Presenting Validation Errors in Author Mode

Oxygen XML Editor plugin can be configured to automatically validate documents while editing in the Author mode, and actions are also available to manually validate documents on-request.

Validation errors are marked in Author mode with a red underline, while validation warnings are underlined in yellow. Hovering over a validation error presents a tooltip message with more details about the error and possible quick fixes (if available for that error or warning).

Information about the error is also displayed in the message area on the bottom of the editor panel (clicking the Document checking options button opens the Document Checking preferences page.

Also, the ruler on the right side of the editor panel is designed to display the errors found during the validation process and to help you locate them in the document. The ruler contains the following:

Upper Part of the Ruler: A success indicator square will turn green if the validation is successful, red if validation errors are found, or yellow if validation warnings are found. More details about the errors or warnings are displayed in a tool tip when you hover over indicator square. If there are numerous errors, only the first three are presented in the tool tip.
Middle Part of the Ruler: Errors are depicted with red markers, and warnings with yellow markers. If you want to limit the number of markers that are displayed, open the Preferences dialog box , go to Editor > Document checking, and specify the desired limit in the Maximum number of validation highlights option.
Clicking a marker will highlight the corresponding text area in the editor. The error or warning message is also displayed both in a tool tip (when hovering over the marker) and in the message area on the bottom of the application.
Bottom Part of the Ruler: Two navigation arrows () allow you to skip to the next or previous error. The same actions can be triggered from Document > Automatic validation > Next error (Ctrl + Period (Command + Period on OS X)) and Document > Automatic validation > Previous error (Ctrl + Comma (Command + Comma on OS X)).

Status messages from every validation action are also logged in the Console view (the Enable oXygen consoles option must be enabled in the View preferences page).

If you want to see all the validation error messages grouped in the Results view, you should use the Validate action from the toolbar or XML menu. This action also collects the error messages and displays them in the Problems view if the validated file is in the current workspace or in a custom Errors view if the validated file is outside the workspace.
