### Expression page

This page appears on the XQuery/XSLT Expression Editor, the XPath Expression Editor, and the Condition Editor.

The Expression page contains a text field where you can build expressions by typing directly into the field or by dragging items from the Variable Structures page or the XQuery Functions page on the right side of the editor.

Click Test to test the expression in an ALSB domain on a running server. WebLogic Server is packaged with ALSB, so an installation of ALSB includes an embedded server you can use for testing purposes.
