Finding hyperlinks inside a PDF document?

I'm currently using Aspose PDF Kit to split a 'master PDF' up into individual documents + thumbnails. This works well at the moment, but the device I'll be rendering the PDF on won't know about the annotations/links within the PDF.

I understand there is a way to parse the PDF document to detect the X/Y position of a hyperlink etc, is there an simple way to extract/iterate across the document data so I can write it to an external XML file?
