VB.NET String Parsing/Regex One Page App

Need? 1 web page/search page that takes a very large html doc/string and parses through it looking for a set of keywords in sentences. The webpage will have a search function on it.? The search will allow the user to specify a url to parse.? The search page will take that url, go get the html of that page, parse the html into sentences, and look through each sentence for keywords that will be provided in a array of keywords. The url's will be many many paragraphs and the app will need to parse those paragraphs into sentences.? Then it will need to use the provided array of keywords to search through each sentence looking for a match.? It will need to pull out the matches and bind it to a grid of results for the user to see.? AJAX/asp.net/vb.net 2005. ## Deliverables The grid that the search returns needs to have one column for keyword and the other column the sentence it found that matched that keyword. just to recap - the search accepts a url, pulls the html from that url, uses regex or some other type of string function to break the paragraphs/text/html into separate sentences.? After that it uses a array of keywords that i will provide to search the sentences looking for occurences of this keyword in the sentences.? every sentence it finds that has a keyword in it will go into a datagrid that will be sortable on keyword.? the other column will be the actual sentence with the keyword highlihgted using a span or some other kind of basic font tag.
