you can also write this more concisely:

model = self._api_models.GetModel(api_name).Get()
return model.description if model else ''

*however* I do see the problem here now. This code should be using
self._api_models.GetNames(), not the features bundle at all. That would really
simplify this.

So in the loop below, instead of having

for api in FilterAPIs(platform):
  ... complicated logic

you would have

api_features = self._features_bundle.GetAPIFeatures()
for api_name in self._api_models.GetName():
  if platform not in api_features[api_name]['platforms']:
    continue
  api_model = self._api_models.GetModel(api_name)
  ... api_model.description and so on

[hukun, 2013/11/08 06:23:39]

I did filter the api by _api_models.GetName() before getting description. You
could see the codes at line 110. But, this functioin "_CreateAPIModel" in
api_models.py will get schema as "None", so that I add one line "if not schema:
return None" in api_models.py.

One example is "musicManagerPrivate". 

1) ProcessSchema will return None, so scheme is None. But, use
schema['namespace'] will throw exceptio due to None ref

2) Inside ProcessSchema, RemoveNoDocs is called. By design, RemoveNoDocs will
return true due to "[nodoc]" element.

So, I am not sure if it is by design or buggy. I would like to help fix this
issue if need. 

Listen to your opinion to go ahead.

Oh because they have [nodoc]. Right. That is a problem that I'd like to fix,
but, we can do it later. Nice catch, thanks. Could you add a comment and
reference crbug.com/317197 here?

some of these commas need spaces after them

See comment above. Just loop over self._api_models.GetNames(), this will be
simpler. You shouldn't need FilterAPIs etc.
