How can I find a list of all the links we have in our macros and dynamic content?

Hi all,

We are about to merge/delete some of our help centre articles and in many of our macros (and dynamic content), we link to articles. We therefore need to be able to create a list of all the links we have added to our macros, so that we can update them with the new article links. 

Is there a way to do this, like an export for example? Or a search feature?
