) targets in the PDF. What kind of output would be useful for what you are trying to do, a flat vector of strings, or do you need the nesting information? Do you need the link targets?

(Not saying I have a solution for any of these, but it would help in trying to answer your question.)

@Christopher Creutzig, if you're particularly interested in/knowlegeable of pdf file interaction, you might find <another recent question> of some interest.

High level MATLAB functions including extractFileText, pdfinfo and readPDFFormData in the <DataAnalyticsToolbox> don't return the bookmarks; you'll have to have some 3rd party pdf toolset to be able to do that...there are some like <itext bookmark example> that utilize code in a DLL that you would have to write mex code in your language of choice to use.

All you can do with high-level MATLAB will be to <search for known strings or patterns>.
