Splitting a Word .mht document into multiple documents

I need a control developed in C# that when provided a single .mht document and the name of a style splits the original .mht document into multiple .mht documents wherever that style is encourntered in the original. Basically turning each section in the original document into a seperate document. The original provided to the control will be .mht (web archive) created in Microsoft Word (needs to work with the version of Word in Office XP, Office 2003 and Office 12 Beta). The parameters passed to the control will be a string that represents the path to the original .mht document, a string that represents the path to the folder location where the new .mht documents should be placed, and a string that represents the style (heading type) within the original document to split on. This control will be included within my C#, ASP.net web application. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Buyer in ready-to-run condition in the Buyer's environment.
