check_update
(root, options=None)¶ Determines if the input document can be upgraded.
Parameters: - root – The XML document. This can be a filename, a file-like object,
an instance of
etree._Element

update
(root, options=None, force=False)¶ Attempts to update root to the next version of its language specification.
If force is set to True, items may be removed during the translation process and IDs may be reassigned if they are not unique within the document.
Note
This does not remap
idref
attributes to new ID values because it is impossible to determine which entity theidref
was pointing to.Removed items can be retrieved via the
removed
attribute on the return value:>>> results = updater.update(root, force=True) >>> print(results.removed) (<Element at 0xffdcf234>, <Element at 0xffdcf284>)
Items which have been reassigned IDs can be retrieved via the
remappped_ids
attribute on the return value:>>> results = updater.update(root, force=True) >>> print(results.remapped_ids) {'example:Observable-duplicate-id-1': [<Element {http://cybox.mitre...
