Roy Osherove has released a new Regular Expression (alpha) tool:
"Regulazy is an attempt to build a small "Expert System" for creating .NET Regular Expressions.
It lets the user create an expression based on a real life example of text they would like to parse.
As the user interacts with Regulazy using the mouse, Regulazy offers the user possible expressions that would fit the currently selected text. As the user selects "rules" to apply on various parts of the text,
a regular expression is built automatically in the lower application pane.
The end result is a visual expression builder, that for most simple parsing operations, requires the user only to know what they would like to parse, and what the parsing rules should be - Regex Syntax is *not* needed."
