Scraping PostUrls from Pages with Keywords

Hey Guys,

i'm looking for a tool for scraping PostUrls which contain defined Keywords. For example scanning page xy every day and looking for posts which contain the keyword "car" or any other keyword within the posttext. And then build lists with posturls like fb.com/pageid/postid. actually i'm doing that with massplanner campaigns in the "share Post" category. worked really fine several years. so i'm very sad about the massplanner info...

Best Pete
