The XML | Validate (F8) command validates an XML document against an associated DTD, XML Schema, or other schema. If a document is valid, a successful-validation message is displayed in the Messages window. Otherwise, the causes of the error are displayed in the left-hand pane (see screenshot below). If a cause is selected in the left-hand pane, then smart fixes for it, if available, are displayed in the right-hand pane. Smart fix suggestions are based on information in the associated schema. To apply a smart fix, either (i) double-click it, or (ii) select it and click either the Fix or Fix + Validate options (see screenshot below).
In Text View, there are two additional indicators of a validation error (see screenshot below): (i) a red exclamation-mark icon in the line-numbering margin, and (ii) a red marker-square in the scroll bar (on the right of the window).
Note that the red marker-square appears on the left-hand side of the scroll bar (located at the right-hand side of the window; see screenshot above). This is mentioned because here because scroll bar displays two other kinds of marker-squares: (i) for highlighted text occurrences (brown, left-hand side of the scroll bar; see Navigating the Document); (ii) Find occurrences (brown, right-hand-side of the scroll bar; see Find and Replace).
If a smart fix is available for an error, then a light bulb icon is shown on the line that generates the error (see screenshot below). When you place the mouse over icon, a popup appears that lists available smart fixes (see screenshot). Select a fix to apply it immediately.
|Note:||Validation error indicators and quick fixes are available for document types that can be validated in XMLSpy, for example JSON documents.|
|Note:||The validation error indicators and smart fixes described above are refreshed only when the XML | Validate (F8) command is executed; they are not updated in the background. So, after correcting an error, you must run the Validate (F8) command again to make sure that the error has indeed been fixed.|
