Data retrieval from web pages using C#, ASP.NET, regular expression

We developed a business directory the web pages we created are still available, but the source data which created them is missing. We need to retrieve the source data from the web pages, by parsing the source code of the HTML files. You will develop a piece of software in C#, which will open a given input file containing the source HTML and parse it using one or more regular expressions. It will send the resultant data to a Microsoft Access database. Not all of the data is present on every page. For example Address 2 is present on some pages but not on others. So the regular expressions have to be very accurate. It will open the file from the file system, not from the web. It does not need to loop through a series of input files, although we may enhance it to do so. The software need only open one source file at a time. The following information must be extracted: Company name Address Address 2 Locality Town County Postcode Region Type of Business SIC Code Premise Type No. of Employees Phone No. Website Address Years Established Financial Year End Turnover Est Turnover Profit Before Tax Net Worth Exports For compatibility with our systems, it should be written using .NET in C#. IDEALLY it should be as an ASP page which we can run on our intranet server. However, as long as it is in C# .net we will be happy.
