An XMap requires hierarchical schemas that define the input and output hierarchical hierarchies. An XMap uses input and output hierarchical schemas to determine what type of data is expected in the input source document and output document. You link input and output schema nodes to create mapping statements.
A schema element is the basic building block of a mapping statement. When you define a mapping statement you might want to use a series of input schema elements in the statement, or add a variable. You can change the input and output root, add variables, and customize the schema view, but cannot edit the schema.
You can use the following options to manage the schemas and search for elements:
Changes the way the schema appears so you can quickly search for relevant elements. You can search for a sequence of nodes, all nodes, or a choice of nodes. View these nodes to understand the schema logic. This view do not affect the mapping.
Search for elements in the schema. You can search in the input and output schemas separately.
Define variables to store data. You can map nodes to variables and map variables to nodes. You can also map variables to variables. When you create a variable, the variable appears at the bottom of both schemas.
Select Input or Output Root
Change the root element in the input or output schema. You might change the root element in order to reference a different part of the schema.
Choose the example source
Define the example source file. Use an example source to test the transformation and to test XPath expressions.
