Re: Bookmarks on word documents

Hi Mark,

I am also looking at retrieving bookmarks from a word document.

Can you kindly let me know if you were able to achieve it.

Regards,

Re: Bookmarks on word documents

[MSB <ma...@tiscali.co.uk>]

No, sorry no progress at all. It will require some work to accomplish this
because of the way Word stores bookmarks; crudely, it uses a data structure
where each bookmark is listed along with a number. This number indicates
where - in terms of character positions - the bookmark was actually inserted
and also where the substitution text should be placed. On one level, this is
quite simple if you ignore the complexities of locating that data structure
within the doc file, but the complications will multiply when we try to
substitute the text for the boomark at the location indicated, at least I
fear this will be the case based upon my experience with search and replace
operations. As yet, I have no idea how and what to modify when the structure
of the Word document changes and once you bear in mind that the file
'contains' up to four streams and each stream is a linked list - at least at
the most basic level - the potential problems that could be caused by
corrupting any of these links become apparent.

Yours

Mark B
