Output Windows |
The Output Windows (screenshot below) are located below the Main Window in the GUI. Their display is toggled on by default when you open XMLSpy. To toggle the Output Windows display on and off, click Window | Output Windows.

There are three output windows, each of which is activated by clicking its tab:
| • | Validation, which displays the results of validating XML, XML Schema, DTD, or XQuery documents. |
| • | Find in Files, which displays the results of Find and Replace operations across multiple files. |
| • | XPath Evaluation, which displays the result produced by evaluating an XPath expression against the active XML document. |
Each of the above operations is described in more detail in the sub-sections of this section.
Common features of output windows
Each output window has nine tabs. A tab is made active by clicking it. The result of the current validation, find-replace, or XPath evaluation action is displayed in the active tab. If a result is already displayed in an output tab, it is replaced by the new result. The advantage of having multiple tabs is that a result can be kept for in one tab and (i) be compared with a new result in another tab, or (ii) referred to at a later stage.
Each output window has a set of icons at the top (screenshot below).

The first two icons from left are for navigating down and up the messages in the output. The next three icons are for copying messages to the clipboard. A message can be selected by clicking on it. The next three icons are active in the Find in Files tab, and are useful for navigating the found items. The icon at extreme right is for clearing the current output tab.
