The Grammar Validator consists of a number of views:
If the Grammar Validator finds any error in a specific definition file, then the project and the folder that contains the file will be marked with an error.
If there are errors in the file, the location of the error will be marked by the Grammar Validator in the XML Editor view. The tool calculates the exact location (including line, column and length). The accurate error message will be attached to the error mark.
In the problems view, all the errors and warnings are displayed, and information about how to diagnose and amend the error is also provided. Each line in the view represents one error. When you double-click the line, the corresponding file which contains the error will be opened, and your mouse focus will be moved to the error line, and the error text will be selected.
