8.3.2 Importing models from XML
Importing XML models into MetaEdit+ will always create new
models, without affecting existing models.
To import data in XML format:
| 1) | Press
the Import button on the Launcher toolbar (or alternatively select
Repository | Options, activate the Repository tab and press the
File in Patches button). This will open a file dialog from which you pick
the XML file to be
imported. |
| 2) | Choose
the .mxm file to import and press
Open. |
Please note that as the XML
import file does not contain the metamodel information, you have to make sure
that the file to be imported is compliant with your current metamodel.
During import, the XML file is first parsed. If an error
occurs at this stage, you will be told the cause of the error and approximate
position. After closing the error dialog, you can correct the file and safely
attempt to import again.
After parsing, the XML elements are processed, creating
new GOPPRR elements. Errors can still occur at this stage: for instance a type
name may not exist. If an error occurs at this stage, you will be told the cause
of the error and its approximate position, and that you should abandon the
current transaction. After closing the error dialog you should thus abandon the
transaction, to remove GOPPRR elements that have been only partially imported,
and are likely to contain errors.
As with all imports, you should check the imported data
after importing, and only commit the transaction if there are no
problems.
