Fetching a list of all "child URLs" from a root URL?

For example, if I enter a root URL of exampleee.com/

I would like to be returned with a list of all child URLs of this URL,

such as http://ift.tt/2gdZKvb, http://ift.tt/2gBtPZ8, http://ift.tt/2ge01hC.

Is there a programming language that is capable of achieving this? And if so, what kind of libraries/API will I need?

I would like to repeat this action for around 500+ different root URLs, so efficiency would be great :)

Thank you all.
