To edit an XPath expression using the Edit XPath dialog

  1. Double-click the line representing the source to target mapping. The Edit XPath dialog appears.

  2. Edit the XPath Expression, as needed.

    For example, if you want the Description field to contain the first Comment that occurs in the source, you add a predicate to the expression with the index of the first Comment.

    Click Help if you need more information on editing the XPath expression.

  3. Click OK in the Edit XPath dialog.
