The Python Package page can be found here Usage XVFB only works on Linux and if the parameter is True on a Windows or MacOX system you will get an error message. The tool is build on top of several other packages which will be automatically installed. Using pip3 install dr-web-engine or integrating with the tools command line interface by running python3 -m web_nner The tool is written in Python3 and can be included in other python projects by installing it from the python package index We opted for using JSON constructs for our query definitions with augmented keywords, filters and actions. Similarly to OXPath, our objective is to create a tool for data retrieval from the web based on a "query" mechanism. Our inspiration comes form OXPath where an extension of XPath is used to "query" and extract semi-structured data from the web. We took a different perspective and looked at querability feature. Multiple technologies are used as web parsers, web scrapers, spider and so forth.Ĭomparative studies can be found in literature thatĬategorise based on methods and technologies. ![]()
