Add link to PDF file

Suppose a PDF file has some URL string like http://abc.com and also has some email address string, such as xyz@abc.com and also has a table of contrnts. Is there any programming way

1. Extract those URL or Email String
2. Add link (action) to those URL or Email string so when user click URL, it will bring browser to that URL, when user click email address, it will bring up some email software, such as Outlook to get a email dialog window.
3. Add some link to the table of content so when user click a chapter line in the table of contents, then PDF jump to the page of the start of that chapter.

Thanks,
P
