If you are looking to scrape through xpath, i recommend you to try python selenium. It supports xpath and it has threading capability. It requires very low memory footprint so it is good for VPSs too. Let me know if you need a starting template. I have shared some in BHW (but single threaded ones.. Haven't shared any multi threaded python bot in bhw yet). I can link the thread if you need.
Scrapebox isn't that good when it comes to custom scraping according to what I have seen (I have scrapebox by the way.. if anybody has a tutorial for scrapebox using xpath, please point me to that. I would appreciate your help!!)
