Mapping Statements

Mapping Statements

A mapping statement determines how to map data from the input hierarchical document to the output hierarchical document. When you drag a node from the input schema to the output schema, the XMap editor creates mapping statements in the grid.
You can use the grid to create simple or detailed mapping statements. You can drag elements from the input or output schemas into fields in the grid to include them in mapping statements.
You can check the element that a mapping statement references. When you click a mapping statement in the grid, the XMap editor highlights the nodes in the schemas.
Add XPath expressions to determine the context or add computations to a mapping statement. When an XPath expression identifies the context for a mapping statement, the Data Processor transformation runs the mapping statement for each occurrence of the input element or expression in the input document.
Nest mapping statements to make them dependent on other mapping statements. A mapping statement can be a parent to a group of child statements. Each time that the Data Processor transformation runs the parent statement, it runs the child statements also. Child statements appear indented from the parent in the XMap editor.
