Filters out elements with non-matching explicit 'api' attributes from API XML.
To remove Vulkan SC-only elements from the combined API XML:
python3 scripts/stripAPI.py -input xml/vk.xml -output vulkan-only.xml -keepAPI vulkan
To remove Vulkan-only elements:
python3 scripts/stripAPI.py -input xml/vk.xml -output vulkansc-only.xml -keepAPI vulkansc
If you are parsing the XML yourself but using the xml.etree package, the
equivalent runtime code is:
import reg
reg.stripNonmatchingAPIs(tree.getroot(), keepAPI, actuallyDelete=True)
where 'tree' is an ElementTree created from the XML file using
etree.parse(filename)''')
parser.add_argument('-input', action='store',

help='Specify input registry XML')
parser.add_argument('-output', action='store',
required=True,
help='Specify output registry XML')
parser.add_argument('-keepAPI', action='store',
default=None,
help='Specify API name whose \'api\' tags are kept')
args = parser.parse_args()
tree = etree.parse(args.input)
if args.keepAPI is not None:
stripNonmatchingAPIs(tree.getroot(), args.keepAPI, actuallyDelete = True)
