How to Use the XPath Building Assistant
This section provides an example of using the XPath Building Assistant to build an expression in the Expression field of the Expression Builder dialog.
To use the XPath Building Assistant:
- Make a selection from the list in either of the following ways:
-
Scroll down the list and double-click a function.
-
Enter the beginning letter (for example,
c) to display only items starting with that letter, and double-click the appropriate function.
