Visual Studio 2005 Tips
I find myself using Visual Studio 2005 more and more to help edit HTML files. The IDE has some very nice features that make validating doctypes and cleaning up old HTML a snap. For example, if you right click on an HTML document while in HTML Source Mode and choose "Formatting and Validation" you can set the doctype the IDE uses to validate your HTML. After opening the "Formating and Validation screen choose the Validation menu option then select your doctype.
