Description

This attribute is read-only and the returned value may be:

0-UNINITIALIZED: XML objects are generated, but no files are loaded.
1-LOADING: The LOADING program is in progress, but the file has not started parsing.
2-LOADED: some files have been LOADED and parsed, but the object model has not yet taken effect.
3-INTERACTIVE: only valid for some loaded files. In this case, the object model is valid but read-only.
4-COMPLETED: the file is fully loaded, indicating that the file is successfully loaded.
