[MasterGroosha]

Now I have this JSON file

[
{
  "database_resource_url": "https://gist.githubusercontent.com/Kondra007/8fc767d278181ec72dff/raw/5ad8b5fca9952655b3303a66d6e654fde6abeb1e/AutoPaginator_Sohabr.json",
  "data": {
        "url":          "https://(.*).?sohabr.+/.*",
        "nextLink":     "\/\/ul[@class=\"pagination\"]\/li\/a[@class=\"next\"]",
        "pageElement":  "\/\/div[@id=\"wrap\"]\/div[@class=\"container\"]\/div[@class=\"posts\"]",
        "exampleUrl":   "https://sohabr.net/posts/all/page2"
  },
  "resource_url": "",
  "created_by": "",
  "name": "",
  "created_at": "2015-01-24T09:30:39+09:00",
  "updated_at": "2015-01-24T10:36:37+09:00"
}
]
