Hi,
I have a directory tree with various XML configuration files.
I then have separate classes for each type, which all inherit from a base. E.g.
class AnimalConfigurationParser:
...
class DogConfigurationParser(AnimalConfigurationParser):
...
class CatConfigurationParser(AnimalConfigurationParser):
....
I can identify the type of configuration file from the root XML tag.
I'd like to walk through the directory tree, and create different objects based
on the type of configuration file:
for root, dirs, files in os.walk('./'):
for file in files:
if file.startswith('ml') and file.endswith('.xml') and 'entity' not
in file:
with open(os.path.join(root, file), 'r') as f:
try:
tree = etree.parse(f)
root = tree.getroot()
print(f.name)
print(root.tag)
# Do something to create the appropriate type of parser
except xml.parsers.expat.ExpatError as e:
print('Unable to parse file {0} - {1}'.format(f.name,
e.message))
I have a dict with the root tags - I was thinking of mapping these directly to
the functions - however, I'm not sure if that's the right way to do it? Is
there a more Pythonic way of doing this?
root_tags = {
'DogRootTag': DogConfigurationParser(),
'CatRootTag': CatConfigurationParser(),
}
Cheers,
Victor
