Building Expressions

Expressions are constructed using the Build tab. The Build tab consists of three sections. The Source Dictionary pane section, the Shortcuts, XPath Operators and XPath Functions tabs section and the Expression pane section.

An XPath expression may be constructed manually, by typing directly into the Expression area of the dialog. In addition, source file attributes for inclusion in the expression may be selected from the Source dictionary, by navigating to the required element in the source dictionary tree view and double clicking on the required attribute. This attribute will then be added to the expression.

Additional elements for constructing an XPath expression are provided on the Shortcuts, XPath Operators and XPath Functions tabs.

Once the required expression has been constructed, select the OK option to close the dialog. The expression is then displayed in the relevant field in the main Attribute Mappings dialog.
