Suppose I have a table. Now, I'm interested in Getting Useful Data Easily. This means I'd rather not drop it into Excel and go through contortions, nor somehow get it into CSV and then into a DB, and then into SQL.
I'd like to be able to execute a SQL query directly against a table in HTML.
Has anyone heard of a tool like this before? I've never seen one.
No, there is absolutely no tool that lets you run SQL queries against an HTML table... but you could easily write some simple JavaScript if you had a specific query you wanted done.
There's no tool to query an HTML table with SQL as far as I know, but XQuery is a standard language you can use to find elements in an XML or XHTML source in a manner very similar to using SQL to query databases.
