Change all ng- attributes to data-ng- instead

DOCO.md

So, you built an AngularJS app.

You used ng- attributes everywhere, and now your W3C validation is failing.

You wish you had used data-ng- instead.

This script will fix them all for you.

.\Fix-AllAngularAttributesForHtml5.ps1 c:\code\myapp\web\Views -TfvcAware -Verbose -PrefixesToQuality @('ng', 'app')

The -TfvcAware switch will tell the script to mark each changed file as a pending change in TFVC, if you're still stuck with it.

The -PrefixesToQualify argument lets you specify other custom directives that you might have used.
