""" XAML Formatter and Validator for WinUI3

This application is designed to format and validate XAML code used in WinUI3 applications. It provides real-time syntax highlighting, detailed error checking, and progress tracking for formatting and validation operations.

Features:

1. Real-time Syntax Highlighting:

   • The application updates the text color dynamically as the user types in the main text box.
   • Elements, attributes, values, and errors are highlighted in different colors for better readability.

2. Formatting and Validation:

   • The "Format and Validate" button triggers the formatting and validation process.
   • The application parses the XAML input, formats it neatly, and validates it against common XAML errors.
   • Errors are highlighted in the text box and detailed error messages are displayed in the output text box.

3. Logging and Output:

   • A second text box is provided below the main text box for logging and output messages.
   • The output text box displays messages about the progress and results of the formatting and validation operations.

4. Progress Bar:

   • A progress bar is included to show the progress of the formatting and validation operations.
   • The progress bar updates from 0 to 100, reflecting the current operation's progress.
