|Validating XML Documents / Validating XML Documents Against a Schema|
Use one of the actions for validating the currently edited document:
The Validation options button available on the Validate toolbar allows quick access to the validation options of the built-in validator in the Oxygen XML Editor user preferences page.
Also you can select several files in the Project panel and validate them with one click by selecting the action Validate selection, the action Validate selection with Schema ... or the action Configure Validation Scenario ... available from the contextual menu of the Project view.
In case too many validation errors are detected and the validation process takes too long, you can limit the maximum number of reported errors from the Preferences page.
