Overview
WDS MS SQL CLR Functions is a set of functions embeddable into an MS SQL Server instance to crawl through web resources and scrape data from them.
The functions are packed in a single .NET Framework library. This library is open source, so everyone can review this to check what data it sends, what it receives, and how it handles it - wds.mssql.clr
