Nice! This would be doubly handy if it returned all matching
components (jQuery style). What about adding a first=True arg to make
return all matches optional ? (or some other more graceful solution
that I'm sure you've already thought of before finishing this
sentence :)
def element(self, first=True, **kargs):
components = copy.copy(self.components)
matches = []
for c in components:
try:
components += copy.copy(c.components)
check = True
for (key, value) in kargs.items():
if c[key] != value:
check = False
if check:
if first:
return c
else:
matches.append(c)
except:
pass
if len(matches): return matches
return None
