After you have selected a root element, you can start a comparison. All global elements as well as their child elements will be mapped automatically.
Note: When comparing XML Schemas, DiffDog tries to find matching pairs of elements on both sides of the comparison rather than detecting or indicating differences between the two files. So, XML Schema comparison is about finding and indicating the parts that are equal in two XML Schemas. This approach is different from comparing files, directories, database schemas, or database data!
Do one of the following:
•Select the menu option Diff and Merge | Start XML Schema mapping or press F5.
•Right-click the title bar or any element of either component and choose Start XML Schema mapping from the context menu.
•Right-click anywhere into the XML Schema Comparison window and choose Start XML Schema mapping from the context menu.
•Right-click the tab of the XML Schema Comparison window and choose Start Comparison from the context menu.
