Write a Visual Web Scrapper, in MVC .Net, based on Portia (Python - github)

Write a .net port, in C# and asp.net mvc, of the Portia project, that can be found on [login to view URL] . Video demo here:[login to view URL] WARNING: This project was already cancelled once! Only apply if you have .net and python professional skills! I am a pro coder, and i know how to identify bad coding. I need a good coder, not a begginer. Project only finish when all features and expectations described above are completed. Introduction: - I have a web crawler that is used to scrape information from some websites, and i compile the information to a site I have. I work on this project on my own on weekends, and I am having a big problem that, very often, the websites that I scrape change the layout, or have variable layouts, like templates in Portia understanding. I need a easy way of updating this templates for a website, i a way that i can save as a project, and call this project on my crawler to extract the data of given urls, or html string texts. Given this idea, I think a Portia-like implementation, would be great. And, as I already have a crawler, I would not need the advanced crawler based on 'Scrapy'. I just need a way to create the scraper project for a site while navigate in the site inside the webapplication, and a way to extract the data later in my crawler, by calling a class library, passing project name and url (or html string), and get the existing propertys of the extraction. Key features: - Fully written in C#; - Cannot use database. Projects must be saved as file. - 2 Projects: - One WebApplication: for visually build scraping templates for a given site project. Generally, for each site project, I will have a template for listing page and one for details page, but both can have template variations, depending type of product, category, or cases where DOM/Xpaths changes when product has less or more information. - One class library: that given a url or given a html string, and a project (created on the web application) name, i can extract all data based on the extraction rules created on the web project. I want to call this class library from my existing crawler project. Expectative: - Web Application Expectations: -> Same features as Portia web application, considering: -> Easy configuration for projects directory path; -> List Projects feature; -> Possibility of 'Create new Project', 'Load Project', 'Save Project', 'Close Project(to select other project, initial app state)'; -> Visually navigate the site and select the information to be crawled, with possibility to customize rules, like Portia; -> Possibility to have a list of starter urls. In this list i will keep the most common result pages that will list me produtcs. So can be easy to navigate directly for the listing page (to build that template) and after to the detail page (and build another template). -> Possibility to create templates exactly as Portia. - Class Library Expectations: -> Public, easy to be used from other assemblies; -> Easy to use and fast; -> Can use HtmlAgilityPack and CsQuery; -> Possibility to pass/set a HttpWebRequest (in case im using a proxy or different agent headers); -> Possible input parameters for extraction method: -> string 'project name' and Uri'url to extract'; -> string 'project name' and string 'html'; -> string 'project name', string 'template name', and Uri'url to extract'; -> string 'project name', string 'template name', and string 'html'; -> Output: -> List of propertys, ready to be indexed by my crawler as soon it call/executes the extraction. I'm thinking in some type of dictionary, that i can search if the key exists, so I can pick the value and store on my data storage. -> Would be great if the result was a context, with a field with the extractions dictionary, and other fields that list errors occured during parse, template used, and other relevant informations.
